air passage means accommodated within said housing adapted for connection to a source of suction and having at least one opening for collection of liquid by suction from the surface;
operating means for effecting movement of the agitating means relative to said housing between an operative position and an inoperative position; and
valve means operatively connected with said agitating means for permitting delivery of the cleaning liquid by said delivery means when the agitating means is in its operative position and preventing delivery of the cleaning liquid when the agitating means is in its inoperative position.

Abstract
In a cleaning head (10) of the kind having agitating means (26) engageable with a surface to be cleaned for agitating cleaning liquid thereon, and collecting means (25) for collection of liquid from the surface by suction, the agitating means (26) and collection means (25) are relatively movable such that one or the other is selectively prominently engaged with the surface being cleaned. In a preferred arrangement the agitating means (26) is movable relative to a housing (11) of the cleaning head while the collecting means (25) is fixed in position relative to the housing (11). Cleaning liquid is delivered to the agitating means through a passage (45) which is closed by a pad (70) at the upper side of the agitating means (26) when the latter is in its raised position. Movement of the agitating means (26) between its raised and lowered positions is controlled by means of a foot pedal (65).

5. A cleaning head for surface cleaning comprising:
-
a housing having a front end and a rear end; agitating means carried by said housing and engageable with a surface to be cleaned; delivery means for delivery of a cleaning liquid to the surface to be cleaned in the region of the agitating means, said agitating means adapted for agitating the cleaning liquid thereon; air passage means adapted for connection to a source of suction; collecting means disposed between said agitating means and said front end of said housing, engageable with the surface and communicating with said air passage means, for collection of liquid from the surface by suction; operating means for effecting movement of the agitating means relative to said housing between operative and inoperative positions in a direction which, in use, is generally perpendicular to the surface being cleaned, whereby said agitating means and said collecting means are selectively disposed to co-operate with the surface; and support means carried by said housing for assisting in supporting the head on said surface being cleaned, wherein said support means comprises rear support members disposed at said rear end of said housing and forward support members disposed adjacent to said agitating means, said forward and rear support members being disposed such that, when the agitating means is in its operative position, the head, when in use, is supported partly on said rear support members and partly on said agitating means, and when the agitating means is in its inoperative position, the head, when in use, is supported on said rear support members with said agitating means substantially clear of the surface. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
