Abstract
A nozzle base for a vacuum cleaner includes an upright front wall, an upright rear wall spaced from the front wall and having a suction air aperture, first and second upright side walls extending transversely between mutual end edges of the front and rear walls, respectively, and an upper wall joined to the front wall, rear wall, first side wall, and second side wall to define a downwardly opening chamber adapted to rotatably support an associated agitator therein. The upper wall has an intermediate section above the suction air aperture, a first wall section tapering downward from the intermediate section in a direction toward the first upright sidewall, and a second wall section tapering downward from the intermediate section in a direction toward the second upright sidewall. The second wall section terminates at a height below an uppermost extent of the agitator, and the second wall section including a recess adapted to conform generally to the agitator.
