Abstract:
1. A vacuum cleaner comprising: a base assembly adapted for movement along a surface to be cleaned, and having an upper housing comprising an agitator chamber defined by a first peripheral wall extending around at least a portion of the agitator chamber and a working air conduit adapted to be fluidly interconnected with a suction source; an agitator mounted within the agitator chamber in fixed position relative to the upper housing; an agitator height control mechanism for selectively adjusting the position of the upper housing relative to the surface to be cleaned to thereby adjust the vertical height of the agitator relative to the surface to be cleaned; and a sole plate comprising a suction nozzle opening in register with the agitator chamber and a second peripheral wall in alignment with the first peripheral wall, wherein the sole plate is coupled to the upper housing for movement between at least a first position and a second position, wherein, as the position of the upper housing relative to the surface to be cleaned is adjusted, the sole plate moves between at least the first and second positions; wherein, as the sole plate moves between at least the first and second positions, the first and second peripheral walls remain in alignment with one another.
