Introduction and Machine Specifications
The PS-27 is many times faster than conventional cleaning with a push broom. The side broom allows for cleaning along
curbs or walls and in corners. There is no engine or motor, no noise, and no odor. The push sweeper requires no mainte-
nance. The hopper can be emptied easily and rapidly.
The PS-27 can be used anywhere, anytime....indoors or outdoors for concrete, tile and commercial carpets.
