    (54) Valve for cleaning implements


    (57) The invention relates to a brush (10) suitable to be connected to a conventional hose and including an automatic water shut-off valve means (28) which acts automatically when the brush is removed from the surface being cleaned. This is achieved by the provision of a seat (26) in a chamber (24) containing the valve means, wherein the valve means is continuously biased toward the seat of the water under pressure so that the valve means prevents water flow when in contact with seat, and operating means (62, 60, 46) to selectively force the valve means away from the seat and thereby allow water flow.
