ABSTRACT:
The invention provides an automatic swimming pool cleaner which is self propelled over underwater surfaces by a pivoting oscillator. The pool cleaner includes a row of bristles extending from the housing from scrubbing the surfaces to be cleaned. Surrounding the row of bristles is a skirt extending from the housing. The skirt is tapered along its length, relative to the bristles, to control the flow of water through the pool cleaner and thus provide effective movement of the cleaner.
