Abstract

The paintbrush-cleaning device includes a housing with an open top, a bottom drain and a central space, containing paintbrush-cleaning liquid therein. A pair of rotatable radial brushes brackets the paintbrushes in the central space and are powered by an electric motor connected to the housing. A number of spaced upwardly directed jet nozzles are disposed in the central space and direct streams of cleaning liquid under pressure upwards towards the paintbrushes. An impeller pump may be connected to a manifold in the central space, from which manifold the jet nozzles extend. Two radial brushes may be used, with the members disposed opposite each other adjacent the sides of the top opening. The radial brushes bear a bristle portion comprising cleaning bristles, which is configured in a spiral along the length of the radial wound brush. The spiral pattern and placement of the radial brushes in the central space effectively clean paintbrushes while transporting cleaning fluid upward and forward from the central space to the paintbrushes via the Archimedes screw principle. The device is simple, durable and efficient.
