A strong window cleaning robot with real strengths
In our independent assessment, the Hutt W66 earns 78/100 — a very good window cleaning robot.
Its strongest area is safety (96/100), followed by surfaces (92/100). In practice, electric spray.
The main caveat is quietness, where it scores 84/100. Specifically, corded.
At €300, it's priced around the category average. A dependable pick if its strengths line up with your priorities.

Will it fall off the window?
Window robots use strong suction plus a safety tether and a backup power pod, so they stay attached even during a power blip.
Does it spray its own water?
Models with an onboard tank or ultrasonic spray apply cleaning fluid as they work; simpler models use a pre-sprayed pad.
Does it work on frameless glass?
Yes — edge-detection sensors map frameless panes; framed windows are handled too. Check the surface spec above.
