Lower labor costs by sweeping up to 15,500 square feet per hour on carpet and hard floors, indoors or outside. Clean up against walls and curbs with the 15" side broom that sweeps debris towards the dual counterrotating main brooms. Exceptional dust control. The Sidewinder 27 MB's vacuum fan pulls small debris into the filtration system. A manual shaker knocks debris down into the hopper keeping the filter working longer.
