ABSTRACT:
A vacuum cleaner nozzle having a first nozzle part (11) which has brush elements (23) or the like facing the floor and a second nozzle part (25) which is movably arranged with respect to the first part (11) and which has at least one suction opening (27) through which air flows to an outlet tube (13) connected to the nozzle. The second nozzle part (25) is supported by the first nozzle part (11) by means of a resilient element (31). The resilient element maintains the second part (25) above the floor when the nozzle is moved on a hard surface and allows the second part (25) to move toward the floor when the nozzle is moved on a soft surface, such as a soft carpet.
