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.
