ABSTRACT:
A tubular type brush for use in a cleaning machine includes a generally cylindrical driver tube adapted to be rotated about its axis for use in cleaning an adjacent floor surface. The driver tube has an exterior surface with circumferentially and axially located bristles extending outwardly therefrom. The bristles extend, when the driver tube is in an at rest position, in a direction which is closer to parallel with the driver tube exterior surface than perpendicular to the driver tube exterior surface. The bristles have tips which move outwardly from the driver tube exterior surface as the tube rotates, with the degree of the outward movement being dependent, at least in part, upon rotary speed of the driver tube.
