Abstract: A cleaning appliance vacuum cleaner includes a main body having a rear portion and a roller structure such as side wheels arranged to allow the main body to travel across a floor surface. In normal use, the rear portion is spaced from the floor surface. The rear portion carries a wheel arranged so that, if the main body is tilted so that the rear portion is brought towards the floor, the wheel contacts the floor surface. Thus, the cleaner may be used in a tipped-back position without causing damage to the floor surface as the cleaner is dragged along by the user by a hose attached to the main body. The size and position of the wheel is determined so that, when the cleaner is tipped back, the center of gravity of the main body acts to return the main body to an upright position.
