ABSTRACT:
The present invention provides an improved brush for cleaning underwater surfaces, such as swimming pool walls and bottoms, and uses a hinged wing that presents an inclined plane to the water when the brush is moved in its downward stroke. The wing thus acts to exert a desired force upon the brush which urges the brush against the surface being cleaned. On the return stroke of the brush, the hinged wing is caused to move to a position trailing the brush, where it avoids urging the brush back into contact with the surface that was just cleaned on the downward stroke. Rather, this trailing position helps to keep the brush off of the cleaned surface, and creates little or no drag for the return stroke.
