A vacuum cleaner bag assembly is adapted to be removably disposed within a tank of a vacuum cleaner, and the bag assembly includes a panel assembly made from a first material and forming an enclosure having an interior volume, and an aperture extends through the panel assembly. A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank.

Vacuum bag

A vacuum cleaner bag assembly is adapted to be removably disposed within a tank of a vacuum cleaner, and the bag assembly includes a panel assembly made from a first material and forming an enclosure having an interior volume, and an aperture extends through the panel assembly. A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The first material may have a wicking barrier that inhibits wicking when the bag assembly becomes wet. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank and, together with the wicking barrier and a properly chosen first material, enhances performance of the vacuum bag assembly when wet.

Wet/dry vacuum bag

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.

In a device that uses the tank from a conventional vacuum cleaner, the tank is under positive pressure. A cap fits over a tubular element inside the tank and closes the conventional air inlet. The cap has a peripheral wall that extends between a solid back and a front radial rim, and interior axial ribs. The lid is held by a latch that has an element that pivots with respect to the tank and the lid, and a clasp that has a bent arm. A tensioner pulls the bent arm. The tensioner has a threaded rod that extends from a handgrip though a hole in the pivoting element. A nut on the clasp receives a threaded end of the threaded rod, enabling the handgrip to be used to tighten the clasp. An outer wall of the latch is disposed outwardly of the threaded rod and the bent arm.

Vacuum cleaner

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.

Vacuum cleaner with hose fence and tool storage

Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.

Removable internal air diffuser

A filter shaker for a filter assembly disposed in a vacuum includes a housing that removably mounts to the filter and/or a support for the filter and a vibrator assembly carried by the housing. When actuated, the vibrator assembly vibrates the filter to clean particulate matter from the filter. The vibrator assembly includes a motor that drives an eccentric and an actuator that periodically impacts against a portion of the housing to cause the vibrations. The housing includes a mounting assembly for mounting the filter shaker to the cage and/or filter in an operative position and a locking assembly for locking and unlocking the filter shaker in the operative position to prevent the filter shaker from vibrating off. In the operative position, the filter shaker covers an open end of a tubular filter and thereby forces air to be directed through filter material of the tubular filter.
