Abstract
An improved 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 a hydraulically contoured external housing having a stabilizer float integrated with a carrying handle at an elevated rearward location. The pool cleaner additionally incorporates modular components including a simplified mast unit and related water distribution manifold for delivery of water under pressure to a water turbine drive unit for rotatably driving cleaner wheels to travel over submerged pool surfaces, with a portion of the pressurized water inducing a vacuum action for collecting debris within a porous filter bag. The modular components are mounted on an internal frame which is quickly and easily accessible for service or maintenance by removal of the external housing.
