CLEANING HEAD AND METHOD ABSTRACT OF THE DISCLOSURE A cleaning head for use in a water extraction cleaning process comprises a suction chamber for connection to a source of suction and having an open mouth. An inner compartment is arranged substantially centrally within the suction chamber and has side walls defining an open mouth in the plane of the open mouth of the suction chamber. Associated with the inner compartment there is a cleaning liquid delivery duct formed with a plurality of closely spaced fine outlets adapted to allow cleaning liquid to flow substantially dropwise into the inner compartment at a position spaced from the mouth thereof. When the cleaning head is applied to a surface to be cleaned, cleaning liquid is applied to a part of the surface which is shielded from air flow but arising from vacuous conditions within the suction chamber, but, upon movement of the cleaning head in either of at least two opposed directions, the area then wetted by the cleaning liquid is immediately subjected to suction drying.
