Abstract
A vacuum cleaner includes a base assembly with an upper housing, an agitator mounted in fixed position relative to the upper housing, an agitator height control mechanism for selectively adjusting the vertical height of the agitator relative to the surface to be cleaned, and a sole plate. The sole plate includes a suction nozzle opening for the base assembly and during operation of the agitator height control mechanism, the sole plate moves relative to the upper housing so that the distance between the suction nozzle opening and the surface to be cleaned remains essentially the same, regardless of the position of the agitator.
