An automated washing system for vertical surfaces of buildings can include a frame, a main brush rotatably disposed in the frame, at least two bumper wheels provided to opposing ends of the frame where the at least two bumper wheels can contact the vertical surfaces of building during a cleaning operation; and an electric drive motor disposed adjacent one of the opposing circular ends of the main brush.

Compact automated window washing apparatus

An automated washing system for vertical surfaces of buildings comprises a frame assembly including a substantially planar base portion and a mast portion extending upwardly from the base portion. A pair of rolling wheels are disposed on the opposing sides of the base portion adjacent the rear end thereof. A main brush is rotatably disposed on the frame and partially enclosed by a shroud. An electric drive motor drives the main brush and is powered by an onboard battery. Bumper wheels disposed on the shroud extend laterally outwardly beyond from the opposing circular ends of the main brush. The angle between the mast and the base is configured to hold the main brush against the vertical surface of the building when the mast is lifted vertically by a cable attached to the mast.
