  • Patent number: 5720055
    Abstract: A cleaning device which can be used as a personal hygienic unit, as a unit for cleaning a diaper area of an infant, and rinsing soiled diapers, or as a cleaning unit for clearing clogs in a toilet or drain pipe. There is included a flexible hose which is connected to a water supply and to an inlet of a flow control valve. An outlet of the flow control valve is connected to a rigid hollow handle for delivery of water through the handle to a sprayhead secured at an acute angle in relation to a longitudinal axis of the handle so as to deliver water upwardly from the spray head openings when the device is in use. A secondary unit is independently connected to a water supply for delivery of water to a hand-held spray nozzle to allow cleaning of a diaper area of an infant and rinsing soiled diapers. As an alternative to the sprayhead, there is provided a flexible, bendable pipe having a free open end, through which a stream of water can be delivered to an immediate proximity of a clogged toilet or drain.
