ABSTRACT:
A power driven vacuum sweeper for thoroughly and rapidly removing padding and glued particles which remain attached to a floor after a worn-out carpet has been removed therefrom. The sweeper is characterized by having a cylindrical metal broom mounted on the front end of a frame and arranged for clockwise rotation to bite into and remove the padding and glued particles from the top surface of the floor as a pair of handlebars attached by a lever to the frame of the sweeper is moved forward and in and upward direction about a pair of wheels. The sweeper is further characterized in that the pair of wheels are mounted for a rocking sidewise movement about the frame when either wheel engages irregular high or low floor surfaces thereby allowing the thorough horizontal cleaning position of the entire width of the broom to be maintained under these adverse operating conditions.
