Abstract
A method and apparatus for enabling a pool cleaner to travel through a water pool to collect dirt and other debris from the water and/or pool containment wall. The cleaner defines a suction passageway having an inlet open to pool water and an outlet adapted to be coupled via a flexible hose to the suction side of an electrically driven pump. A resulting suction flow, from the inlet to the pump, functions to (1) carry dirt and other debris to a filter and (2) to drive a turbine for propelling the cleaner. In accordance with the invention, the suction passageway inlet includes an orifice defining a physical flow area Aand configured to create an 'effective' flow area Asmaller than A, downstream from the orifice. The small effective flow area Acreates a water flow of sufficient velocity to efficiently drive the turbine whereas the larger physical flow area Apermits debris to pass more readily.
