Abstract
A cleaning system comprising a cleaner body configured to travel through a water pool powered by a positive pressure water flow supplied via a flexible hose. The system is characterized by:(1) a water distribution subsystem carried by the cleaner body including a state valve selectively operable in a forward or redirect state and a mode valve selectively operable in a top or bottom mode; and/or(2) a wall fitting including an outlet section extending downward at an oblique angle between 15° and 75° to reduce the likelihood of hose restraint.
