An arrangement for wiping a vehicle window has a wiping element adapted to rotate through a predetermined wiping angle, an electric motor having a rotatable output shaft which is connected with the wiping element so as to rotate the same, and a switching device operative for reversing the direction of rotation of the electric motor when the wiping element reaches the ends of the wiping angle. The wiping element may be mounted on the output shaft of the motor or on an output shaft of a reduction transmission between the electric motor and the wiping element. The switching device may include a direction-reversing switch whose contacts are introduced in the electric circuit of the electric motor, and two switch-actuating pins mounted on an output gear which is fitted on the output shaft. One of the switch-actuating pins may be displaceable relative to the other so that the wiping angle through which the wiping element rotates, can be adjusted.
