ABSTRACT:
A power brush e.g. for a vacuum cleaner or street sweeper has its bristle bodies swivelably mounted on a member which is given an orbital movement so that the eccentric axes of the bristle bodies with respect to their swivel axis induces an additional oscillatory motion of each bristle body as it moves in the orbital path generated by the motion of the member on which its carrier is mounted.
