ABSTRACT:
An improved water jet pool cleaner system includes a pool cleaner with a buoyant housing powered about the pool by forward and reverse driving nozzles so dirt and other debris is gathered at the low point on the bottom of the pool by the action of depending cleaner hoses. Water from the filter pump enters a fluid reservoir from which it flows along parallel flow paths to the forward and reverse driving nozzles, to a turbine, and to the cleaner hoses. Pressurized water is directed to the forward and reverse nozzles through a rotary valve which is rotated by the drive train connected to the turbine. The parallel flow paths permits water to be provided to the driving nozzles, to the turbine and to the cleaner hoses at pressures substantially equal to the fluid reservoir pressure. The system uses a flow diverter downstream of the main pool filter to divert the proper amount of water to the cleaner. Manual and automatic flow diverters and a novel in-line filter are also disclosed.
