Abstract
A pool cleaner includes a housing and a pump means for drawing water and debris through an intake port into a filter. A jet-valve housing having a jet-valve flap is mounted in a valve-chamber disposed over the pump means to direct a propulsion jet stream from the pump to one of a pair of opposing propulsion outlets formed in the jet-valve housing to move the cleaner in a forward direction. The valve-chamber has a wedge-shaped apex with a pair of opposing pins configured for pivotally mounting the jet-valve flap. A spring is disposed between the top portion of the jet-valve flap and the chamber apex to force the jet-valve flap to pivot between the opposing propulsion outlets when the pump is temporarily powered off to change the direction of cleaning. Upon restoring power to the pump, water from the pump closes the previously opened propulsion outlet and opens the previously closed propulsion outlet to propel the cleaner in a forward direction that is opposite to the previous direction.
