"Cleaning Head" An elongate cleaning head comprises an outer housing (10) defining a suction chamber and an inner housing (20) affording a cleaning liquid distributing chamber (26) from which liquid flows through closely spaced fine outlets (33) into a liquid delivery chamber (29) at a position spaced from the mouth (25) of the inner housing. The side walls (22) of the inner housing are formed with baffles (24) including upwardly divergent wings (24a,24b) so that air flow through the suction chamber initially diverges away from the open mouth thereof towards an upper zone (17) between the upper wall (22a) of the inner housing (20) and the upper wall (13) of the outer housing (10), in which upper zone the air-flow converges to an outlet (11). |
