Cleaning head
First Claim
1. A cleaning head for use with apparatus for cleaning hard surfaces by the application and optionally pick-up of a cleaning liquid, said cleaning head comprising an applicator assembly including a compressible porous body having an operative facing layer formed by a pile fabric, a liquid supply duct arrange to deliver such liquid to said porous body so that the liquid percolates through said porous body and said facing layer, a brush of relatively harder material than the facing layer arranged at at least one edge of said applicator assembly, and the facing layer of said applicator assembly being normally disposed so as to project outwardly, from the housing beyond the brush, the latter serving to limit inward displacement of the facing layer when in use.

Abstract
A cleaning head adapted for use on hard surfaces comprises a body (10) formed as two back-to-back housings (20) and (30) which are swivellably mounted on a suction tube (40). Housing (20) contains a liquid applicator assembly (21) which comprises a body (22) of porous material with a facing layer of pile fabric (23). A cleaning liquid is delivered through ducts (46) and (48) to the body 22 so as to spread uniformly across the pile fabric (23). A suction slot (29) adjacent to the applicator assembly (21) may be provided to pick up dry dirt. The housing (30) includes a liquid pick-up assembly (31) comprising a slot (32) between a pair of flexible blades (33a,33b).
