Abstract: The present invention consists of an automated washing apparatus for windowpanes, comprising two tracks (7) placed on the sides of a relative windowpane (2), at least one support frame (8) mounted and sliding onto said tracks (7), at least one windscreen wiper (9) supported by the frame (8) and touching the windowpane (2), and a device (10) for moving the frame (8) along the two tracks (7), causing also the windscreen wiper (9) slide against the windowpanes (2). Said moving device (10) is equipped with a sliding element (11) mounted inside each track (7), and a device (24) for actuating the same sliding elements (11). The tracks (7) and the moving device (10) may be either installed in a pre-existing frame (3) or completely included inside said frame (3), so that only the part of the apparatus delimited by the frame (3) is visible from the outside.
