A street sweeper or streetsweeper is a person or machine that cleans streets, usually in an urban area.
Urban job
Street sweepers have been employed in cities since sanitation and waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later water hoses were used to wash the streets.
Mechanized sweeping
The first mechanical street sweeper invented was invented by C.S. Bishop, patented on September 4, 1849. A mechanical street-sweeper is mounted with several rotating disks and/or drums covered in stiff wire bristles.
Modern sweepers
Modern street sweepers are equipped with water tanks and sprayers used to loosen particles and reduce dust. The brooms gather debris into a main collection area from which it is vacuumed and pumped into a collection bin.
A regenerative air street sweeper uses forced air to create a swirling knifing effect inside a contained sweeping head and then uses the negative pressure on the suction side to place the road debris inside a hopper. The debris laden air is then separated (pm 10 is not filtered out) and reused to start the process anew. Many regenerative air sweepers are AQMD certified by the company who manufactures them and can pick up particles as small as 10 micrometres or less (PM-10), a leading cause of stormwater pollution.
The machine has occasionally been referenced in popular music, including the blues tune "Big Yellow Street Sweeper," (Root 6, Root Boy Slim, Ichiban Records, 1991). That was a true story about Root Boy Slim taking an unauthorized joy ride in the machine when he found himself locked out of his car in Atlanta, Ga. in the mid-1980s.
