Suction test on a hardwood floor
First, the iRobot Roomba i7 Plus had to deal with dirt on the laminate floor.
![Overview table of Roomba i7+'s suction test result on laminate]()
Test result for lentils (removed 43g of 50g | 86 %)
The iRobot Roomba i7 Plus did a great job removing the lentils.
![Roomba i7 during the lentil suction test on a hardwood floor]()
It only left a few lentils in the corners that are difficult to access.
![Dirt remains in the corners during the lentil suction test]()
You can also find a few single lentils on the suction surface.
That’s because the fast-spinning side brush "flung" some light and grainy lentils across the room from time to time.
Test result for oat flakes (removed 45g of 50g | 90 %)
The Roomba i7 (+) also had no trouble with the grainy oat flakes.

The robotic vacuum cleaner reliably removes the dirt.

It left a few flakes in the hard-to-reach corners and single bits in the room, too.

Test result with sand (removed 47g of 50g | 94 %)
The heavy sand is usually very challenging for all robot vacuums.

But the Roomba i7 came out with flying colours and removed a whopping 94% of the sand on the laminate.

iRobot Roomba i7 on carpets – our review
The Roomba i7 Plus doesn’t have an automatic carpet detection function. Thus, it also doesn’t increase the suction power automatically when it drives on a carpet.
It still achieved excellent results in our suction test.
The two rubber rollers rotate in opposite directions so that they thoroughly brush through the carpet. It’ll look super clean after the vacuuming trip.

Higher carpets usually pose a threat to robot vacuums.
But not so with the Roomba i7 Plus.
The robotic vacuum cleaner hardly reached its limits with the lentils (short carpet: 94%, long carpet 98%).
![iRobot Roomba i7 Plus in the lentil suction test on the carpet]()
It's a great result.
The robot vacuum also didn’t have any problems with the oat flakes.
![iRobot Roomba i7 vacuums oat flakes on a carpet]()
It removed 96% of the dirt on both short and high carpet, which leaves nothing to be desired.

The heavy sand on the carpet is the biggest challenge for all robot vacuums.
![iRobot Roomba in the sand suction test on the carpet]()
The Roomba i7+ does a great job here, too, and removes 60% of the sand on the short carpet and 70% on the higher carpet.
![iRobot Roomba i7+ removed half of the scattered sand on the carpet]()
The percentages may seem relatively low at first, but the result is excellent compared to other top models.
The heavy sand sinks deep into the carpet, which is why robot vacuums have a hard time removing it.
Vacuum robots and conventional vacuums / cordless vacuums quickly reach their limits here and don’t score much better.
Plus, you have to keep in mind that our tests are extreme situations.
It’s doubtful that so much sand ends up on your carpet.
Your new household helper also vacuums the home much more frequently, which creates a permanent level of cleanliness.
The robotic vacuum cleans our home almost every day. Dirt can hardly accumulate on carpets or in corners.
The iRobot Roomba i7+’s cleaning performance is entirely sufficient for an average flat.
You will be thrilled!

Cleaning along skirting boards and in corners – our review
The robot vacuum did a great job cleaning along the skirtings and in corners.
![iRobot Roomba i7+ cleans along the skirtings]()
However, the iRobot Roomba i7 obviously can’t achieve a perfect result in corners because of its round shape.
![iRobot Roomba i7+ cleans in a corner]()
Since the Roomba i7+ probably cleans the home several times a week, dirt can hardly accumulate in the corners.
So it’s not a big deal.
iRobot Roomba i7 Plus vs. pet hair and human hair
Most robot vacuums have one combination brush made of bristles and lamellae.
The iRobot has two rubber rollers rotating in opposite directions ("dual brush system") instead.
![Two rubber brushes of the iRobot Roomba i7+ from below]()
Hardly any dirt gets caught in the brushes, thanks to brushes’ material and the opposite rotation.
![Two brushes of the Roomba i7+]()
You can remove the two brushes by a simple "click mechanism" if some dirt (especially pet and human hair) should ever wrap itself around the brushes.
Then you can easily “pull out” the hair.
![Removing hair from the Roomba i7+ brush]()
That reduces maintenance to a minimum, making the iRobot Roomba i7+ particularly suitable for pet owners.
