A birdbath assembly is disclosed for controlled, automatic filling, self-cleaning and emptying with water pressure. The assembly includes a spray nozzle mounted for sliding movement through the inside surface of a bowl in response to water pressure. A series of solenoid operated fluid valves are sequentially opened by a preset electrical timing control to provide low water flow to fill the bowl, a subsequent greater water flow to raise the nozzle, agitate the water and any effluents in the bowl, and remove/expel the water and effluents from the bowl, followed by further low water flow to refill the bowl for reuse. A kit for converting conventional birdbaths to the present self-cleaning and filling invention is also disclosed.
