Our verdict

The Winbot W2 Omni pairs strong suction with a portable base station that powers it on the move, so it isn't tethered to a socket. Reliable edge detection and even water spraying make for a streak-free finish on framed and frameless glass alike.

★★★★4.2/5

A top-tier window cleaning robot we recommend without hesitation

The Winbot W2 Omni pairs strong suction with a portable base station that powers it on the move, so it isn't tethered to a socket. Reliable edge detection and even water spraying make for a streak-free finish on framed and frameless glass alike.

Its strongest area is safety (96/100), followed by surfaces (92/100). In practice, sprays its own water.

The main caveat is quietness, where it scores 72/100. Specifically, pricey for category.

At €324, it's priced around the category average. For most buyers in this category, it's one of the best choices you can make.

Frequently asked questions

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.
