Street sweeper
A Street sweeper is a person or machine that cleans streets, usually in an urban area.
A street-sweeping person might use a broom, or water hoses, or both, to clean off litter and filth that accumulates on streets. A mechanical street-sweeper converts the broom to several rotating disks or drums covered in bristles, with which is sweeps away dirt after spraying the street with water.
