Abstract
This invention relates to an automatic pool cleaner, particularly suitable for domestic swimming pools which operate on the interruption of an induced flow of water through the cleaner and wherein the control of the interruption is effected through a tubular axially resilient diaphragm one end of which is closed and adapted to hold normally closed a passage from the head of the pool cleaner to the usual form of flexible hose connecting the pool cleaner to the filtration unit.
