1. A pool cleaner for travel along submerged surfaces of a swimming pool to collect and dislodge debris, comprising:

  • an internal frame;

    a hydraulically contoured cleaner housing including upper and lower housing shells mounted on said frame;

    a plurality of wheels rotatably mounted on said frame and positioned outside said housing for supporting the cleaner on a pool surface;

    a mast unit mounted on said frame and including a supply mast having an upper end positioned outside said housing for connection to a supply of water under pressure, and a suction mast having an open lower end exposed through said lower housing shell to an underside of said housing and an upper end positioned outside said housing for removable mounting of a debris collection bag;

    a water distribution manifold carried by said frame and coupled to said supply mast for receiving and distributing water under pressure from said supply mast, said water distribution manifold including at least one upwardly directed jet nozzle for inducing an upward hydraulic vacuum flow through said suction mast for drawing water and entrained debris upwardly through said suction mast; and

    a water powered drive system carried by said frame and including a water driven turbine for rotatably driving at least one of said wheels, said water distribution manifold further including at least one drive jet for supplying a portion of the water under pressure for rotatably driving said turbine;

    said housing substantially enclosing and encasing said frame and said water distribution manifold and said water powered drive system carried thereby, said upper and lower housing shells being separately removable from said frame for access to said frame and said water distribution manifold and said water powered drive system;
