Abstract: A mobile machine for removing dry particulate matter from a mop, cloth or duster by agitation. A drum with flexible, resilient fingers rotates and agitates the mop, cloth or duster to loosen the particulate matter. An electric fan sucks ambient air and the particulate matter to a chamber wherein it is wetted by a liquid mist introduced by spray nozzles. The mist combines with the particulate matter to form larger particulates. The particulate matter and larger particulates are passed through a filter to remove the particulate matter and larger particulates, which drop onto a removable tray.

Abstract: An improved, electric motor driven dust mop vacuum cleaner is provided that employs rotating brushes, high vacuum, and an efficient air filtration system. The rotating brushes housed in a closely fitting tub remove the dust and dirt from the dust mops and by means of impellers in the vacuum motor chamber. The dust and dirt are then passed on to the air filtration system. The air filtration system consisting of an intake port, removable particulate trapping tray, and exhaust port filters, remove the particulates from the air before returning it to the environment. The particulate trapping tray located at the base of the unit and behind a hinged door, contains an effective particulate trapping liquid. The entire apparatus is movable by means of casters mounted on the base of the unit.
