ABSTRACT:
A vacuum cleaner system having an intake nozzle integrally formed with a concave lower portion of a main vacuum canister of a vacuum cleaner system. The intake nozzle protrudes downwardly and communicates with an opening in a convex upper surface of a liquid pan removably attached to the concave lower portion of the main vacuum canister. Attaching the intake nozzle with the concave lower portion of the main vacuum canister allows the interior area of the liquid pan to be more easily cleaned. In an alternative preferred embodiment, an intake member is included which is secured to the concave lower portion of the main vacuum canister. The intake member includes a downwardly protruding tubular member which protrudes outwardly of the lower surface of the main vacuum canister. The tubular member has a first opening which forms an intake port on the side surface of the main vacuum canister and a second opening forming an exhaust port at a lowermost end portion thereof. The intake member further includes a downwardly depending shroud for enabling the main vacuum canister to be more securely supported on a floor. In one preferred embodiment the liquid pan includes a pivotally foldable handle portion for facilitating handling of the liquid pan and a pivotally, removably disposed comb for filtering debris such as hair and pieces of cloth from a liquid filtering agent when the filtering agent is emptied from the pan. In another alternative preferred embodiment the liquid pan comprises a six-sided shape and includes a pair of pivotally coupled handles foldable upwardly into abutting contact to form a single handle by which the liquid pan assembly may be more easily manually handled and articulated.
