A pool cleaner for connection to a suction source, said pool cleaner comprising: a cleaner housing supported by a plurality of wheels for rolling movement over submerged surfaces in a swimming pool;
means defining a turbine chamber within said housing, a debris inlet nozzle for vacuum-drawn flow of water and debris generally circumferentially into the turbine chamber, and a suction outlet fitting for connecting the turbine chamber to the suction source;
a turbine rotatably supported within the turbine chamber and adapted to be rotatably driven by vacuum-drawn flow of water from said inlet nozzle and
through the turbine chamber for flow through said outlet fitting to the suction source, said turbine chamber including a plenum zone exposed to substantially one axial face of said turbine, said plenum zone being interposed between said turbine and said suction outlet fitting; and
drive train means coupled between said turbine and at least one of said wheels for rotatably transporting said cleaner housing in a normal forward direction. |
