ABSTRACT:
A submersible swimming pool cleaner including a wheeled housing into which an intake fitting for the intake of pressurized water is disposed, and an angularly disposed manifold member inside of the housing containing a plurality of apertures through which the pressurized water is directed at an angle against the pool bottom. A pair of wheel members are positioned at a front of the housing to facilitate transport of the apparatus across the pool bottom and to provide a clearance between the leading edge of the housing and the pool bottom through which debris may enter into a cavity of the housing. The housing further includes a wiper blade secured to the housing rearwardly of the manifold and positioned to seal and direct water along the pool bottom when the apparatus is in operation and thereby further loosen debris from the pool bottom. A debris collection bag is fixed over an exhaust aperture in the rear of the housing for collecting debris.
