ABSTRACT:
A beater brush for a vacuum cleaner includes a cylindrical dowel having at least one groove helically disposed in an outer periphery thereof for receiving a bristle strip. The bristle strip has a bristle support section and a beater bar integrally formed with a hinge disposed therebetween. In the bristle strip's molded position, the beater bar is disposed a distance from the bristle support section to allow bristle tufts to be inserted in apertures formed in the bristle support section. After the bristle tufts are secured to the bristle support section, the beater bar is swung into position abutting the bristle tufts so as to impart kinetic energy thereto.
