Abstract: A pre-filter for a filter system includes a frame having air flow openings having a height and an top portion having a width and a depth. The pre-filter includes a filter panel having a width less than or equal to the width of the top portion and a depth less than or equal to the depth of the top portion at least during insertion of the filter panel into the frame, and height equal to or greater than the height of the air flow openings. A filter system using the pre-filter includes a tank, an air intake aperture, an air exhaust aperture, and a cartridge filter. Another filter system has a relatively large air intake aperture that permits easy debris dumping. A vacuum cleaning system using the filter system includes a support structure connected to the filter system by a release lever.

Abstract: A fan having a housing including a front piece that is separable but connectable to a back piece is disclosed. The front piece has a first connecting edge and a downstream edge, and the back piece has a second connecting edge and an upstream edge. The second connecting edge is configured to be connected to the first connecting edge. The fan may include a handle, the handle having a first portion integral with the front piece and a second portion integral with the back piece, the first portion configured to be connected to the second portion. The fan may further include air guide ribs provided on an interior surface of the housing and/or a ramp that starts at a location downstream of the upstream edge of the housing and ends at the downstream edge of the housing.

Abstract: A filter for a vacuum cleaner includes a top having an open center, a bottom plate having an outermost edge, a center, an inside surface facing towards the top, an outside surface facing away from the top, and a catch extending from the inside surface annularly around the center, filter material being secured between the top and bottom plate. An adaptor for a filter cage or the filter cage itself includes a radial retention ring that engages the catch of the filter.

An adaptor for a filter cage or the filter cage itself includes an elevated ring that engages the catch of the filter.

Abstract: A vacuum cleaner handle mount assembly securable to a vacuum cleaner having a handle that can be pivoted from a storage position to an in-use position is disclosed. The vacuum cleaner handle mount assembly has a housing with a first and second channel, a handle with a first and second leg for respectively connecting to the first and second channel of the housing, a first and second locking mechanism for preventing the handle from pivoting during use, and a first and second nest respectively disposed in a side of the first and second channel for holding the first and second locking mechanisms respectively. The first and second locking mechanisms are rotatable from an in-use position extending across the respective first and second channels above the respective first and second legs and a storage position wherein the first and second locking mechanisms are located within the first and second nest respectively.

Abstract: A switch assembly for a wet/dry vacuum cleaner is disclosed. The switch assembly includes a switch movable by a user between an ON position and an OFF position. An automatic shutoff assembly is operable in conjunction with the switch assembly to turn the switch to the OFF position in the event that a level of liquid within a tank of the wet/dry vacuum cleaner rises above a predetermined level. When triggered, the automatic shutoff assembly exerts a biasing force urging the switch toward the OFF position. A user can manually override the automatic shutoff assembly by providing a force sufficient to overcome the biasing force.

Abstract: A new vacuum cleaner has a removable rack that combines both tool storage elements and hose fence elements in a compact arrangement. The rack is snapped in place. Laterally-spaced fence elements help hold the hose against the main body of the vacuum cleaner, and hooked upper ends help to retain the hose in place. The outer surfaces of the fence element have adjacent concave outer surfaces that form parts of two separate tool storage elements. One of the retainers has opposed ends that form a clip that can hold a vacuum hose accessory in place. The other retainer has a lower lateral end that extends radially outwardly to an upwardly projecting stem section. The stem section is sized to fit within an interior portion of a vacuum hose accessory.

Abstract: A vacuum cleaner includes a cord retainer that has a friction fit connection with an accessory receiver. The cord retainer is arranged to be selectively and detachably coupled to the accessory receiver. The vacuum cleaner may include a plurality of accessory receivers at different locations, and the cord retainer may be arranged to be selectively and detachably coupled to any one of two or more of the accessory receivers.
