The window pane cleaning device (1) consists of a rectangular case (2) fixed to a handle bar and several wiper units which can be exchanged in order to match the size of the actual pane to be cleaned. The rubber part (4, 10, 11, 12, 13) of the wiper unit is joined to the holding elements (6, 7, 8) and held in position additionally by elevated areas (15) which fit into matching grooves (14) along its full length for maximum stability even when a module for a wide window pane is used.
