Abstract: A commercial carpet brush cleaning device that removes built-up accumulations of carpet fibers and associated cleaning compound residue and dirt from a carpet cleaning brush. An elevated machine receiving area is defined having a plurality of arcuately spaced elongated openings therein and corresponding upstanding elongated cleaning tines assemblies are positioned in spaced inter-related relations to the openings. A collection and evacuation chamber below the openings removes the brush waste as it is cleaned by the rotation of the brush on the cleaning tines assembly within the device.
