  • Patent number: 6101669
    Abstract: A vacuum appliance is disclosed, comprising a collection canister and a powerhead housing a motor and impeller assembly for establishing vacuum pressure within said canister. In one embodiment, the appliance is of the wet/dry variety. A filter assembly comprising a rigid filter cage around which a filter is disposed. The filter cage is supported on an underside of the powerhead and extends into the collection canister such that the bottom of the filter assembly is at or substantially near the bottom of the collection canister. As a result, deflection of the collection canister as a result of vacuum pressure built up in the canister is resisted by the rigidity of the filter cage. In one embodiment, a frame within the powerhead serves the dual functions of supporting the motor and defining one wall or surface of an impeller chamber in which an impeller rotates to create the vacuum pressure.
