ABSTRACT:
A pick-up head is formed by a housing which defines a broom chamber rearward of an associated air pressure chamber and its associated blast orifice. The broom is rotated in a direction to impel debris from a surface in the same direction as air emitted from the blast orifice toward an associated air suction chamber. Due to the latter arrangement, debris which is "tacky" which is "stuck" onto the surface, or which is too heavy to be moved into the suction air stream by the blast air alone is impelled at a relatively high entrainment velocity toward and into the air suction stream which continues the movement of this debris for eventual discharge into an associated hopper.
