A main rotary broom for a power sweeper machine is described having arrays of brushes disposed at angles relative to a central longitudinal axis of the broom wherein the angles further diverge from one another. When the broom is rotated in use, the brushes sweep debris upwardly away from the street surface and toward a central region above the mid-section of the broom for subsequent handling and collection. An improved integral plastic brush and process for making the brush component is further disclosed for use with the broom.
