Abstract
A changeover valve, for an upright vacuum cleaner, comprises a movable valve member (31) connected via a flexible duct to a dirt separator of the cleaner, and a valve body (30) having inlet ports (32, 33) connected, respectively, to an air inlet in the underside of a floor-engaging unit of the cleaner and, via a flexible hose, a suction nozzle of the cleaner. The valve member (31) is movable relative to the valve body (30) for selective alignment with either of the inlet ports (32, 33).
