Street sweepers have been employed in cities as "sanitation workers" 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.
Newer street sweepers are capable of collecting small particles of debris. Many street sweepers produced today are PM10 and PM2.5 certified, meaning that they are capable of collecting and holding particulate matter sized less than 10μm and even down to 2.5μm. Despite advancements in street sweeping technology, the mechanical broom type street sweeper accounts for approximately 90 percent of all street sweepers used in the United States today. In 2018, Boschung, a Swiss street sweeper manufacturer, launched the Urban-Sweeper S2.0, the first fully electric street sweeper releasing 0 (zero) emissions.
The need for rubbish to be removed from roads in built-up areas has existed for centuries.
Sometimes a local law in a town or city ordered the owner of occupier of each address to clean the length of that road that passed his address.
Mechanical sweepers in the United Kingdom
By the 1840s, Manchester, England, had become known as the first industrial city. Manchester had one of the largest textile industries of that time. As a result, the robust metropolis was said to be England’s unhealthiest place to live. In response to this unsanitary environment, Joseph Whitworth invented the mechanical street sweeper. The street sweeper was designed with the primary objective to remove rubbish from streets in order to maintain aesthetic goals and safety.
Mechanical sweepers in the United States
The very first street sweeping machine was patented in 1849 by its inventor, C.S. Bishop. For a long time, street sweepers were just rotating disks covered with wire bristles. These rotating disks served as mechanical brooms that swept the dirt on the streets.
A common misconception is that Charles Brooks invented the street sweeper in America in 1896. Brooks' design, far from being the "first street sweeper," was just a variation of what already existed, and the patent for it was among the more than 300 street sweeper patents issued in the United States before 1900. Most 19th-century sweepers, including the one in Brooks' patent, were horsecarts with no engine on board. The wheels on the cart turned gears or chains which drove the brush and belt. The first self-propelled sweeper vehicle patented in the US, driven by a steam engine and intended for cleaning railroad tracks, was patented in 1868, patent No. 79606. Eureka C. Bowne was the first known woman to get a patent for a street sweeper, in 1879, patent No. 222447. "Her success was great", wrote Matilda Joslyn Gage in The North American Review, volume 136, issue 318, May 1883.
John M. Murphy called at the offices of American Tower and Tank Company in Elgin, Illinois, in the fall of 1911. He had a plan of a motor-driven pickup street sweeper. The American Tower and Tank Company had been formed in 1903 by Charles A. Whiting and James Todd. They called in a recently acquired silent partner, Daniel M. Todd, and it was decided to hire Murphy and begin the development of his idea. That started what has become the Elgin Sweeper Company.
After two years of trial, development, experimentation, and research, a sweeper was achieved which Murphy was satisfied performed all of the sweeping functions in the manner he had envisioned – one which partners James and Daniel M. Todd and Charles A. Whiting were willing to risk a reputation gained from 30 years' manufacturing experience.
In the fall of 1913, the city of Boise, Idaho, purchased the first Elgin Sweeper, following a demonstration. Boise Street Commissioner, Thomas Finegan, made a comparison showing a savings of $2,716.77 from the Elgin motorized sweeper when used rather than a horse-drawn sweeper.
Following its introduction and initial sales, Murphy continued improving his sweeper. In 1917, US patents were filed and issues for J. M. Murphy, Street Sweeping machine No. 1,239,293.
The goal of simple debris removal did not change until the 1970s, when policymakers begun to reflect concern for water quality. In the United States, the lag time in which street sweepers responded can be pinpointed to the Runoff Report of 1998. As older street sweepers were only effective in removing large particles of road debris, small particles of debris remained behind in large quantities. The remaining debris was not seen as an aesthetic issue because rain would wash them away. Today, small particles are known to carry a substantial portion of the stormwater pollutant load.
Street sweeping can be an effective measure in reducing pollutants in stormwater runoff. The Environmental Protection Agency considers street sweeping the best practice in protecting water quality.
