A blower head, comprising a frame, a brush rotatably supported by the frame, a sweeper drive adapted for rotating said brush to sweep a surface, and a blower unit adapted for removing swept-up particles away from the surface. The frame includes a mouth portion and a throat portion. The brush is rotatably supported by the frame within the mouth portion. The sweeper drive rotates the brush to sweep particles such as snow or ice on a surface toward the frame. The mouth portion and the throat portion are constructed and arranged to funnel swept-up particles from the mouth portion and into the throat portion and the blower unit positioned therein. The blower head further includes an exit chute. The blower unit creates a pressure differential between the mouth portion and the exit chute sufficient to draw the swept-up particles from the mouth portion and into the throat portion, and to blow the swept-up particles out through the exit chute. The invention further includes a method for scavenging surfaces, such as surfaces packed with snow and/or ice, comprising the steps of rotating a brush to scavenge and sweep a surface, drawing swept-up particles away from the surface, and blowing the swept-up particles out through an exit chute.
