Power supplies for pool and spa equipment are disclosed. In one embodiment, the power supply includes a buoyant housing, a peripheral float, at least one solar cell positioned on the buoyant housing for collecting sunlight and converting same to electrical energy, and a power cable for interconnecting the power supply and pool/spa equipment. In other embodiments, first and second inductive power couplings are provided for powering pool and spa equipment. The power couplings can also be installed using existing plumbing features of the pool or spa.

A fluid distribution system for controlling the operation of a swimming pool cleaning device includes a housing having an inlet for receiving a supply of pressurized fluid, a plurality of outlet openings and a valve chamber between the inlet and outlet openings. The housing has at least one compound cylinder having two portions with different bore diameters for slideably accommodating therein a mating stepped piston. Each portion of the compound cylinder fluidly communicates with pressurized water in the valve chamber via associated fluid pathways. The larger cylinder is vented by a relief valve actuated by a fluid driven cam that periodically opens and closes the relief valve. When the relief valve is closed, the pressure within the large cylinder pushes the piston to a first position which effects the opened/closed status of a port, e.g., allowing one of the outlets to communicate with the pressurized water in the valve chamber. When the relief valve is opened, the pressure within the larger cylinder is reduced, allowing the pressure in the smaller cylinder to push the piston to a second position which effects the opened/closed status of the port and/or opens another port to allow the pressurized fluid to be discharged through another outlet.
