ABSTRACT:
A system for sweeping a surface of a body of water includes a sweep, water supply lines and a controller. The sweep has a basket that is interposed between two lateral floats. There is also a float located rearwardly of the basket. The floats are coupled to the basket by way of a housing or frame. The water supply lines extend through the housing, down through the lateral floats and out to rearwardly facing nozzles. The water supply lines extend out a rear end of the housing to the controller. The controller is connected to a source of pressurized water. The controller has two valves, one valve for each water supply line. By alternately opening and closing the individual valves, the flow of pressurized water to the individual nozzles can be controlled, thereby steering the sweep as it is propelled along the surface of the pool. In another embodiment, the sweep can be automatically propelled, wherein a backup valve is provided. The backup valve alternates between providing forward propulsion and rear or back propulsion. An extension is mounted on the front end of the automatic sweep to cause the sweep to sweep along a side wall of a pool.
