Homes with several large windows
If you want to cut down on manual cleaning across large panes, compare the permitted dimensions, power supply and work involved in moving the device from one window to another.
Who are these solutions for?
People with windows that are difficult to reach
Check how to install and retrieve the device by following its instructions, particularly the guidance on securing it and its power supply. A domestic robot is not a substitute for the access equipment needed for professional work at height.
Buyers concerned about streaks and frames
If marks, missed corners or touch-ups matter to you, compare the finish you can expect with a manual method that lets you guide each pass directly.
What should you look for before buying?
Robot with battery-powered station
Worth considering: for several large compatible panes, particularly if there isn’t a socket near each window.
Bear in mind: you’ll need to prepare the windows, move the device between panes and maintain the pads.
Mains-powered robot with backup power
Worth considering: if there’s a suitable socket and you can route the cable appropriately near the windows.
Bear in mind: you’ll need to manage the cable and safety cord. On the HOBOT-2S, backup power does not allow cleaning to continue after a power cut.
Squeegee or handheld window vacuum
Worth considering: if you want to control the cleaning on small areas, around frames and when touching up, or if a robot isn’t suitable for your windows.
Bear in mind: you’ll do the cleaning and move the device across the surface yourself.
In September 2026, 60 Millions de consommateurs tested 11 window cleaning robots and found that their cleaning performance varied. So, when choosing, weigh up compatibility and installation requirements against the finish you expect.
| What matters to you | What to check | Who values it most |
|---|---|---|
| Reducing manual work | Dimensions permitted in the instructions; power supply and stated running time for the configuration you choose. | I want to cut down on repeated passes across several large windows without having to guide the tool each time; around 33% of consumers put reducing manual work first. |
| Installation and retrieval | How to secure the device and route the cord according to the instructions; whether a socket is available or how the station works. | When access is awkward, I want to know how to secure and retrieve the device, and what to do in the event of a power cut; around 27% of consumers prioritise installation and securing the device. |
| Streaks and finish | Pad maintenance; access to edges and the option to go over any remaining marks. | If streaks and visible corners concern me, I want to be able to check the results and touch up any areas; nearly 20% of consumers prioritise the finish. |
| Glass compatibility | Measure each pane; check the dimensions and types of glass the model can handle. | I’d rather confirm that each pane is suitable, particularly if the window has dividers or small panes; around 20% of consumers put compatibility first. |
Mistakes to avoid
-
Assuming backup power means the robot can keep cleaning on its own
For the HOBOT-2S, HOBOT says the device stops and gives an alert during a power cut. The backup supply temporarily keeps the robot in place; it doesn’t let it continue cleaning.
In the instructions for the model you choose, distinguish between mains power, the operating battery and backup power. Then check how to retrieve the device after an alert.

Expecting a perfect finish with no touch-ups
60 Millions de consommateurs found that cleaning performance varied among the robots it tested. ECOVACS also warns that a dirty pad can leave a mark when you remove the WINBOT W2.
Have clean pads ready and check how to go over the edges or any remaining marks.
Washing the pads and touching up areas can take time after the robot has finished.
-
Choosing based on the size of the whole window
Dividers can make an individual pane too small for the robot, even if the whole window looks large enough.
Measure each pane and check its dimensions against the instructions for the exact model. Use a manual method for any surfaces that aren’t suitable.
Brands to know when comparing solutions
ECOVACS
The WINBOT range lets you compare power configurations and window dimensions, depending on the model.
- ECOVACS says the W2 PRO OMNI can be powered during cleaning and gives a window size range of 30 × 40 cm to 8 × 2,5 m for the W2S PRO OMNI.
- These manufacturer specifications don’t guarantee the finish on every type of glass. ECOVACS warns that a dirty pad can leave a mark when you remove the WINBOT W2.
HOBOT
The HOBOT-2S is an example of a model with frameless edge detection and backup power.
- HOBOT states that the 2S has 20 minutes of backup power.
- According to HOBOT, the robot stops and gives an alert during a power cut, so you need to remove it promptly. The manufacturer also recommends one dry pass followed by one wet pass.
HUTT
The DDC56 is a twin-disc model worth considering for regular cleaning and its securing features.
- HUTT lists frame detection, an alert and a safety cord for this model.
- The manufacturer’s coverage and cleaning performance figures don’t tell you what finish to expect on every window.
MOVA
You can compare the N1 with other models if your home has both large windows and smaller panes.
- MOVA lists dimensions of 215 × 215 mm and a 120 ml tank for the N1.
- The stated cleaning area depends on the manufacturer’s measurement conditions and doesn’t guarantee the results on every type of glass.
Kärcher
The WV 6 Plus is a semi-automatic handheld option worth comparing if you want to guide the cleaning yourself.
- Kärcher states that the WV 6 Plus offers 100 minutes of runtime and vacuums up water.
- You’ll need to spray, scrub and move the device by hand. The stated runtime isn’t a guarantee of how long it will take to clean a home.

Frequently asked questions
How can I tell if a robot is suitable for my frameless windows or small panes?
Measure each pane and check the instructions for the exact model. ECOVACS gives a range of 30 × 40 cm to 8 × 2,5 m for the WINBOT W2S PRO OMNI and mentions frameless windows. These specifications don’t automatically apply to all robots.
What should I do if the power supply is interrupted during cleaning?
Follow the instructions and make sure you can retrieve the device without putting yourself at risk. For the HOBOT-2S, HOBOT says backup power temporarily keeps the robot in place, but cleaning stops, an alert is triggered and the device must be removed promptly.
Do window cleaning robot pads need maintenance?
Yes. Keeping them clean is important. ECOVACS recommends washing or replacing the WINBOT W2 pad when needed and warns that a dirty pad can leave a mark when you remove the robot. For the HOBOT-2S, HOBOT recommends one dry pass followed by one wet pass, using a freshly changed cloth.
What protection applies after buying from a professional seller in France?
The legal guarantee of conformity applies to new, second-hand and refurbished goods sold by a professional to a consumer. The Ministry of the Economy and Finance explains that claims are made to the seller and that this guarantee is separate from any commercial warranty offered by a brand.
Does the CE marking prove that a robot won’t fall off the window?
No. The DGCCRF explains that the CE marking represents the manufacturer’s declaration that the product meets the applicable regulatory requirements; it is not a certification mark. It does not replace the instructions or the guidance on securing the device for the type of glass.
