ABSTRACT:
A swimming pool cleaner discharges water jets under the cleaner body, directed toward its center from its sides, to agitate and lift debris toward one or more vacuum intake openings, to greatly enhance the cleaning ability of the cleaner. The suspended dirt and debris become semi-buoyant under the force of the jetted water which is preferably moving in the same direction as the cleaner, so that the relative speed between the cleaner and the suspended dirt and debris is reduced, thereby enabling the cleaner to move at a relatively faster rate and still clean with equivalent or even greater efficiency than a pool cleaner that is not equipped with directional cleaning water jets. In addition, displaced front and back orientations of the intake ports allow for longer time for any dirt and debris to be picked up.
