Vacuum cleaner head

A surface treating head in the form of a floor tool for a vacuum cleaner includes a main body, a suction cavity and an outlet. The suction cavity includes first and second suction channels, bounded on both sides by respective working edges. A fluid flow path extends from the first suction channel to the second suction channel and from there to the outlet. The plurality of suction channels permits effective pick-up of dirt. To enable the surface treating head to be used to treat both carpeted floor surfaces and hard floor surfaces, the surface treating head may be provided with a brush unit and a drive mechanism for moving the brush unit between a stowed position and a deployed position.

Surface treating head

A surface treating head includes a main body; a brush unit; and a drive mechanism for moving the brush unit relative to the main body between a stowed position and a deployed position. The drive mechanism includes a pressure chamber and a valve unit for varying the pressure within the chamber. The valve unit includes a housing, a valve located within the housing and, disposed on the housing, an actuator moveable relative to the housing through engagement with a surface to be treated for operating the valve and at least one surface engaging member extending downwardly beyond the actuator. The housing is moveable relative to the main body to maintain the surface engaging member in contact with the surface to be treated.

A surface treating head includes a main body, a suction cavity in the main body including first and second suction channels, each of which is bounded on one side by a working edge, an air duct interposed between the first and second suction channels for conveying air towards the working edges, a brush unit and a drive mechanism for moving the brush unit between a stowed position in which the air duct is open to the atmosphere and a deployed position in which the air duct is closed.
