Abstract
In a vessel such as a swimming pool, a turbine device is positioned on the bottom of the vessel to create an upward flow of water. The upward flow carries with it any larger debris, which are thereafter carried along the edge of the vessel and recovered by a skimmer. The turbine device is powered by the suction stream of a fluid circulation pump and filter system. Suction is thus created along the bottom of the vessel, which removes small debris. The upward flow of the turbine device is created by a plurality of spaced outlets which surrounds an impeller inlet. The outlets form high velocity streams which are spaced in a manner to exclude large debris from entering the impeller inlet.
