<p>A pool cleaner, including a valve chamber (4) having an inlet and two outlet orifices and a valve (7) within the valve chamber. The valve continuously oscillates between first and second positions due to water flow through the chamber from the inlet to the outlet orifices. A bias means (8), in the form of resilient projections on the valve (17), the valve being offset in the chamber or a stiff projection from the valve (13) contacting the wall of the valve chamber. The bias means applies an eccentric influence on the valve such that the operator does not need to initiate oscillation of the valve.</p> |
