ABSTRACT:
A cleaning head for installation in the bottom surface of a swimming pool includes a rotary pop-up jet producing element having a hollow cylindrical lower section open at its bottom and an enlarged cylindrical hollow upper section closed at its top. An outlet opening is disposed in a vertical cylindrical wall of the upper section. A camming pin extending from the vertical cylindrical wall of the lower section engages opposed, staggered upper and lower sawtooth-like camming surfaces disposed along an inner cylindrical wall of a stationary section of the cleaning head. The stationary section of the cleaning head sealably engages with a housing installed in the bottom surface of the swimming pool and is sealably coupled to an intermittent high pressure water supply. As the water pressure is intermittently pressurized, the pop-up jet producing element pops up and down, the camming pin engages upper and lower edges of the saw-tooth-like camming elements, causing the rotary pop-up element to rotate intermittently each time the water pressure is turned on and off. Each time the water pressure is turned on, a jet of water is ejected from the outlet opening, which is exposed above the edge of the housing as the pop-up jet producing element pops up. Each time the water pressure is turned off, the jet producing element is retracted into the housing so that the top of the upper section is flush with the bottom of the pool.
