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.
