Abstract
A vacuum cleaner brushroll characterized by a bristle tufted arrangement that forms multiple dwell positions around the brushroll. In each dwell position, the majority of bristle tufts along the length of the spindle are out of sweeping contact with the carpet which allows the carpet to drawn upwardly toward the mouth of the vacuum cleaner nozzle. The up and down carpet movement that occurs during brushroll rotation enhances its cleaning performance.
