Abstract
A floor care apparatus includes a housing having a nozzle assembly with a suction inlet and a canister assembly. A dirt collector and suction generator are carried on the housing. The apparatus further includes a wand having an inlet opening and a sealing element for sealing that inlet opening when the wand is held in a storage position. Additionally, the apparatus includes a valve and an airflow conduit system. The airflow conduit system provides fluid communication between the suction inlet, the inlet opening, the valve, the dirt collector and the suction generator. The valve is selectively displaceable between a closed position whereby the suction inlet is sealed off from fluid communication with the suction generator and an open position whereby the suction inlet is provided in fluid communication with the suction generator.
