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.

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.
