Abstract
An automatic pool cleaner is provided of the type for random travel over submerged floor and side wall surfaces of a swimming pool or the like to dislodge and collect debris. The pool cleaner includes an electric-powered traction drive system for rotatably driving cleaner wheels, and an electric-powered water management system including a water supply pump and related manifold unit for venturi-vacuuming and collection of settled debris within a porous filter bag. A directional control system including an on-board compass monitors turning movements of the pool cleaner during normal random travel operation, and functions to regulate the traction drive system in a manner to prevent, e.g., excess twisting of a conduit such as a power cable tethered to the pool cleaner.
