  • Patent number: 4640784
    Abstract: A method and apparatus of cleaning debris from swimming pools includes upper spray jets mounted to one of the pool endwalls for moving a surface layer of pool water approximately 150 millimeters in depth toward the opposite endwall, lower spray jets mounted to each pool sidewall near the bottom for carrying submerged debris to the moving surface layer of pool water, and at least one weir mounted in the opposite endwall which connects to a filter. The weir is adapted to create a positive suction force in the surrounding pool water when the system is operating to draw the pool water and debris it contains from the pool, into the weir and then to the filter for removal of the debris from the water.
