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 W1 Pro Window Cleaning Robot
- Tied to an outlet
Techlicious says it must stay plugged in, and the 15.4-foot cord sometimes needed an extension cord; the review title calls it 'held back by its cord'.
Source: Techlicious review - Limited window fit
Techlicious says it won't work on mullioned windows, decals or curved glass, and lever handles stopped it reaching under them. CHOICE lists minimum glass thickness and frame-height requirements and says you need windows that suit it.
Source: Techlicious review, CHOICE review - Loud, with ongoing fluid costs
CHOICE measured about 73 dBA, around a stick vacuum, and found the fluid ran out after about 30 minutes against a one-hour rating. Techlicious measured about 68 dB. A Techlicious reader reported streaks on every window within a month.
