ABSTRACT:
A pool cleaning vacuum employing multiple power supply sources and associated method includes a body including first, second and third vertically juxtaposed chambers formed therein. The chambers share a wall with the second chamber wherein the third chamber is isolated therefrom. A motor assembly and a filter section are housed within the first chamber. The filter section is located downstream of the motor assembly, and has an open lateral face exposed to the aqueous environment. An anchor shaft is seated within the second chamber and extends through an entire longitudinal length of the body. A vacuum head is pivotally attached to the anchor shaft. The vacuum head includes a conduit in communication with the filter section, and a plurality of wheels rotatably coupled to opposed corners thereof. A mechanism transmits a predetermined quantity of power to the motor assembly.
