Street sweepers are monster machines that run along the curbs of city streets.
Some machines use steel brushes to sweep leaves, litter, twigs, and other stuff into a “hopper.” Other street sweepers use vacuums, instead of brushes, to suck up the stuff.
Once the gunk is collected, it is properly thrown away. Street-sweeper machines are a good way for cities to “lose the ooze.”
A street sweeper machine cleans up in Preston, England. Blimey! That’s why the sweeper is going down the left side of the road. Street sweepers help to keep gunk out of storm sewers.
