Roborock S7 UK Review (2024)

Roborock S7

Last updated: 07.07.2023 Reading time: 14 Min.

The Roborock S7 robot vacuum exceeds all our expectations in the tests!

That’s thanks to numerous innovations:

  • A vibrating mopping function (sonic mopping),
  • A liftable mopping plate for carpets (VibraRise) and
  • An auto-empty dock (from mid-2021).

The only thing the Roborock S7 can't do (yet) is fly or climb stairs?.

What’s more: the price also speaks for itself and is in a very acceptable range (especially compared to the competition), even though it has such an abundance of high-tech features.

That’s almost too good to be true... There’s got to be a catch, right?

We put the Roborock S7 through the wringer in our extensive tests, and now we can tell you all about our experiences!

Holding the Roborock S7 high during the review


  • Sonic Mopping (vibrating mopping plate) significantly improves the mopping results
  • The robot lifts the mopping plate whenever it drives over a carpet (VibraRise)
  • You can use the self-emptying dustbin with either a reusable or disposable dust bag
  • Suitable for houses with several floors (It can save up to 4 maps)
  • Maintenance-free rubber brush
  • Excellent app
  • Outstanding cleaning results on hard floors and carpets
  • Efficient and seamless navigation
  • Good carpet detection function (it marks carpets on the map)


  • Delivery scope doesn’t include a cleaning tool
  • Very sharp/pointed objects (e.g. broken glass) can damage the rubber brush
  • VibraRise (liftable mopping plate) doesn’t work that well on very high carpets
  • Pretty loud in the highest cleaning mode
  • Delivery scope isn’t that extensive

All important facts at a glance

  • They significantly improved the mopping function with the vibrating mopping plate (sonic mopping)
  • The robot automatically lifts the mopping pad when it drives onto a carpet (VibraRise)
  • Pet hair or long human hair hardly wraps around the brush (the robot vacuum has a maintenance-free rubber brush).
  • Auto-empty dock won’t be available in the UK until autumn 2021.

Roborock S7: Vacuum Review

Every robot vacuum cleaner has to go through our challenging cleaning tests.

We spread 50 grams of oat flakes, sand and lentils one after the other on laminate and carpets (low pile/high pile). Then we check how the vacuum cleaner copes with it.

The Roborock S7 fulfils all requirements - at least on paper:

  • 2500 Pa suction power
  • A dust container with a capacity of 470 ml.
  • Main brush made of plastic (hair can’t wrap itself around it)
  • An oscillating main brush (better adaptation to uneven floors)

Cleaning test on the laminate

First, the Roborock S7 had to show what it’s got on the laminate.

The result was very good!

Neither lentils (100%)...

And what about sand?

The Roborock S7 hardly reached its limits with that, either! It removed a whopping 96% of the sand on the laminate.

No Problem!

The results speak for themselves: The Roborock S7 cleans hard floors without any problems.

The cleaning performance here is impeccable.

The Cleaning Test on Carpets

Hard floors don’t pose a threat to the Roborock S7.

But what about carpets?

The robot vacuum cleaner has a carpet detection function. The Roborock S7 automatically increases the suction power to "Max" as soon as it drives onto a carpet.

Furthermore, the Roborock S7 is equipped with special " knobs". These "roughen" the carpet a little . In this way, the dirt can be vacuumed better.

Another novelty: The Roborock S7 sweeps the carpet’s edges first. That’s where a lot of dirt usually hides, so the robot vacuum gets a better hold of it. After that, the robot moves on to clean the rest of the carpet.

We test the cleaning performance on a high pile/low pile carpet.

The Roborock S7 came out with flying colours here, too!

Test result on a low carpet:

The Roborock S7 removed the lentils with gusto!

The vacuum-mopping robot had no problems cleaning both the high pile carpet (100%) and the low pile carpet (100%).


It reliably removed the coarse oat flakes on the high carpet (49 %) and the low carpet (100 %), too.

Sand on a carpet is usually more challenging for a vacuum cleaner.

It takes very powerful suction to remove the heavy sand from the carpet fibres.

But the Roborock S7 did a great job here, too.

It removed 80% on the low carpet....

... and 90% on the high pile carpet. That makes the Roborock S7 one of the premium robot vacuums on the market.

How well does the Roborock S7 clean in Everyday Life?

We let the Roborock S7 clean our apartment over several weeks after the excellent results in our "extreme cleaning test".

Our hard floors (laminate, PVC and tiles) were a piece of cake for the Roborock S7.

The "Balanced" cleaning mode was utterly sufficient to remove 100% of the "everyday dirt".

The robot won’t miss a single spot in the apartment, thanks to the excellent laser navigation.

Long story short: We were thrilled!

The New Rubber Brush: Pet and Human Hair can’t stand a chance

The rubber brush is one of Roborock’s many innovations.

Holding the Roborock S7's rubber brush in the hand

The Roborock S7's new rubber brush solves a nagging problem with robot vacuums:

From now on, hair (neither pet hair nor long human hair) can’t wrap itself around the brush anymore.

(It’s a different story with an ordinary bristle brush...).

The result in our hair suction test confirmed that:

Roborock S7 in the hair cleaning test

Hair is in the dirt container of the Roborock S7

You won’t even have to remove those few hairs that get caught in the rubber brush with scissors (or a cleaning tool).

You can easily pull out the hair.

Removing hair from Roborock S7's rubber brush

Removing hair from the Roborock S7 rubber brush

That makes the Roborock S7 very suitable for pet owners.

Nevertheless, there was one slight drawback.

The S7 doesn’t come with a cleaning tool.

Even though we won’t need it for the main brush, hairs could still get caught in the side brush from time to time.

You’ll have to remove them with conventional scissors.

The Roborock S7’s rubber brush also has a disadvantage:

Sharp/very pointed objects can damage the brush more easily.

You shouldn't let your Roborock S7 vacuum broken glass (or other sharp objects).

Cleaning in Corners and Along the Ledges

Let’s cut to the chase.

The cleaning along the ledges is excellent.

The Roborock S7 moves very close to the ledges, thanks to the unique "wall sensors". The Side Brush sweeps out the dirt so that the robot can suck it up.

Roborock S7 vacuums along the ledges

It also did a great job cleaning corners.

Roborock S7 vacuums a corner

The result is very satisfactory, considering that it’s a round-shaped robot vacuum cleaner.

Only the D-shaped robot vacuums (e.g. Roomba S9) performed better.

However, these are relatively rare, as they have numerous other disadvantages.

Roborock S7: The Mopping Function

Roborock UK went that extra mile with the mopping function.

That’s where you can spot most of the S7’s innovations.

  • The increased weight of the robot vacuum and more substantial contact pressure of the mop
  • The robot lifts the mopping whenever it drives onto a carpet (VibraRise)
  • The vibrating mopping function (sonic mopping)
  • A “Deep Cleaning Mode” (Only for the mopping function)

Check Amazon*

We’ll talk more about each feature below.

Higher Weight and Increased Contact Pressure

Mopping robot vacuums struggle with one fundamental problem. Their weight is too low.

That’s why they can’t put enough pressure on the mop pad. Thus, the robot vacuums have a hard time removing stains that have dried for days.

The manufacturer came up with two countermeasures here:

The Roborock S7 brings about 5 kg to the scale, which is a lot heavier than most of its competitors or predecessors.

It also has a unique device that applies an additional contact pressure of ~580 grams to the mop.

A unique device applies an additional 580 grams of pressure to the mop

These two measures ensure an improved mopping result.

The robot vacuum can clean even more stubborn stains better (where it must apply a lot more pressure to the mop).

The VibraRise Technology

The Roborock S7 has ultrasonic carpet detection technology.

It detects the carpet... and lifts the wiping plate by approx. 4-5 mm when driving over it!

They called this new technology the "VibraRise".

The robot drives onto a carpet...

Roborock S7 drives onto a carpet

...and lifts the mopping plate.

Roborock S7 lifts the mop as it drives onto a carpet, thanks to the VibraRise technology

It worked perfectly well in our test, but only on low pile carpets.

As the robot lifts the mopping plate only by approx. 4-5 mm., the technology doesn’t work that well on high-pile carpets.

However, it’s not a big deal if the "lifted" mop slightly streaks the top of the high pile carpet:

  • The robot doesn’t apply the 580-gram extra pressure when it lifts the mop.
  • The water supply is deactivated.
  • The vibration stops.

Thus, it’s not comparable to the conventional mopping intensity, even if the wet mop slightly touches the carpet fibres of a high pile carpet.

You can also set up a no-mop zone around the carpet if you prefer that.

Another advantage of the VibraRise technology is that once the robot vacuum finished its cleaning trip, it lifts the mop and makes its way to the charging dock.

That means that the robot won’t drag the mopping pad over the already cleaned areas again.

The wet mop also stays in the raised position at the docking station.

It won’t touch the floor, so that you won’t need a floor mat, either. And you don’t have to remove the mop immediately after cleaning.

It’s a super handy feature. Chapeau to Roborock here!

Sonic Mopping - The Vibrating mopping function

The mopping module has a separate motor, which creates the vibration of the mopping plate (similar to an electric toothbrush).

A close-up of the vibration motor for Roborock S7's mopping plate.

The Roborock’s Sonic Mopping vibrating mopping function

It simulates "scrubbing movements", which leads to much better mopping results!

The vibration intensity varies depending on the water intensity level:

  • “Low": 1650 vibrations / minute
  • “Medium": 2300 vibrations / minute
  • "High": 3000 vibrations / minute

That means you’ll always have the suitable cleaning mode at hand - no matter how dirty your floors are.

Check Amazon*

„Deep Cleaning" Mode

You can also activate the "Deep Cleaning" in the mobile app.

Then the robot switches off the suction motor, and it only mops your floors.

And the Roborock S7 runs each path twice. It also decreases the distances between the tracks so that they overlap.

Deep Cleaning Mode

Standard Mode

The standard mopping mode in the mobile app

An advantage: The mopping result improves significantly in the "Deep Cleaning" mode.

Furthermore, the overlapping of the tracks means that the wheels won’t cause any streaks.

FYI: Since the robot vacuum turns off the suction motor in "Deep Cleaning mode", it hardly decreases the battery runtime. Thus, it can also mop larger areas at once.

The Fluffy Washable Mop

They also improved the microfiber mop.

Close-up of the Roborock S7 mop

It extends over the entire width of the mopping plate.

The mop also quickly absorbs the water thanks to the fluffy fabric.

Thus, the robot vacuum cleaner creates an even mopping track.

The mop is reusable. You should wash it in the washing machine at 40 degrees after each mopping trip.

Controlling the Water Intensity via the Mobile App

You can choose between 4 different levels for the water intensity via the mobile phone app.

Your advantage: You can set it for each room individually.

This way, the robot vacuum can mop the delicate laminate flooring in the living room with less water and the tiles in the kitchen with a lot of water.

How Good is the Mopping Result?

The mopping result is much better than with a conventional robot vacuum / mop hybrid.

("Conventional" mopping robot vacuums only pull a wet cloth behind.)

Roborock S7 mops the study

The Roborock S7 mops a hard floor in the study

The vibrating mopping plate (sonic mopping technology) plays a significant role in the Roborock S7’s good mopping performance.

The vibrations of the mopping plate simulate "scrubbing movements". With this, the robot vacuum can even remove the most stubborn stains.

The "Deep Clean Mode", the increased weight (~5 kg) and the additional contact pressure (approx. 580 grams) also contribute to a significantly better mopping result.

You’ll see that when you take a closer look at the mop after the mopping trip...

Holding the dirty Roborock S7 mop in the hand

Long story short: The improvements pay off! The Roborock S7 is one of the best "robot vacuums with mopping function" on the market.

If you're big on the mopping function, the Roborock S7 is the way to go.

Does the device put an end to mopping by hand?

Unfortunately, not yet.

Even though the Roborock S7 offers numerous innovations with the mopping function, the result doesn't come close to mopping by hand.

The weight is still too low (despite the improvements) to remove stains that have dried for days.

But keep in mind that stains that have dried for days are also tricky to remove by hand...

It reliably removes light stains (e.g. coffee or fresh wine stains), dirt and dust residues, though.

Thus, the Roborock S7 provides significantly more cleanliness in your home.

Especially for allergy sufferers, the significantly improved mopping function is a great advantage. So if you are allergic to dust, the Roborock S7 would be a good choice!

Read this detailed review " Robot Vacuums for Allergies " if you want to find out more about this topic.

P.S.: Do you want to get more out of the mopping function? You can quickly improve the mopping result with our tips and tricks.

Tips & Tricks to Improve the Mopping Function

Create a Good Starting Point

Before you send the Roborock S7 out to mop for the first time, you should wet clean your home very thoroughly by hand.

That way, the Roborock S7 has the best conditions for its first mopping trip.

Now you can let the robot mop your apartment every other day.

Then you’ll always maintain a certain "basic level" of cleanliness.

It’s entirely sufficient if you mop your home every few weeks by hand.

Always use a Fresh Mop Pad

We recommend washing the mop after each mopping in the washing machine at 40 degrees (with your dirty laundry).

The cleaner the mop, the better the mopping result.

Unfortunately, the delivery scope includes only one mop.

But: You can buy extra mops on the Internet.

We also have a total of 3 mops. Thus, we always have a clean one at hand.

Wet the Mop Before You Start Cleaning

We wet our mop thoroughly before we start cleaning.

Dampening the Roborock S7's mop under the tap before the cleaning trip starts

This way, you make sure that the mop is wet from the first moment of the cleaning run...

...so that the robot creates an even mopping trace.

Use Special Cleaning Agents

First of all, Roborock doesn’t recommend using special cleaners. According to the manufacturer, this can damage the water container.

So if you put special cleaners (designed for mopping robots) in the water container, you do so at your own risk.

However, we have had excellent experiences with our vacuum-mopping robot (Roborock S5 Max). Adding special cleaning agents improves the mopping result by a bit.

Small tip: Alternatively, you can also put some cleaner onto the mop or directly on the floor.

Auto-Empty Dock

The auto-empty dock of the Roborock S7 from the frontRoborock fans always enviously looked at the competition... Because other premium manufacturers already had them.

We're talking about an auto-empty dock.

The Roborock S7 puts an end to this! The self-emptying dustbin is another highlight of the robot vacuum cleaner.

It’ll be available in the UK in two colours (black and white) in Autumn 2021.

The way it works is pretty straightforward.

Your little housekeeper returns to the docking station to charge the battery once it finished cleaning.

The station simultaneously extracts the contents of the mobile dust container during this process.

Self-emptying process of the Roborock S7’s mobile dust container.

So far, so good. But Roborock wouldn't be Roborock if they wouldn’t add a little extra ?.

The unique feature here is that you can use either disposable or reusable dust bags for the emptying station.

No disposable bags, which is good for your wallet and the environment.

We constantly complained about this with the current models of the competition (with disposable dust bags)...

As an allergy sufferer, you can still use a disposable bag in the emptying station if you don't want to empty and clean the reusable bag.

What an improvement. Chapeau, Roborock UK!

The auto-empty dock is one more step towards fully automated cleaning.

You won’t have to empty the mobile dust container anymore.

The large dust container in the auto-empty station only needs your attention every few weeks.

That's it.

We are (or rather - have become) big fans of the emptying station. This feature is one of the main reasons to send our Roborock S5 Max in its well-deserved retirement ?.

Take a look at this detailed review if you want to learn more about Robot vacuums with self-emptying base.

Control and Connectivity (Mobile App and Co.)

Operation with buttons

You can control the Roborock S7 with three buttons that are on top of the robot vacuum.

(1) Power button - start/stop a cleaning process

(2) Home button - Return to charging station

(3) Spot cleaning / Child lock

Close up of the Roborock S7’s control buttons

Especially the child lock button (3) is pretty exciting. If you press it for 3 seconds, you - or rather, your children - can’t control the robot vacuum with the buttons anymore.

Therefore, children or pets (e.g. cats) can’t "accidentally" interrupt the cleaning process :)

Mobile App

Your Roborock S7 becomes "smart" by using a mobile phone app.

You can choose between two options:

Both apps are identical in terms of functionality.

Roborock App

Roborock App in the App Store

Xiaomi Home

Xiaomi Home app available for download in the App Store.

We recommend the Xiaomi Home App if you have several smart home devices from Xiaomi in use. This way, you can control all devices via one app.

The fact that Roborock releases bug fixes, updates, etc. faster speaks for the in-house Roborock app.


You have to do the following steps to set up the app:

  • Download the app from the App Store.
  • Sign up with an email address and password.
  • Add your Roborock S7 via the menu item "Add device".
  • Connect it to the WiFi.
  • Done. Now you can start the first cleaning trip.

The setup of the mobile app went 100% smoothly. The app was ready to go after about 3 minutes ?

Check Amazon*

Functionality of the Mobile App

The mobile app offers numerous functions and settings, making daily floor cleaning extremely easy.

The following functions are available in the mobile app:

Live Mapping

You can see your robot vacuum live in the mobile app.

Roborock S7's route in the mobile app

The white lines show the area that’s already clean.

The “hazy” lines show where the Roborock S7 also mopped the floor.

Water Intensity/Suction Power per Room

You can set the water intensity or the suction power individually for each room.

Setting the water intensity or suction power individually per room in the Roborock App.

Another special feature of the Roborock S7: The vibration speed of the mopping plate also depends on the water intensity level:

  • “Low": 1650 vibrations / minute
  • “Medium": 2300 vibrations / minute
  • "High": 3000 vibrations / minute

Activating "Deep cleaning" (For Mopping only)

Here, the Roborock S7 turns off the suction motor and only mops your home...

...and that very "thoroughly".

The Roborock S7 will mop each path twice. It also reduces the distances between the mopping paths.

Activating Deep Cleaning in the mobile app

Single Room Cleaning

You don't always want the robot to vacuum/mop the entire apartment.

You can also use the "Single Room Cleaning" feature to let Roborock clean only one specific room.

Our kitchen usually looks pretty dirty after cooking. So our little housekeeper has to clean the kitchen almost every day.

Spot Cleaning

Did you drop some chips?

No problem! You can simply define a specific spot in the map that the robot vacuum should clean.

Defining a specific cleaning spot in the Roborock S7 mobile app.

Setting up No-Go Zones and No-Mop Zones

You can also define areas where you don’t want the Roborock S7 to vacuum or mop.

That’s very practical: You can zoom in on the map, making it much easier to "draw" the areas.

Setting up No-Go Zones and No-Mop Zones in the Roborock App.

Saving up to 4 Maps

The Roborock S7 can save up to 4 maps. That makes it very suitable for homes with several floors.

Separate / Merge Rooms

The robot vacuum automatically separates rooms during the map creation. That worked flawlessly in our apartment.

Nevertheless, you can also separate or merge rooms manually if you want.

Setting up the Cleaning Order

You can also set the order of the rooms where the robot should clean (for example, bedroom first, then the living room, then the kitchen, etc.).

Setting the cleaning order of the rooms in the app

Carpet Turbo

The Roborock S7 will switch to the highest cleaning mode ("Max") every time it drives onto a carpet if you activate this setting.

Dealing with Carpets when the Mopping Function is Activated

You can choose how the vacuum-mop robot should handle the carpets in the mobile app. The following options are available:

  • Raising the mopping plate
  • Driving onto the carpet
  • Avoid the carpet

If the Roborock S7 mistakenly marks an area as a "carpet" on the map, you can edit that as well.

Timer Function

Here you can set when you want the Roborock S7 to clean your home.

Setting the exact day and time of the cleaning trip in the Roborock App


Under the menu item "Maintenance", you can check the condition of the individual spare parts. You can also see valuable cleaning/maintenance tips here.

Maintenance information for each spare part in the Roborock S7 App.

Room Naming

You can name the individual rooms in your apartment.

Voice Output

The Roborock S7 likes to share what it’s up to, "Start cleaning", "Cleaning finished, going back to the dock", etc.

You can switch off the voice output or adjust the volume in the app.

Language Selection

You can choose from many different languages (English, French, Chinese, German etc.)

Remote Control

You can also control the Roborock S7 with a kind of "joystick". It’s pretty entertaining, but we haven’t found an actual use for it yet.

Conclusion on the App

We'll make this quick and easy.

The app is currently the best on the market.

The range of functions is outstanding.

The operation is effortless.

But more importantly, the app runs smoothly and reliably - just like Swiss clockwork.

No bugs, no translation errors, no crashes.

In other words, the mobile app is really good, and no other app can hold a candle to it.

It certainly deserves our highest possible score!

Check Amazon*

Voice Control with Alexa, Google Assistant and Siri

You can control the Roborock S7 via voice commands, too.

It works with Amazon's Alexa, Google Home Assistant and Apple Siri.

We tested the voice control with Alexa (Roborock Home Skill).

It worked wonderfully.

You can use the following commands:

You can save up to 4 Maps

Map creation

You’ve unpacked the robot vacuum cleaner.

The battery is full.

Now the robot vacuum is ready for its first cleaning trip.

It will also create a map of your apartment.

You have to activate the "Save map" option in the app first.

You can see how the robot creates the map of the apartment live in the mobile app.

You can follow the map creation process live in the app

Tip: Please tidy up your apartment and open all doors before the first trip so that the robot vacuum cleaner can easily access every room.

The map in the mobile appYou’ll have access to the saved map as soon as the Roborock S7 docks at the Charging Station.

Special feature: Carpets are "shaded" on the map. That way, they are clearly visible and can serve as landmarks on the map.

If you move your furniture (e.g. the couch), the Roborock S7 will detect that during the next cleaning cycle and updates the map "in real-time".

4 Maps for 4 Floors

The Roborock S7 can save multiple maps - a total of 4 maps to be precise.

That makes the robot vacuum cleaner ideal for larger houses/apartments with several floors.

You have to do the following steps to create the map for the second floor:

  • Carry the Roborock S7 and the charging station to the second floor.
  • Start the cleaning process.
  • The robot vacuum will create the map of the second floor.
  • The robot vacuum cleaner saves the map as soon as it returns to the charging station.
  • Now you can edit it as you wish (separate / merge rooms, set up no-go zones, etc.).

Once the robot has created the second map, you just have to carry the robot vacuum itself (without the charging dock) to the second floor and start cleaning. It will automatically pull up the correct map.

When the robot vacuum finished cleaning the second floor, it’ll return to where you dropped it off and wait for you to carry it down.

Floor cleaning can be so easy ?


Roborock relies on laser navigation (Lidar sensors).

The robot vacuum scans the room with a unique laser distance sensor (LDS). With this, the little housekeeper always knows where it’s at and where it has to go next.

The advantage: The robot vacuum can easily clean your apartment in absolute darkness, too.

It's remarkable how well the Roborock S7's navigation works.

It drives around the apartment without any problems.



And fast. (The Roborock S7 takes about 1 minute for 1 m²!).

Showing the navigation of Roborock S7 on the map

Long story short: The navigation is top-notch!

Dealing with Obstacles

The Roborock S7 also avoids „large“ obstacles. The vacuum-mopping robot is super gentle (almost too gentle) with furnishings.

It marks larger objects (doors (1), cupboards (2), table legs (3), etc.) on the map and avoids them during its cleaning trip.

Showing the map of the apartment in the Roborock App

The bumper comes into action now and then. But that’s quite normal - that's what it's here for ;)

Then the robot vacuum slightly nudges the object, recognises that there is an obstacle and looks for a way around it.

It doesn’t recognise smaller objects (e.g. socks, shoelaces, etc.) as obstacles.

Therefore, you should remove them before the robot’s cleaning trip.

If you’re big on this feature for navigation, you should look at our review of the Roborock S7 MaxV Ultra and the Roborock S6 MaxV review.

In our experience, you’ll only need the "automatic obstacle detection of smaller objects" in very chaotic households. We can do without it because we clean up the floor as much as possible before cleaning. But that’s relatively normal since you can’t clean a floor that’s covered with things.

Overcoming Thresholds

Roborock S7 can easily overcome higher door thresholds (~ approx. 1.9 cm).

Roborock S7 climbs a higher door threshold

The robot has an intelligent approach here.

First, it drives to the door threshold straight. If that doesn’t work, the robot vacuum cleaner turns 90 degrees and tries to approach it again at this angle.

In our experience, conventional doorsteps and carpets don’t pose a threat to the Roborock S7.

Your doorsteps are higher than ~1.9 cm?

Don't worry. You don't have to do without the robot vacuum.

You can make your home "robot vacuum-friendly" with special doorstep ramps*.

Read more about this topic in this review: "Robot Vacuums for High Thresholds".

The Battery Life

The Roborock S7 has a 5200mAh battery.

The robot vacuum can clean your home for up to 3 hours at a time (maximum cleaning area: 300 m²) in the lowest power mode ("Quiet") with this battery.

Of course, if you use the vibrating mopping function (sonic mopping), the battery won’t last that long.

A full charge can take up to 6 hours (when the battery is almost empty).

But the robot vacuum also has a reliable "Charge & Resume" function. Thanks to this, the robot vacuum drives to the docking station to charge the battery whenever it runs low. Then it continues cleaning at the same point where it had to interrupt its trip.

The long-lasting battery, super-fast navigation and Recharge & Resume features make the S7 perfect for large apartments/houses.

Another advantage: If you use the "thorough cleaning mode" (only available for mopping), it won’t use much of the battery (because the suction motor is turned off).

Sound Level

We also measured the sound level of the Roborock S7.

The volume depends mainly on the cleaning mode.

  • Quiet: 59 dB
  • Balanced: 60 dB
  • Turbo: 64 dB
  • Max: 69 dB

Measuring Roborock S7's volume with a mobile app

The Roborock S7 was pretty quiet in the two lower power settings (Quiet and Balanced).

You can easily watch a movie or have a conversation in the same room.

The volume was noticeably louder in "Turbo" and "Max" mode (as expected).

But the best part of a robot vacuum is that it can clean the apartment in your absence :)

We only use the "Balanced Mode" in our apartment (hard floors, no children, no pets). This setting ensures a perfect cleaning result since the robot vacuum automatically increases the suction power when driving over a carpet.

P.S.: Another advantage: The vibrating mopping function is very quiet (almost inaudible). This was a pleasant surprise because the Deebot OZMO T8 AIVI, for example, was quite loud.

That’s the absolute icing on the cake.

Design, Dimensions & Quality

The Robot Vacuum Cleaner

The robot vacuum itself has a round shape - as usual from Roborock UK.

It weighs 4.7 kg, has a height of 9.65 cm (3.8 inches) and a diameter of 35 cm (13.7 inches).

The Roborock S7 also stays below the “magic limit” of 10 cm (3,9 inches) height. Thus, the robot vacuum fits under most heaters, beds, etc.

Only robot vacuums without a laser navigation tower have a flatter design. However, these models have many other disadvantages, which is why they are relatively rare.

The robot vacuum is available in the UK in two colours: white and black.

From a visual point of view, the Roborock S7 doesn’t differ much from its predecessors.

But it does have a few unique features in stock.

A close-up of the top of the Roborock S7

Firstly, the LED status light. It indicates what the robot vacuum is currently doing:

  • White=Vacuuming
  • Blue=Mopping
  • Status when charging the battery (blue = battery is charging, green = battery is full)

This is quite handy, as you can quickly see the robot’s status without using the app.

Furthermore, you can also see wave-like design elements around the laser tower. These probably represent the pulsating mopping plate (sonic mopping).

That’s a cool effect.

The upper side is made of plastic and has a matte finish. The appearance looks quite like glass.

You get a glimpse into the inner workings of the robot vacuum if you open the lid (which is surrounded by a silver frame).

You can see a dust container, for example. You can remove it with a handle for emptying.

The bottom also looks very similar to the previous models but has one or two small changes.

Close up of the Roborock S7's underside

The main brush is made of rubber. That prevents hair from wrapping around the brush (we’ll talk more about that in the chapter "Roborock S7 for hair").

The housing of the brush has also changed. It has a "swinging" installation now.

With this, the robot vacuum can optimally adapt to the surface and picks up dirt more effectively.

You’ll see most of the changes in the design at the back.

The mopping plate and the water tank are now permanently installed in the device.

The new arrangement simplifies handling immensely.

You can easily remove and replace the mopping plate and water tank.

To sum up:

The quality and design of the Roborock S7 are impeccable - as usual.

There's nothing to complain about here.

Charging Dock / Auto-Empty Dock

The Docking Station

The charging dock has the following dimensions: Height: 10 cm (3.9 inches) x width: 12.7 cm (5 inches).

Measuring the height of the charging dock with a ruler

Thus, the charging dock is relatively small, so that you can put it under a cabinet, for example.

If you take a closer look, you can see two small brushes. They clean the charging contacts when the robot docks at the charging station.

A smart idea ?.

Charging Contacts

The charging station doesn’t have a cable management system in the back.

That’s a minor drawback.

At least they included a cable tie in the delivery scope. With this, you can stow away excess cable.

Another thing: The power cable is relatively short (approx. 1 meter). Thus, you have to place the charging station close to the socket.

Auto-Empty Dock

The auto-empty dock will be available in the UK in Autumn 2021.

This is what we know so far:

  • The emptying station will be available in white and black colour.
  • You can choose between a reusable container or disposable dust bags for the emptying station.
  • and: It looks cool ?.

Of course, we will let you know as soon as we have more information about the self-emptying dustbin.

Delivery Scope and first steps

First Steps

Setting up the Roborock S7 is very simple.

The robot vacuum cleaner is virtually already assembled in its packaging.

You only have to charge the battery.

To do this, place the docking station in a suitable location and put the robot vacuum on it.

Please make sure to leave enough space (left and right min. 50 cm (19.6 inches)).

The charging process can take several hours.

In the meantime, you can download the Roborock App and set it up. We described this process in the chapter "Control (App and co.)".

You're ready to go once the battery is full.

You can start the first cleaning trip in the mobile app (or by pressing the power button on the robot itself).

Delivery Scope

The delivery scope is relatively modest.

  • The robot itself
  • Charging dock incl. power cable
  • Operating manual
  • Mopping plate with a washable mop

The entire delivery scope of the Roborock S7 is on the floor

Spare parts? Accessories? Nope!

You have to buy that separately. That’s too bad. A replacement brush or a second mop would’ve come in quite handy...

You also have to buy the emptying station separately. It should be available in the UK from Autumn 2021.

The Price in the UK

The Roborock S7 is currently only available in the UK without the emptying station.

The robot vacuum’s current RRP is in the higher price segment.

We don’t know the price for the self-emptying dustbin yet.

Whether there will be a somewhat discounted "bundle package" (robot vacuum + emptying station) is also unclear.

Is the higher price justified?

We think so!

The Roborock S7 even looks cheap if you compare it to competitor models with "similar" range of functions (e.g. Ecovacs Deebot T8 AIVI).

However, if you already have a Roborock S6 MaxV or a Roborock S5 Max (both are good devices), then you should think twice if you want to replace them with the Roborock S7.

Conclusion: Is it Worth Buying the Roborock S7?

We reviewed the new Roborock S7... and the robot vacuum won our hearts.

Especially if you’re big on the mopping function, you’ll be thrilled!

The vibrating mopping plate (sonic mopping) ensures an excellent mopping result.

The robot can also lift the mopping plate (that’s a first in 2021). Thus, it won’t pull the wet mop over the carpet.

What an innovative feature.

The self-emptying dustbin for the Roborock S7 will be available in the UK in Autumn 2021. You don’t have to use disposable bags. Instead, you can use the installed dust container that you can empty by hand - also an excellent feature.

No matter where you look, you can hardly stop marvelling.

The Roborock S7 is a true allrounder that leaves nothing to be desired.

We can give it a clear purchase recommendation!

  • How Big is the Water Tank?

    The water tank has a capacity of 0.3 litres.

    A close-up of Roborock S7's water tank

    The Roborock S7 can mop our entire apartment (80 m²) once with maximum water output.

  • Mobile Dust bin

    The Roborock S7’s mobile dust bin has a capacity of 470 ml.

    Roborock S7's dust bin is on the floor.

    Thus, we can vacuum our 80 m² apartment about 5-7 times. Then the container is filled to the brim so that we have to empty it.

    You can open the dust container with a handle and empty it over the dustbin.

    Emptying Roborock S7’s dustbin

    Unfortunately, the robot doesn’t have a dust retention flap. Thus, you have to be more careful when removing and carrying the dirt container.

    You can wash out the dust container under running water.

  • HEPA Filter

    The Roborock S7 has a HEPA filter (also called a high-efficiency submicron particulate filter).

    It’s in a separate chamber.

    Removing the HEPA filter of the Roborock S7

    It’s pretty convenient that the filter is in a separate chamber because now the robot vacuum won’t lose suction power when the dust container is full.

    Another advantage: The filter absorbs dirt more slowly. Therefore, you have to clean/replace it less frequently. That’s also thanks to the fact that the filter is in a separate chamber.

    Especially for allergy sufferers, a HEPA filter is an absolute "must-have" feature in a robot vacuum. It filters out even the smallest dust particles from the air.

    You should clean the HEPA filter regularly. To do this, you should tap out the filter over a bucket first and then wash it under lukewarm water.

    Tapping out the HEPA filter of the Roborock S7 over a trash can.

    Washing the Roborock S7's HEPA filter under running water

    Note: The HEPA filter should dry on the windowsill for approx. 24 hours before you put it back into the robot vacuum cleaner.

  • Is There a Remote Control?

    The Roborock S7 doesn’t come with a remote.

    Thus, you have to control the robot vacuum by using the control buttons on the robot itself or via the smartphone app.

  • You can’t connect it to the WiFi?

    Unfortunately, it doesn’t support 5 GHz WiFi yet.

    If you have a 5 GHz router at home, you should change the router to 2.4 GHz for setting up the app. After the setup, you can switch the Wi-Fi setting back to 5 GHz.

    You also have to give the app all the required permissions (especially "Determine location"). Otherwise, it can’t establish the WiFi connection.

  • Is There a Bumper in the Laser Tower?

    Yes, there are shock sensors (bumpers) in the laser tower.

  • Xiaomi - Is the Chinese Company also involved here?

    The Chinese giant "Xiaomi" has its fingers in the “Roborock-pie”. Thus, Roborock benefits from the size, know-how and financial strength of the Chinese tech giant.

    However, Roborock always emphasises operating as a separate company (and brand) in the market.

  • Main Brush

    Roborock fundamentally revised the main brush of the Roborock S7. It’s the first time that it’s made of rubber. (Reminder: The predecessors always had a brush made of bristles and slats).

    Removing the main brush of Roborock S7

    Now, pet hair or human hair can’t wrap themselves around the brush that easily. That significantly reduces maintenance.

    Furthermore, the main brush also "swings around" in the housing. With this, the brush can move to the left/right and front/back.

    The significant advantage is that the brush can better adapt to special floor conditions and cleans uneven surfaces more thoroughly.

    The manufacturer also states that that reduces the risk that the robot could suck in cables (e.g. phone charging cables).

    A slight disadvantage: Since the brush is made of rubber, you shouldn’t have any sharp objects (e.g. broken glass) lying on the floor. They could damage the brush - even if the rubber is very resistant and robust.

  • Side Brush

    The Roborock S7 has a side brush. It’s also made of rubber and has 5 arms.

    Close-up of the Roborock S7’s side brush

    Note: The side brushes of the S7, S5 Max, S6, S6 MaxV, S50 / 55 and S4 are compatible with each other.

    So if you prefer a side brush made of bristle hair, you can use the side brush of an older model (e.g. Roborock S50).


  • Carpet Detection with Ultrasound

    The Roborock S7 has an ultrasonic sensor.

    A close-up of Roborock S7's ultrasonic sensor.

    It detects carpets...

    ...and whenever the robot drives onto a carpet, it lifts the mopping plate.

    Furthermore, the robot vacuum also marks carpets as a "shaded area" on the map.

    Carpets are shaded areas on the Roborock S7 map

    That’s a great feature of the Roborock S7. It clearly marks the carpet on the map (e.g. for drawing in no-go/no-mop zones).

  • Crash Sensors and Dealing with Chasms

    The Roborock S7 has crash sensors on its underside.

    With these, it reliably avoids chasms.

    We recommend cleaning the crash sensors with a damp cloth at regular intervals.

  • Can my Roborock S7 Clean in Complete Darkness?

    The laser-based navigation doesn’t care whether it is light or dark in your home. The navigation is as reliable, fast and seamless as usual.

  • What is the Suction Power of the Roborock S7 in Pascal (Pa.)?

    The suction power of Roborock S7 is 2500 Pascal (Pa.)

  • How Many Different Suction Levels Does the Roborock S7 Have?

    You can choose from 4 different power settings here (Quiet, Balanced, Turbo and Max), so you’ll always have the proper mode at hand for every kind of dirt.

  • Water Intensity

    You can control the Roborock S7’s water intensity via the app.

    It has 4 different water intensity levels.

  • Is There a Water-Resistant Pad for the Charging Dock to Protect the Floor from the Wet Mop?

    No. But it's also no longer necessary.

    Since the Roborock S7 can raise the mopping plate with its VibraRise technology, the wet mop no longer touches the floor when it docks at the charging station.


  • Are There Marks from the Rollers During Mopping?

    We didn’t see any marks from the rollers when mopping.

  • The Mopping Trace is Very Thin. Is that Normal?

    During the first few mopping trips, the wet trace might be pretty thin. That should improve with time.

    If this doesn’t improve, we recommend piercing the water outlet hole on the water tank very carefully with a thin needle.

    But you should ALWAYS dampen the mop before the robot vacuum starts cleaning. Roborock also recommends that in its manual. With this, the robot will create an even trace from the very beginning of its mopping trip.


  • The Main Differences between the Roborock S7 and Previous Roborock Models (Roborock S6, Roborock S5 Max, Roborock S6 MaxV)

    The Roborock S7 sets itself apart from its predecessors in the following ways:

    • Roborock S7 has a more powerful suction (2500 Pa), which leads to a better cleaning result.
    • Roborock S7 has a vibrating mopping function, which ensures a better mopping result. The previous models only dragged a wet mop behind themselves.
    • Roborock S7 can lift the mop when driving over a carpet. Thus, it won’t drag the wet mop over the carpet.
    • You can buy an emptying station for the Roborock S7 separately
  • The Main Differences Between the Roborock S7 and Ecovacs Models (Deebot OZMO T8 and T8 AIVI)

    Both the Roborock S7 and T8 series (Deebot OZMO T8 and the T8 AIVI) have a vibrating mopping function.

    It worked well in all three models, but the mopping result of the Roborock S7 was a tad better. We think that the higher weight and the more substantial contact pressure contribute to the better mopping result. The vibrating mopping function of the Roborock S7 was also much quieter than that of the T8 models.

    All three models have an emptying station. Unlike the Ecovacs models, the Roborock S7's emptying station doesn’t need disposable dust bags. That point goes to the Roborock S7.

    Furthermore, the Roborock S7 can lift the mopping plate when driving over a carpet (VibraRise). The Ecovacs models don’t have that.

    The Roborock S7 doesn’t have a special obstacle detection function like the Ecovacs Deebot OZMO T8 and T8 AIVI. You have to remove flat objects such as phone charging cables, shoelaces, etc., before cleaning.

    That would be a great new feature for the successor (Roborock S7 Max), right? :)
