The invention is a floor care appliance such as vacuum cleaner having a pivoting valve arrangement for maintaining suction from the appliance housing to the suction nozzle. A valve is provided for sealing off suction to the suction nozzle when the housing is in the upright or off the floor mode position. When the housing is in the upright position maximum suction is directed to the accessory hose. When the housing is moved to the floor mode maximum the valve is moved to the open position and suction is directed to the suction nozzle for floor cleaning. The valve is located in a valve body assembly pivotally connected over the rear duct of the suction nozzle. The valve body is partially located in the housing and pivots with the housing. A roller and cam arrangement cause the valve located in the valve body to move back and forth between the open and closed positions.
