A vacuum container mounted on an inclined slope and having a liquid water storage container mounted beneath the incline of the vacuum container. The water storage container may support the vacuum container. The slope may be of sufficient angle to allow debris to be emptied from the vacuum container by gravity when the access door is opened. A filter housing may be mounted to and supported by the vacuum container. By flush mounting the clean out end of the filter housing with the clean out end of the vacuum container, a single access clean out door may be used to access both simultaneously. This compact design provides efficient interaction and plumbing between the water tank, vacuum tank and filter housing as well as concentrating weight and reducing floor space.

A light weight floor sweeper having a very low profile sweeper head that uses a sweeping brush and cleaning pad to slide across the surface to be cleaned. The floor sweeper head is mounted to an elongated handle by means of a universal pivot or universal joint which allows the floor sweeper head to easily pivot about the handle in any direction to pick up debris under over hanging cabinets or under furniture. A sweeping brush is mounted on the bottom of the sweeper head to provide sweeping action as the floor sweeper is moved in any direction. Furthermore there is a soft cleaning pad releasably mounted adjacent to the brush to entrap dust and particles that the brush does not pick up. The brush is powered by a small electric motor. A removable dust-receiving tray is mounted in the sweeper head to receive debris swept by the brush.

An automatic cart wash apparatus. The automatic cart wash apparatus provides improved cleaning of stock carts on a regular basis over manual cleaning by store employees. The automatic cart wash apparatus includes three main stages: a debris removal (vacuum) stage, a cleaning (wash, sanitize, rinse) stage, and a drying stage. The debris removal stage uses forced air and / or suction to remove solid and generally non-soluble waste, such as a paper or other trash and debris, from a stock cart. The cleaning stage uses a selection of detergents, sanitizing agents, and rinse agents to remove soluble or sticky waste, such as food and liquids, and to kill germs, viruses, and bacteria present on the cart. The drying stage removes excess liquids from the cart making it ready for use by the next customer.

The present invention relates to a central vacuum power unit comprising in combination a canister, a chamber for collecting debris, a first plate, a second plate, a third plate, a duct, a motor-fan assembly, a filter, and a first baffle. The duct extends between the first and second plates and is in fluid flow communication with respective openings defined in the first and second plates. The sidewall of the canister, the first and the second plates and the duct defines an acoustic damping chamber covered with a lining of sound absorbing material.

An upright surface treating appliance includes a main body having a user operable handle, a surface treating head connected to a yoke moveable relative to the main body, a stand moveable relative to both the main body and the yoke between a supporting position for supporting the main body in an upright position, and a retracted position, and a stand retaining mechanism for releasably retaining the stand in the supporting position and from which the stand is releasable upon application of a force to one of the main body and the stand. The yoke is moveable relative to the main body in response to an impact on the surface treating head to apply said force to the stand. This allows the force of the impact on the surface treating head to be transferred through the stand to the stand retaining mechanism, which, depending on the magnitude of the impact, can release both the stand and the yoke for movement relative to the main body. This avoids the need to provide separate releasing mechanisms for both the yoke and the stand.
