Abstract

A vacuum cleaner includes a base and a brushroll positioned within the base. The base has a suction opening and is configured to move along a surface to be cleaned. The brushroll is rotatable relative to the base about an axis, and the brushroll includes a first end, a second end, an inflection point located between the ends, and a material that protrudes radially away from the brushroll. The material extends between the first end and the second end and wraps around the brushroll with a pitch. The material wraps in a first direction between the first end and the inflection point and wraps in a second direction between the inflection point and the second end.
