Generally speaking, there are three types of street sweeping technologies that are recognized within the street sweeper industry. These technologies can be identified as Mechanical Broom Sweepers, Vacuum Sweepers and Regenerative Air Sweepers. These three fundamental technologies can each have unique variations to the technology that is implemented by a sweeper manufacturer. An example of this would be the "high-efficiency" modification.
Sweepers of all types commonly use gutter brooms to move dirt and debris into the path of the pick-up mechanism of the sweeper. To control fugitive dust, a series of water nozzles are typically used to spray a mist of water around brooms and within the sweeper hopper.
Vacuum Street Sweepers
Vacuum sweepers use an engine powered fan to create suction. Typically, a windrow broom moves dirt into the path of a vacuum nozzle, where dirt and debris are sucked into a hopper. The large volume of the hopper causes the heavier material to fall, while a screen traps lighter material such as leaves, before the air is exhausted. Vacuum sweepers are better at picking up finer material than mechanical sweepers, but share many of the same disadvantages, because the windrow broom is less effective at penetrating cracks and potholes in the street, and the suction nozzle typically only covers about 1/3 of the width of the sweeping path. Vacuum exhaust can also emit a significant amount of dust to the atmosphere.
