Window i.e. windscreen, cleaning method for motor vehicle, involves superimposing rotational movement of rotary brush on oscillating translational movement that is parallel to rotational axis

摘要

The method involves arranging a windscreen wiper blade (3) at a tiltable wiper arm (2) for performing coating over a window surface and arranging a rotary brush (4) parallel to and remote from the windscreen wiper blade for performing coating over a window (1). A rotational movement of the brush is superimposed on an oscillating translational movement (6) that is parallel to a rotational axis (5), where the translational movement is produced using an auxiliary motor (7) i.e. electric motor, arranged at the wiper arm.
