ABSTRACT:
A convertible vacuum cleaner operable in both on-the-floor and above-the-floor cleaning operations is shown. Depending upon the location of the handle which is pivotally supported by the vacuum foot, a conversion valve interconnected to the handle automatically converts the vacuum between on-the-floor and above-the-floor cleaning operations. The conversion valve includes a flapper valve member which is actuated between a first position blocking fluid communication between the vacuum motor and the brush roll chamber and a second position blocking fluid communication between the vacuum motor and the accessory hose. The valve member is actuated between these two positions by a pin and actuator arm provided on the pivotally mounted valve member. The pin is received in a contoured groove formed on the motor housing and the motor housing is securely mounted to the handle and pivotally mounted with respect to the foot and valve member. As the handle is tilted between the substantially upright position and a tilted position, the flapper valve member is actuated between the first and second positions.
