A filter for a vacuum cleaner includes a top having an open center, a bottom plate having an aperture, a center, an inside surface facing towards the top, an outside surface facing away from the top, and a catch configured to pass-through the aperture, filter material being secured between the top and bottom plate. An adaptor for a filter cage or the filter cage itself includes an elevated ring that engages the catch of the filter.
A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly includes a vacuum module and a collector module configured to collect debris and operatively coupled to the vacuum module. The collector module includes a canister assembly with an intake port, an output port, and a flapper valve coupled to the intake port. An elbow assembly couples the vacuum module to the collector module and includes an intake end attached to the output port of the canister assembly. The intake end has a foam section disposed on a grill insert. Upon removal of the canister assembly from the collector module, the flapper valve moves to a closed position over the intake port of the canister assembly to keep debris contained in the canister assembly, and the grill insert and the foam section remain in place in the intake end of the elbow assembly.

A corner support assembly for supporting a stack of containers includes a bar defining a corner and having a first end, a second end, an interior surface. A bracket is operatively coupled to the bar. The bracket includes a front end spaced away from the bar and a back end facing the interior surface of the bar. The bracket is disposed between the first end and the second end of the bar and oriented substantially perpendicular to the bar.
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.
A vacuum cleaner comprising a receptacle having a working air inlet and an associated filter, the filter in communication with and downstream from the working air inlet, is disclosed. The vacuum cleaner further includes a housing containing a motor and having a cooling air outlet from the motor and a working air outlet, the working air outlet in communication with the working air inlet of the receptacle through a working air impeller, wherein the cooling air is directed to the receptacle, and the cooling air passes through the filter before exiting the working air outlet of the housing.

APERTURE ASSEMBLY FOR USE WITH A PHOTOSENSOR SYSTEM AND A SECURING MECHANISM FOR THE APERTURE ASSEMBLY
A cost-effective photosensor system for rotor position detection includes securing an aperture assembly to an off-the-shelf infrared radiation-emitting component and/or an off-the shelf infrared radiation-detecting component. The application discloses an aperture assembly that may be stamped from a thin, opaque, elongated piece of plastic having an aperture window through which a radiation beam may pass and be focused. The aperture assembly also has a locking system for securing the assembly to the off-the-shelf photosensor system component, and an alignment system to direct the infrared radiation beam. A replaceable stamped aperture assembly for use in a rotor-sensing system and a method of providing a replaceable aperture assembly and securing it to an infrared component of a photosensor system are also disclosed.
The disclosed cleaning device has a suction unit that can be used to take in liquid, a tank that can be used to hold the liquid, a mouth that can be used to pour liquid from the tank, and wheels that form a base. It also has a pivot that can be used to rotate the tank between a normal use position and a pouring position. The pivot is arranged so that in the pouring position, the center of gravity of the unit remains within the horizontal range of the base, even as the mouth of the tank falls outside the horizontal range of the base. As shown, the pivot is 12 inches above the floor and within the horizontal range of the base. In this position, it remains laterally between the center of gravity of the tank and the edge of the base when the tank is emptied.

A vacuum cleaner filter bag retainer includes slots on each side which receive a cardboard plate attached to a filter bag. The plate is slid into the slots of the filter bag retainer such that openings in the plate and bag match with an opening in the filter bag retainer. The retainer is attached to a tank through an opening in the tank, and an inlet fitting extends from outside the tank, through the retainer, and into the bag. The inlet fitting, therefore, prevents the bag from sliding out of the slots in the retainer. A swivel fitting loosely traps the inlet fitting adjacent the filter bag retainer through threads on the swivel fitting and the retainer. The inlet fitting also holds a hose to the inlet fitting.
