CA 2311984

A suction nozzle unit for a vacuum cleaner unit includes a casing formed with a suction inlet, a pair of front wheels located at the front of the casing, and a pair of rear wheels located at the rear of the casing. The suction nozzle unit also includes a shaft pin for rotatably supporting the front wheels and an arrangement, for moving the casing up and down relative to the shaft pin so as to raise and lower the front end of the casing relative to the surface to be vacuumed. As a result the front end of the unit can be moved up and down as necessary depending, for example, on the depth of pile of a carpet being vacuumed, thereby increasing ability of the unit to travel over the carpet during vacuuming.
