FAQ
Do window cleaning robots need a power outlet?
Most do, including the WINBOT W2S PRO and HOBOT 388, which are corded. The W2S PRO costs less than its OMNI sibling because it has no station, so it works best for windows near an outlet.
Are window cleaning robots safe on high windows?
Use the safety tether. Most of our picks list a safety rope or tether, and some add a backup battery (the HOBOT 388 lists a built-in UPS). Supervise the robot when it cleans upper-floor glass.
Can window robots clean walls or mirrors?
They're made for smooth glass, including glass doors and mirrors (the WINBOT W1 PRO lists both).
