A brushroll for a vacuum cleaner includes a dowel defining a central rotational axis about which the brushroll rotates, at least one bristle stiffener, a plurality of first bristles protruding from the dowel adjacent to the bristle stiffener, and a counterbalance which is positioned relative to the bristle stiffener to rotationally balance the brushroll, wherein the cross-sectional shape of the dowel is asymmetrical.
