Abstract
A robotic pool cleaner includes a housing with an interior chamber. A filter within the interior chamber filters water drawn through a water inlet provided in a bottom portion of the housing. Filtered water is discharged through a discharge port provided in a upper portion of the housing. Rotatably-mounted supports attached to the housing support and guide the cleaner on the pool surface. An electric motor mounted in the chamber is configured to move the cleaner on a pool surface. A pool cleaner controller electrically connected to the electric motor controls movement of the cleaner and receives communication signals transmitted by a remote power supply over a two-wire electric cable having first and second conductors. The pool cleaner controller is configured to provide uninterrupted electric power to the electric motor while the pool cleaner controller also receives pulsed communication signal from the remote power supply over the two-wire cable.
