Abstract
A pool cleaner floats on the surface of a pool. The cleaner includes a pump and filter, the filter being connected downstream of the pump. A vacuum head, connected by a hose to the pump, is moved around the pool, to direct water from the pool through the pump and filter. Due to the absence of any filter on the upstream side of the pump, the cleaner maintains its efficiency for a longer time than comparable cleaners of the prior art. The cleaner may also include a rotary strainer, placed upstream of the pump, for removing large pieces of debris. The strainer includes a slidable, transparent access cover which allows visual monitoring of the condition of the strainer, and permits easy access to the interior of the strainer, for removal of debris. In another embodiment, the cleaner includes a filter unit having a continuous sheet of filter material which advances automatically when the filter material previously exposed to the water has become clogged. The cleaner therefore substantially speeds the process of cleaning a pool.
