Abstract
An agitator assembly having a spindle having a first end, a second end, and a longitudinal axis. One or more primary agitators are attached to the spindle between the first end and the second end, and edge agitators are attached in a generally circumferential pattern around the spindle'"'"'s first end. In one aspect, the edge agitators may be arranged at different inclination angles. In another aspect, the edge agitators may be attached on offset circumferential lines. In another aspect, at least one of the edge agitators is more flexible than a primary agitator. In another aspect, the first end has an edge cleaning assembly that is attached to the spindle and rotationally fixed relative thereto by one or more rotationally interlocking structures formed integrally with the edge cleaning assembly. Also provided is a cleaner having a housing and a spindle, with a window through the housing to view the first end of the spindle and substantially no other parts of the spindle. Also provided is an agitator assembly with a spindle, an edge cleaning assembly attached to the spindle, and edge agitators mounted to the edge cleaning assembly.
