A window wiper which is particularly suitable for commercial heavy duty situations such as bridge windows of ships. A wiper blade (1) is carried by two motors (3, 4) one at each end and in a preferential arrangement each motor (3, 4) has a self-parking feature, and the self-parking feature of each is actuated at each cycle or stroke of movement across the window (2) so as to keep the two motors (3, 4) in step. |
