Abstract
The invention disclosed herein relates to an improved vacuum cleaner comprising a foot, a handle pivotally mounted to the foot, and a vacuum motor mounted to one of the handle and the foot. The foot has a suction inlet fluidly connected to the vacuum motor and an agitator brush rotatably mounted to the foot. The improvement relates to a wheel assembly comprising a housing, an axle mounted to the housing and at least one wheel rotatably mounted to the axle. The housing has an integrally-molded flange extending therefrom. The wheel assembly rollably supports the vacuum cleaner on a floor surface. A channel is formed in the foot and is adapted to pivotably mount the housing flange for movement between a first and a second position. In the first position, the wheel assembly supports the suction inlet at a first distance relative to the floor surface. In the second position, the wheel assembly supports the suction inlet at a second distance therefrom.
