Robot vacuums for thresholds in comparison

Last updated: 31.12.2023 Reading time: 16 Min.

A robot vacuum makes household cleaning much more manageable. However, high thresholds can thwart these plans. Doorsteps of 2 to 3 cm (0.8 - 1.2 inches) height are quite common, especially in old flats.

Not all robotic vacuum cleaners can overcome such heights easily.

But don't worry: there are many good robot vacuums in the UK that can overcome high doorsteps.

In this review, you will find out which models do well, and we’ll also tell you what you can do if the doorstep is too high for your robot vacuum.

Another groundbreaking feature is the auto-mop lifting function, new to Ecovacs. 

The mops can lift up to 4 mm when the vacuum moves over a carpet.

This allows for a seamless transition from hard floors to carpets in one cleaning cycle. 🧹

With an impressive suction power of 6000 Pascal, the Deebot T20 Omni doesn't just clean; it excels on both hard floors and carpets. 

To make things even easier, it comes with an integrated voice assistant, "YIKO".

It recognises a variety of voice commands, making the control of the device a breeze.

The all-in-one Omni station is the cherry on top, automating multiple cleaning tasks, saving you time and effort. 

However, it's not all perfect: 

  • The size of the Omni station is quite large
  • There are a few bugs in the mobile app
  • The mobile dust container is on the smaller side.

In summary, the Ecovacs Deebot T20 Omni is a comprehensive, high-performing package. 

It's not just a robot that cleans – with its climbing ability and range of innovative features, it's a top contender in the robot vacuum market.

Ecovacs Deebot X1 OMNI

Luxury Robot Vacuum-Mop Hybrid (designed by Jacob Jensen)

Numerous premium features leave nothing to be desired with this Ecovacs model. 🎉

At first glance, you immediately notice the robot’s unique and attractive design. 👀 

And this is no coincidence because Jacob Jensen (famous Danish industrial design studio) is responsible for its look.

Top features of the Deebot X1 OMNI

But it's not just the look of the premium vacuum mopping robot that is impressive. The Ecovacs Deebot X1 OMNI is packed with top features:

  • Emptying station
  • Rotating mopping pads
  • Washing station for the mop cloths 
  • Obstacle detection
  • Integrated voice assistant ("Ok Yiko")
  • …and more!

However, the numerous functions come at a price: this luxury robot is certainly not for bargain hunters... 💸

Mopping ability

The Ecovacs Deebot X1 Omni has many highlights. One of them is its mopping capabilities. 💧

Let’s have a look at the role the station plays in the cleaning process.

After a predetermined interval (10, 15 or 25 minutes), the two mopping pads are wrung out and rinsed at the station.

The Ecovacs Deebot X1 OMNI clean and dirty water tanks are held up.

The benefit here is that your floors are always cleaned with freshly rinsed mops. The collected dirt ends up in the dirty water tank (and not on your floors).

Furthermore, the mobile water tank is refilled at the multifunction station.

So you are spared this (annoying) task as well.

The two mopping pads rotate in opposite directions, creating a "scrubbing effect". This results in a more thorough cleaning of your home. 🧼

And don't forget: when the job is done, the two pads are blown dry at the station (with hot air). 🍃

The two Ecovacs Deebot X1 OMNI mopping pads are seen from below.

All these functions together mean that the wet floor cleaning process runs almost completely independently, so you can sit back and relax. 🏖️

And the mopping performance also impressed us. 👇 

(Even if stubborn, dried-in stains take a bit more effort).

The combination of an impressive mopping ability and a huge range of other premium features makes the Deebot X1 a compelling option.

Although that’s only if you have the necessary funds: because the price will set you back a bit... 💸

functions of the ultra station

Essentially, it makes daily cleaning mostly hands-off. ✋🏻

It's evident that the makers have taken the best parts of their older models and added some neat improvements.

Highlights include a new way to dry the mop, an improved brush system, better obstacle detection, and two mop settings for a thorough clean.

This model feels more like a polished version of the previous ones rather than a brand-new invention.

During our tests, its wiping function worked extremely well. 🧽

Its strong suction was commendable too.

The device also showcased good navigation skills, especially in obstacle detection.

On the downside, its side brush could be better on carpets and edges, and the use of throwaway dust bags seems a bit old-fashioned.

Plus, it's on the pricier side. 🤑

So, if you're after the latest in robot cleaning and don't mind the cost, this is a great pick.

But if you're looking to save a bit, considering the slightly older S7 series might be a good idea.

How do robotic vacuum cleaners cope with high doorsteps?

The manufacturers realised that this problem often occurs. Thus, they redesigned the latest robotic vacuum cleaners so they can handle high doorsteps better.

They put rollers on the bottom side of the robot vacuum.

Close-up of the rollers of a robot vacuum

With these special rollers, modern robot vacuums can easily overcome typical door thresholds.

But even these rollers don’t work wonders...

Doorstep / Threshold Ramps - the solution when doorsteps are too high (> 2.3 cm / 9 inches))

Even the greatest "climber" among the robot vacuums can’t overcome a door threshold of approx. 2.3 - 2.4 cm (~ 0.9 inches).

But what if your doorsteps are higher than that?

Some flats in old buildings have extremely high thresholds (sometimes 2.5 - 3 cm (1 - 1.2 inches) and higher).

That’s not the end of the world. There’s a solution to this problem: A special robot vacuum doorstep / threshold ramp.

A robot vacuum drives over a threshold ramp for vacuum robots into the next room.

You can build a doorstep ramp yourself - depending on your craftsmanship - or just buy one online* on Amazon UK.

PS: This will also make your flat "barrier-free" and thus wheelchair-, walker- or pram-friendly. High thresholds also won’t be typical "tripping hazards" anymore. That ensures more safety in your home.

There are a few features to consider when choosing a robot vacuum doorstep ramp:

  • You have the choice between a "fixed" ramp construction or a ramp that you can put down shortly before the vacuum starts cleaning and remove it afterwards.
  • Make sure that the ramp matches the colour of your floor.
  • If you have very high door thresholds, the ramp should have the smallest possible inclination (the ramp must be longer). The robot vacuum may not be able to drive up the ramp if it’s very steep.
  • If it’s a fixed ramp construction, you have to pay attention that the ramp on the side where the door opens can’t be higher than the threshold. Otherwise, you won’t be able to open the door.
  • With very high thresholds (> 3 cm), you may need a ramp from both sides. The robotic vacuum may not descend the threshold because it sees it like a precipice.
A small tip: You can avoid that by covering the crash sensors with opaque adhesive tape. But be careful: you can’t have "real" precipices (e.g. stairs) in your home then. That wouldn’t end well for your household helper.

Solution No. 1: Buy a robot vacuum doorstep / threshold ramp

Not all people are skilled craftsmen and can build a robot vacuum doorstep ramp themselves.

It’s not necessary.

You can buy doorstep ramps in all shapes and colours on Amazon in the UK.

Rubber ramp

You can conveniently purchase a corresponding rubber ramp on the Internet (buy here from Amazon* UK).

Robot Vacuum thresholds ramps made of rubber lie in front of a high threshold.


  • Very slip-resistant. You won’t have to nail the rubber ramp to the floor or screw it down in any other way.
  • Flexibility. You can leave the ramp permanently in place or put it away after each cleaning.
  • Low wear and tear and, therefore, long-lasting


  • Rubber optics may not appeal to everyone’s taste

Rubber Threshold Ramp*

Aluminium ramp:

You can also buy metal ramps online* for little money on Amazon UK.

But you have to screw these to the floor.

If you don’t want to do that, you can also use self-adhesive ramps.

These ramps are available in different colours. You’ll find a matching style for sure.


  • Cheap
  • No craftsmanship skills required


  • Visually not appealing

Special robot vacuum doorstep ramp made of wood (customised)

If you want a high-quality ramp, you can also buy a customised robot vacuum doorstep ramp made of wood.

You can choose the wood type and colour.

The ramps are manufactured in Germany according to your needs and are of very high quality.


  • Visually not appealingIndividual customisation. They will adjust the ramp according to your living situation.
  • Very high-quality workmanship
  • Regional and sustainable manufacturing
  • Beautiful look (matching your floor)


  • Quite Expensive

Solution No. 2: Build your own robot vacuum doorstep ramp

If you are good at handicrafts, you can build a robot vacuum doorstep ramp yourself.

Wood is very suitable because you can buy it in almost every DIY store for little money and it looks very nice. You can also choose the best (colour-wise) matching type of wood (depending on your floor’s colour and condition).

Please measure the door threshold’s height and width in advance.

Then you can cut the wood to the appropriate length/height and sand it down.

Please make sure that the angle of inclination of your ramp is not too high. Otherwise, your robot vacuum will have a hard time driving onto the ramp.

Once you built the ramp, you can apply a wood preservative. That’ll keep the wood in good condition for as long as possible. It won’t wear out too quickly either.

Purchase advice: What should I consider when buying a robot vacuum for thresholds?

A robot vacuum’s threshold overcomming isn’t the only criterion

If you buy a robot vac only because it has the "best climbing performance", you exclude many excellent models from the beginning.

Ultimately, however, the robot vacuum’s main task is to clean your home in the best way possible.

So if you focus too much on just one criterion, you may have to go for a model with a bad price-performance ratio or make unnecessary compromises.

If your favourite robotic vacuum cleaner has problems overcoming thresholds, you can use a door threshold ramp (buy it or build it). That’ll solve the problem once and for all.

Measure your doorstep beforehand

You should measure the threshold precisely with a conventional ruler before buying.

Measuring the door threshold with a ruler.

A sense of proportion won’t do the job. Please be very precise. Differences in just a few millimetres can be decisive.

Are the door thresholds rounded, or do they have a 90-degree edge?

We always test a robot vacuums on 90-degree edges. That way, we can maintain the necessary objectivity in our tests.

But many doorsteps have rounded edges due to wear.

A robot vacuum’s climbing performance may improve by 1-2 millimetres with rounded edges.

Just give it a try!

You've already chosen a model, but you're not 100% sure if the robot vac can handle high doorsteps?

That’s our advice: Just give it a try!

Every living situation is different. Sometimes robot vacuums simply cope better with some doorsteps than others because they are round or for other reasons.

Best Robot vacuums for high thresholds in the UK - Our Conclusion

High doorsteps can be a show-stopper for your robot vacuum.

The robotic vacuum cleaner simply stops if it can’t cross a threshold, and you’ll have to carry it to the next room.

That’s not what we’d call home automation.

Fortunately, manufacturers have recognised this problem. There are excellent robot vacuum cleaners for high doorsteps of up to 2.3 cm (9 inches) in the UK these days. Our selection of the best robot vacuums for thresholds gives you a good overview of the models.

If you live in an older flat, it’s quite common that the doorsteps are higher than 3 cm (1.2 inches). Not even the best "climbing master" among the robot vacuums can cope with that.

But don't worry. You don't have to do without a cleaning robot.

With "robot vacuum" doorstep / threshold ramps, you make your home accessible for the robot, so it can move effortlessly from room to room.
