A wiper device for vehicle windows, comprising a motor;
- at least one wiper which is moved back and forth over a window and having a wiper blade movable into a parking location and an elastically deformable wiper lip formed on said wiper blade;
- a control unit controlling said motor, said wiper lip being storable in different parking positions in said parking location;
- and a timer arranged so that the parking positions of said wiper lip in said parking location are alternatingly triggerable at time intervals when the wiper device has not been operated for a predetermined time span.
A process for wiping vehicle windows with a wiper device having a motor, comprising the steps of moving at least one wiper back and fourth over a window, with a wiper blade movable into a parking location and a elastically deformable wiper lip formed on the wiper blade;
- controlling the motor by a control unit so as to store said wiper lip alternatingly in a first or a second parking position in the parking location, which positions correspond to a first and a second drag position;
- changing by the control unit the parking position of the wiper lip at time intervals when the wiper device has not been operated for a predetermined time span.
