ABSTRACT:
A self-cleaning screen that automatically cleans both the inside and outside surfaces of the cylindrical screen using only the rotation of the cylindrical screen itself. This self-cleaning ability is accomplished by using a fixed brush on the exterior surface of the screen, and a freely rotating brush on the interior surface of the screen, where the freely rotating brush is driven by the movement of the screen itself.
