In the 160 years since the mechanical street sweeper was patented, equipment has become much more sophisticated. No longer used just to keep streets free of vermin-attracting litter, sweepers that remove microscopic-sized pollutants are helping many communities meet stormwater requirements in all types of conditions and temperatures. Here is a summary of the most popular types. How it works: A main broom picks up debris that's sent to a conveyor and ultimately lands in a hopper. Major benefits: Uses less fuel than other types of sweepers because it doesn't require high horsepower airflows. It is not sensitive to high street crowns or rough damaged street surfaces. Able to remove larger and heavier debris than other technologies. All current available models may be off-loaded into trucks and containers for transport.
