Abstract
A cleaning apparatus is provided for a preferably planar surface, in particular a window pane, and has a wiping device and a plunger which keeps the wiping device in contact with the surface and also, by way of an open side, bears against the surface and seals it around the edge. A suction device generates a negative pressure in the plunger. The plunger is provided with driving rollers, which are actuated by motor, for moving the plunger together with the wiping device. The suction device has at least two fans which are each provided with their own outlet opening.
