ABSTRACT:
A vacuum cleaner is provided with a wheel housing having at least one axle bracket extending therefrom along a transverse axis and at least one axle bracket-receiving socket formed in a foot of the vacuum cleaner whereby the socket slidably receives and pivotally mounts the at least one axle bracket. The wheel housing is thereby pivotally mounted to the foot. A height adjustment mechanism is provided with the wheel housing having an actuator having a bearing shaft and a bearing sleeve with a longitudinal bore. The longitudinal bore of the bearing sleeve receives the bearing shaft to rotatably mount the actuator. A detent mechanism is provided between the bearing shaft and the bearing sleeve to releasably mount the actuator to the foot. The actuator can be adapted to release upon encountering abnormal forces applied against the vacuum cleaner.
