Abstract
An upright vacuum cleaner is provided having a suction nozzle height adjustment arrangement controlled by a rotary mode control member located on the upper housing. The rotary mode control member controls a suction nozzle height adjustment motor and a rotary agitator drive disconnect arrangement. A wheel tensioner located on an idler arm is operatively connected to a cam on the suction nozzle height adjustment motor which tensions and de-tensions the agitator drive belt to control the rotary agitator. The rotary mode control member could have discrete settings for the various floor surfaces to be cleaned including bare floors and carpet of varying pile heights. Alternately, the rotary mode control member could be variable so that an infinite number of suction nozzle height settings can be selected.
