The knot of screenwash consists of a motor-reducer (the electric motor with a reducer), levers and brushes. The cleaner electric motor – with excitement from permanent magnets, with two speeds of rotation. For protection of the electric motor against overloads in a cleaner the thermobimetallic safety lock is established.

The cleaner works in three modes:

The I mode – faltering, is provided to the electronic R1 relays installed in the assembly block. This relay also includes a cleaner motor-reducer (small speed) at inclusion of a washer of a windshield;

The II mode – constant, with a small speed of the movement of brushes;

The III mode – constant, with a high speed of the movement of brushes.
