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.<ref>{{cite web|title=A Brief History of Manchester|url=http://manchesterhistory.net/manchester/history/earlyhistory.html}}</ref> 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.<ref name="Pitt2004">Pitt R, Bannerman R, Sutherland R, 2004.
