Top complaints
Ecovacs WINBOT W2S OMNI Window Cleaning Robot
- Needs watching, saves little time
Trusted Reviews says it didn't save any time because the tester felt they had to watch it in case it got stuck or fell off. Amazon's summary for this pooled listing says it can get stuck.
- Won't fit small or hard-to-reach windows
Trusted Reviews couldn't use it on small top-opening windows (minimum pane is 30 x 40 cm) and found no safe way to place it on most first-floor exterior windows.
Source: Trusted Reviews - Noisy; spray blows away in wind
Trusted Reviews recorded 68 dB, found the cleaning solution didn't reach the glass in a slight breeze, and noted a short 1.2 m power cable.

Ecovacs WINBOT W2 Omni Window Cleaning Robot
- Lost suction on gapped panes
Reviewed found it lost suction, stopped and threw an error about ten feet up on floor-to-ceiling panes with gaps (it did not fall). How-To Geek says surfaces must be mostly square, without cracks or protruding sections, or suction can break.
Source: Reviewed, How-To Geek review - Debris left in corners and edges
How-To Geek found some debris left in corners and along edges that needed a quick wipe by hand. Reviewed, by contrast, saw full coverage to the frame.
Source: How-To Geek review, Reviewed - Pricey and niche; moving it is tedious
How-To Geek calls it pricey for potentially limited uses with a less compelling app. Reviewed calls it too niche for an overall recommendation and says reattaching it pane by pane is simple but tedious.
