Abstract
A cleaning device for cleaning the back side of a panel with a control member and a cleaning member, which is separate from the control member and which has a base member and two blades disposed thereon. The control member and the cleaning member interact magnetically through the panel, so that the cleaning member disposed on the back side of the panel can be guided along the panel while pressing the cleaning edges of both blades on the back side of the panel by means of the control member disposed in a manner corresponding to it on the front side of the panel. The two blades may be of different lengths and, by suitable geometry and arrangement of the blades or of magnetic elements, the shorter of the two blades exerts a greater pressing force on the panel with its cleaning edge than does the longer.
