Abstract
A vacuum cleaner includes a housing, a height adjust mechanism disposed on the housing and a height adjust motor, disposed within said housing that controls a height of the height adjust mechanism. A position element is mounted to said housing. A sensor processor, mounted to said housing, is in communication with the position element to provide a signal that relates to a position of the height adjust mechanism based at least in part upon data received from the position element. A controller processor, mounted to said housing, is in communication with the sensor processor for selectively controlling a height of the height adjust mechanism relative to a subjacent surface on which the vacuum cleaner is positioned. A height adjust mechanism height motor controller is in communication with the controller processor, for driving the height adjust motor to locate the height adjust mechanism in an appropriate position relative to the subjacent surface.
