Abstract
A vacuum cleaner having edge cleaning features comprising a cleaner body with a floor contacting suction chamber and a suction duct leading from the chamber, an edge auxiliary cleaning chamber at one end of the suction chamber and communicating through a port with the suction duct, a valve within the cleaner body movable between open and duct restricting positions for selective full nozzle cleaning and edge cleaning with suction through the auxiliary cleaning chamber when the valve is open and operating means accessible from the exterior of the cleaner for the moving of the valve between said positions.

A vacuum cleaner having edge cleaning features, said vacuum cleaner comprising:
- a cleaner body having a surface contacting suction chamber, a suction duct leading from said chamber, and an edge auxiliary cleaning chamber at an end of said suction chamber communicating through a port with said suction duct;
- an internal valve movable between open and closed positions for controlling air flow both from said suction chamber and auxiliary cleaning chamber to said duct;
- means for limiting the movement of said valve to provide when said valve is in the open position maximum air flow through said auxiliary chamber for maximum edge cleaning and limited substantial air flow through said suction chamber for limited center cleaning, and provide when said valve is in the closed position no air flow through said auxiliary cleaning chamber and full air flow through said suction chamber for maximum center cleaning;
- and operating means accessible from the exterior of said cleaner for selectively moving said valve to said open and closed positions.
A vacuum cleaner having edge cleaning features, said vacuum cleaner comprising:
- a cleaner body having a surface contacting suction chamber and a suction duct leading from said chamber;
- a rotatably driven brush positioned in said suction chamber for agitating the surface to be cleaned;
- means defining an edge auxiliary cleaning chamber at an end of said suction chamber communicating through a port with said suction duct;
- an internal valve movable between open and closed positions for controlling flow both from said suction chamber and auxiliary cleaning chamber to said duct;
- means for limiting the movment of said valve to provide when said valve is in the open position maximum air flow through said auxiliary chamber for maximum edge cleaning and limited substantial air flow through said suction chamber for limited center cleaning, and provide when said valve is in the closed position no air flow through said auxiliary chamber and maximum air flow through said suction chamber for maximum center cleaning;
- and longitudinally movable operating means accessible from the exterior of said cleaner for selectively moving said valve to said open and closed positions.
