摘要： An automated washing system for vertical surfaces of buildings can include a frame assembly including a substantially planar base portion and a mast portion extending upwardly from the base portion. A pair of rolling wheels can be disposed on the opposing sides of the base portion adjacent the rear end thereof. A main brush can be rotatably disposed on the frame and partially enclosed by a shroud. An electric drive motor can drive the main brush. Bumper wheels can be 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 can be 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.

摘要： A building cleaning system for cleaning a side of a building can include an elongate brush structure that is rotated by an electric motor, a frame for supporting the brush structure that can be oriented to face toward the side of the building, and a plurality of air moving devices mounted to the frame for generating counterforce to force the frame toward the building. The air moving devices can including fans or blowers. The air moving devices can be being spaced apart from one another in an orientation that extends along the length of the frame. A lift arrangement can be provided for moving the frame along the side of the building.

摘要： A cleaning apparatus and method for cleaning generally upright surfaces, walls and windows of a building has a frame rotatably supporting one or more brushes adapted to engage the upright surface of a building. A davit supported on top of the building is connected to a cable pendently supporting the frame and brushes. A winch driven with a motor mounted on the frame operably connected to the cable operates to move the frame and brushes relative to the upright surface. A counterforce generator mounted on the frame establishes a force on the frame and brushes that maintains the brushes in effective continuous engagement with the upright surface during cleaning thereof.
