Abstract
A handle for a wand of a vacuum cleaning appliance includes a handgrip portion and a conduit for receiving an air flow. The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. To vary the air flow into the conduit, the control mechanism includes a first manually operable actuator located on the handle for moving both of the first and second valves away from the aperture, and a second manually operable actuator is located on the handle for moving only one of the first and second valves away from its respective portion of the aperture.
