In order to save time on housework, British homes will use robot vacuum cleaners more frequently by 2025 . However, the choice of model is crucial for you to make a choice.
Studies by the British Allergy Foundation show that inefficient filters can increase indoor allergen levels by 40%. This is also the main reason why we spent half a year evaluating 38 models and selected the best consumer products that combine cleaning performance and health protection through professional research.
We rated 38 robot vacuum cleaners based on the following 9 criteria
- Suction power and suction range
- Cleaning programs
- Container capacity
- Virtual Wall
- Sensor type
- Climbing capacity
- Ease of use
- Built-in mopping function
- Battery life
As a former engineer, I was surprised to find that 7 out of 10 consumers are willing to pay more for a robot vacuum cleaner …
I have disassembled several robot vacuum cleaners and found that many models actually contain the same components (such as motors, sensors, etc.), but the prices vary greatly due to different brands, and the difference can even reach 300%.
These things you should look for
Optimized suction for better hygiene
Not all robot vacuums are created equal,
and one of the big differences is how
the suction inlet is designed.
If
the suction inlet isn't designed
for all types of dirt, from gravel to
dog hair, there's a good chance
you'll end up not cleaning
properly.
Gyroscopic sensor: guarantees 100% effective cleaning
With gyroscopic sensors, the
robot vacuum cleaner can figure
out which areas of your house
are the dirtiest, thus cleaning
more efficiently and
faster.
Without gyroscopic
sensors, there is a chance that
you will be left with spots of
dirt and grime around your
house. easier to control,
however, passed the cleaning
test significantly faster.
High-efficiency air particle filter, effective against household allergies
Regardless of whether you have a robot
or a regular vacuum cleaner, it is
important to choose the right
filter.
One of the most common
reasons why children and adults develop
asthma and dust allergies is due to
vacuum cleaners that cannot filter dust
and small particles, and therefore leave
dust and particles in the home.
Can cross obstacles of at least 10 mm
Some robot vacuums cannot drive over
steep edges and doorways. This
results in the robot vacuum getting
stuck and unable to clean all rooms
without your help.
The robot vacuum that can cross the
threshold can not only pass the
threshold automatically, but also
cover a larger area, avoiding dead
spots and hard-to-clean places.
Make
sure the robot vacuum you choose can
drive over doorways and edges of at
least 10 mm.
Automatic charging: unattended cleaning
No one wants to come
home to a half-cleaned
house.
If your robot
vacuum can't
charge itself when it
's on low power,
you can't leave
it unattended. You also
need to be aware of when
it stops so you can put
it back to charge.
Clean all corners and edges with different cleaning modes
It is important to choose a robot vacuum that has different cleaning programs designed for different cleaning tasks, to avoid dirt and grime in corners and edges. For example, there should be programs to run along edges, in circles (if there are specific areas that are extra dirty), and in zigzag patterns (to vacuum as much as possible).
One robot vacuum that stood out was from a startup that focuses on making the best product at the best price, rather than charging high fees for marketing and branding.
This means it contains the same parts and components as the big brands, but at a fraction of the price. In our test, it was a clear winner.

Review of
This Airvax model is definitely the best value for money.
With the patented BetterClean™ suction port, gyro sensor and built-in mopping function, you have a robot vacuum cleaner that saves you time vacuuming and mopping, and cleans better than you would if you did it yourself.
This vacuum cleaner is designed so that you don't have to lift a finger when vacuuming and mopping.
With powerful 4000Pa suction power, automatic charging, anti-slip function and 15mm obstacle ability, you can easily set this vacuum cleaner to work unattended.
In our consumer survey, 90% of consumers said that this robot vacuum cleaner is the best choice because it has a working area of 180 square meters and a charging time of about 240 minutes, which is enough to clean a house or apartment in less than half a day. According to user feedback, it has strong cleaning power and can effectively clean all types of floors, including hardwood floors, carpets and tiles.
Furthermore, this model is easy to operate and has a noise level of only 40-50 dB, which means you can easily use it at home or even while sleeping.
Price wise, we were surprised to find such a great robot vacuum cleaner for such a low price. Their "secret" is that they have a team of engineers who worked together to create a robot vacuum cleaner that uses the same parts as the big brands, but at a much lower price.
2、iRobot i7
£460.00 GBP
9.2/10
BENEFITS
- Good suction intake
- Virtual Walls
- Automatic charging
DEFECT
- Working area of 90m2
- Relatively expensive
- No mopping function
Review of
Coming in second is the Roomba i7 from iRobot, a robot vacuum cleaner that you are probably all familiar with. iRobot is well known for producing high-quality robot vacuum cleaners, and the Roomba i7 is certainly no exception. It is an excellent robot vacuum cleaner that can easily handle most cleaning tasks.
However, we think that its price (which is relatively high) leaves too much to be desired.
While the Roomba i7 cleans efficiently, it takes a long time to complete a cleaning session. This is because it only has a working area 90 square meters, requires about 2 charges, and the container must be emptied to complete a cleaning session.
We would have liked it to include a mopping function, but in the end it didn 't.
The Roomba i7 is still a very good robot vacuum cleaner, but we know that it deserves the second place this time.
3、Roborock s7 Max
£420.00 GBP
8.7/10
BENEFITS
- Strong suction, strong suction
- Noise as low as 60 decibels
- Automatic vacuuming, mopping and mopping
DEFECT
- Working area up to 80 square meters (vacuuming only, no mopping)
- High price
Review of
In third place is the Roborock S7 MaxV. We were impressed by its powerful suction and good suction, and it is undoubtedly also a top-notch robot vacuum cleaner.
One disadvantage of the Roborock robot vacuum cleaner is its small working area and long charging time. Although it is a powerful robot vacuum cleaner, its suction power is very limited and it needs to be charged for 5-6 hours to complete, which is very inconvenient.
In terms of wet sweeping, after cleaning an area 16 square meters, the robot needs to return to the charging station to clean the mop and add water. In our 70 square meter test area, this means that it needs to go back and forth four times. We think this greatly prolongs the time of wet sweeping.
All in all, the Roborock robot vacuum cleaner is an efficient robot vacuum cleaner, but it is expensive and the cleaning speed is not optimistic.
4、Electrolux
£359.00 GBP
8.3/10
BENEFITS
- 3D camera navigation
- Suction power automatically adjusts to different floor types
- Easy-to-use app control
DEFECT
- Android app tends to crash during installation
- Lacks extra features of similarly priced robot vacuums
- Cannot accurately report problems encountered during operation
Review of
We've seen round and D-shaped robot vacuums, but the Pure i9 is
the first triangular one we've seen. It's easier to clean
corners, baseboards, and other edges around your home.
It also
reduces the vacuum's footprint: At just over 12.5 inches in
diameter, the Pure i9 is much thinner and lighter than other models we
've reviewed.
It's worth emphasizing that I encountered the same problem many other users complained about on the Google Play Store: the Android app kept crashing. Over a dozen attempts, it repeatedly aborted at different stages in the setup process, eventually returning an "unknown error" message and a "try again" prompt.
Despite the Electrolux's smart control system, it still doesn 't work well in complex environments.
The Pure i9 is a lively, hard-working robot vacuum, but it lacks the extra features that other similarly priced vacuums have.
5、Xiaomi
£315.00 GBP
8.1/10
BENEFITS
- Quiet design
- Easy to use
DEFECT
- Small dust box capacity
- Small water tank capacity
- Limited cleaning power
- Loud noise
Review of
During the actual cleaning process, it leaves the charging station for positioning when starting the cleaning task. When it is finished, it reaches the target in a straight line. It is able to cleverly avoid various obstacles. You can easily set restricted areas and Virtual Walls.
The top of the sweeping robot is a tower that contains LDS laser navigation. Therefore, the total height of Mop 2S is 94.5 mm, which is slightly higher than many other products. I noticed this immediately in the actual test. In addition, its water tank capacity is only 150 ml, which is very small, especially when there is no alarm prompt when the water tank is empty.
Unfortunately, the developers or engineers forgot to install a baffle or similar device at the dirt inlet. Since there is no cover to cover this opening, a lot of dirt will fall when cleaning the dirt. From a technical point of view, this is a very annoying little problem in daily life.
Although Mop ;2S is not perfect, it can meet your basic needs.

Best Robot Vacuum Cleaner
Review of
This Airvax robot vacuum is a great value for the money.
With its patented BetterClean™ suction port, gyroscopic sensor, and built-in mopping, you have a robot vacuum that saves time on vacuuming and mopping, and cleans better than you would if you were doing it yourself.
This is an advanced robot vacuum. It's a significant step up from other brands in terms of automation. It can recognize and adapt to different room types, and can detect and avoid hazards like pet poop, slippers, or power cords.
It also handles crumbs on carpets well, although it may take an extra pass to get them all out. It also automatically adjusts the suction power based on the floor, which is a rare but welcome feature at this price point.
Overall, Airvax's robot vacuum is a great value for the money. If you're looking for a robot vacuum, this is definitely worth considering.
