1. A power supply for powering pool or spa equipment, comprising:
- a power supply unit external to a pool or a spa;
a first inductive power coupling including an inductor circuit, said first inductive power coupling in electrical communication with the power supply unit and at least partially embedded in a wall of the pool or spa;
a second inductive power coupling including an inductor circuit, said second inductive power coupling received by said first inductive power coupling in the pool or spa, wherein the inductor circuit of the first power coupling inductively transmits power from the power supply to the inductor circuit of the second inductive power coupling for powering a cleaner in a pool or spa connected to the second inductive power coupling;
a cable interconnecting said second inductive power coupling with the, cleaner, the cable delivering electrical power to the cleaner and permitting movement of the cleaner relative to said first inductive power coupling while said second inductive power coupling is received by said first inductive power coupling; and
wherein the cleaner includes;
a rechargeable battery that is rechargeable by the power supply; and
a controller including control logic for determining when the rechargeable battery is low on battery power and, in response to detected low battery power, automatically navigating the cleaner to the first inductive power coupling so as to receive power from the first inductive power coupling to charge the rechargeable battery.

Abstract
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.
