Abstract: A suction nozzle for a vacuum cleaner includes a suction chamber; an outlet duct; an underside for engaging a surface to be cleaned; a main suction opening in the underside, which opens into the suction chamber; an auxiliary suction path which opens into the suction chamber; and a bleed path in fluid communication with the outlet duct. The suction nozzle further includes a valve mechanism arranged to open and close the auxiliary suction path and the bleed path, the valve mechanism being movable between a first configuration in which the auxiliary suction path is closed and the bleed path is open, a second configuration in which the auxiliary suction path is open and the bleed path is closed, and a third configuration in which both the auxiliary suction path and the bleed path are closed.

Abstract: A surface treating head comprising a suction cavity having a suction cavity opening bounded by a front working edge and a rear working edge, at least one of the front and rear working edges being moveable between a first position in which the suction cavity opening is at a maximum and a second position in which the suction cavity opening is at a minimum, an actuating mechanism comprising a user-operable actuator for actuating at least one of the front and rear working edges between the first and second positions, and one or more air bleed vents, wherein actuation of the actuating mechanism causes the one or more air bleed vents to open and close.
