ABSTRACT:
The disclosure relates to a method and apparatus for swimming pool cleaning incorporating intermittent pop-up jet rotated nozzles; the nozzles being adapted to intermittently rotate and project cleaning jets of water adjacent said inner surface. The nozzles each have eccentrically positioned tangential water outlets forming jet outlet passages; the nozzles are vertically reciprocal and are rotatably mounted in housings having stop means such that when they are hydraulically energized by water under pressure in the housings, the nozzles emerge from the upper ends of the housings and cause jet reaction rotation thereof during upward movement which is arrested by the stop means in the housing. The housing includes a bore with clearance around the nozzle so as to provide a water bearing around the nozzle during its upward and rotative movement. A plurality of such nozzles are disposed in a swimming pool and the nozzles are successively and sequentially hydraulically energized by water under pressure from a sequencing valve which receives water from a water pump which in turn receives water from the pool.
