Charles Brooks, a resident of Newark, N.J, is credited with inventing the street sweeping trucks in 1896 with revolving brushes.

Street sweeping was a manual job until he invented the self-propelled street sweeper.

—Street sweeping was often a manual labor job in Brooks' time. Keeping in mind that horses and oxen were the main means of transportation — where there is livestock, there is manure. Rather than stray litter as you might see today in the street, there were piles of manure that needed to be frequently removed regularly. In addition, garbage and the contents of chamber pots would end up in the gutter.

The task of street sweeping was not carried out by mechanical equipment, but rather workers who roamed the street sweeping garbage up with a broom into a receptacle. This method clearly required a lot of labor, although it did provide employment.
