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.

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.
