ABSTRACT:
A self-contained swimming pool vacuum includes a submersible vacuum head having a housing including opposing symmetrical halves which attach together to define an elongate vacuum mouth at a bottom end, a discharge opening at the opposite upper ends and a thrust channel extending therebetween. A motor supported within the thrust channel when the symmetrical halves of the housing are joined together, drives a propeller to create a thrust through the housing from the vacuum mouth through the thrust channel and out from the discharge opening at the top of the housing. A catch bag, removably secured to the top discharge opening, collects debris sucked through the vacuum mouth. First and second primary wheels are rotatably mounted on opposite ends of the housing, adjacent the vacuum mouth, to provide a cantilever effect when maneuvering the vacuum head along a surface. The housing is further provided with drag wheels on opposing leading and trailing edges and a swivel yoke mount structured for attachment to a hollow pole to manipulate the submerged vacuum head about the surfaces of a swimming pool.
