ABSTRACT:
An improved storage receptacle for an automatic swimming pool cleaning device that incorporates a cleaning head secured to a retractable hose includes a barrier that is selectively operated to block the opening of the storage receptacle and prevent the cleaning head from entering the storage receptacle during use and becoming trapped. The barrier is a rod slidably disposed within a tube adjacent to the receptacle opening, and hydraulic action drives the rod upwardly to block the opening of the storage receptacle.
