ABSTRACT:
An underwater vacuum cleaner for cleaning debris from the bottom of a pool has a collection chamber formed with an inlet, an exhaust port and an actuator port. Operatively associated with the actuator port is a reciprocable push button which moves between a seated position wherein the actuator port is closed, and an unseated position wherein the actuator port is opened. With the push button in the seated position, an air lock is created in the collection chamber when the chamber is submerged into the pool. Once the collection chamber is submerged, movement of the push button into its unseated position breaks the air lock and allows water, and debris carried by the water, to enter the collection chamber. The collection chamber is emptied of water for subsequent use, and the collected debris is held trapped in the chamber, by withdrawing the collection chamber from the pool. Specifically, upon withdrawal of the collection chamber from the pool, the push button is pulled into an unseated position by the water draining from the collection chamber through the filtered exhaust port.
