ABSTRACT:
A windshield wiper is disclosed having a rotatable roller scrubber mounted on a roller retainer which is attached to the windshield wiper frame or blade. The roller retainer may have a semi-cylindrical configuration defining an internal space in which the roller scrubber is mounted. The roller scrubber has a plurality of elongated scrubbing strips and is located in the roller retainer such that one of the scrubbing strips extends outwardly of the assembly to bear against a window or windshield of the vehicle. A pair of roller retainers, each having a roller scrubber, may be attached to a single windshield wiper frame. Stops are located within the interior spaces of the roller retainers so as to enable each of the roller scrubbers to rotate in only one direction. The stops are located such that the roller scrubbers attached to a single windshield wiper frame rotate in opposite directions. Cleaning brushes extend into the internal spaces so as to clean the scrubbing strips as the roller scrubbers rotate.
