ABSTRACT:
A timer device is connected into the water supply hose of an automatic swimming pool cleaner to control the flow of water to the drive jets. The controlled flow varies over the range of full, restricted and no flow so that the speed of the cleaner may be varied. The timer device includes a bypass outlet which serves as another pool cleaning jet when the drive jets are turned off and which also serves to bodily move the timer device and to impart an axial shifting movement to the supply hose whereby the cleaner may be moved free of a trapped position before the next cycle of drive jet operation commences.
