In a vacuum cleaner nozzle (N) comprising one or more rear wheels (RW), a hinge (H3) is arranged to lift all one or more rear wheels (RW) from a floor (F) when a suction tube (ST) connected to the nozzle (N) is rotated around a longitudinal axis of the suction tube (ST), e.g. after the nozzle (N) has been rotated by more than 45 degrees by means of a further hinge (H2) in order to position a relatively short side of the nozzle at the front of the nozzle in the nozzle's motion direction so that the nozzle is able to clean relatively small spaces that could not be entered if a relatively long side of the nozzle is at the front of the nozzle in the nozzle's motion direction. If the one or more rear wheels (RW) comprise at least two rear wheels, the hinge (H3) is arranged for simultaneously lifting the rear wheels (RW) from the floor (F). Preferably, the hinge (H3) is bi-stable, to which end the hinge (H3) may be provided with magnets (M1-2, M3-4) or a bi-stable spring (S) to fix the hinge(H3) either in a first p
