ABSTRACT:
A socket is provided on the upright portion of a vacuum cleaner for the insertion of the wand on the distal end of the accessory hose. The wand, which is normally inserted into the socket when the accessories are not being used, engages a linkage mechanism within the socket. The linkage mechanism closes a valve door within the suction stream when the wand is removed to close the suction passageway from the vacuum source to the base and open the suction passageway to the hose. The linkage mechanism opens the valve door when the wand is replaced to close the suction passageway to the hose and open the suction passageway to the base. The present invention automatically closes the suction passage from the floor engaging portion whenever the accessories are being used and assures that the suction connections are always in the proper position for floor cleaning or above-floor cleaning.
