In most cities, there are three common types of street sweeping technologies that are recognized within the industry. To most people just going about their day, it may look like all street sweepers operate the same, however, it’s important to realize that there are different technologies behind every sweeper for different industries and purposes of street sweeping.
These three common types of street sweeping technology are classified as Mechanical Broom Sweepers, Vacuum Sweepers, and Regenerative Air Sweepers. While each type of street sweeper achieves the same goal of removing debris from paths, they all have unique benefits for different types of debris and roads that they operate on!
Mechanical Broom Sweeper
Normally characterized by the large rotating broom at the rear end of the sweeper, this street sweeping technology flicks upcoming debris onto a conveyor that sends the debris into a hopper. Most mechanical broom sweepers are used for picking up heavier debris such as sand or gravel and are less effective at picking up finer material or penetrating cracks. Mechanical broom sweepers are highly utilized in the construction industry for construction services such as picking up heavy gravel and millings.
Think of it as a giant version of your home vacuum cleaner. Normally, vacuum sweepers remove surface debris using side brooms that move debris into the path of a highly suctioned air nozzle to free up loose particulars and transfer them directly to a containment center. You might have seen these as you pass by on the street! While they might pose a slight inconvenience, they are a great resource for municipal street sweeping and keeping storm drains clear and roadways safer!
A vacuum sweeper typically results in the removal of 99% of all particles underneath the suction nozzle and are highly utilized on uneven roads with potholes. These sweepers are commonly used for cleaning out street gutters with leaves, gravel, and small debris.
Regenerative Air Sweeper

This street sweeping technology was introduced in the mid-1960’s. Regenerative air sweepers are designed with an engine that powers a blower to blast air across the width of the sweeper. Similar to a vacuum sweeper, dirt and debris are sucked at one end of the sweeper into a hopper where the debris rests while air is cleaned by a dust separator before returning to the blast nozzle, creating a closed-loop air cycle. Most regenerative air sweepers are utilized for municipal sweeping like streets, parking lots, and dust control.
With new advancements, street sweeping technology is constantly being refined and improved to provide the most environmentally friendly methods of sweeping.
