The
Industrial Revolution caught on with the United States gradually, but
when it became widespread, the manufacturing sector displaced many
people whose skills could be replicated by machinery more
efficiently. However, the introduction of the mechanical sweeper in
both England and the United States in the 1840s did not replace the
human street sweeper, largely because the innovation did not seem
anything revolutionary back then,
Things
changed with the introduction of a motor-driven pickup street sweeper
by Elgin Sweeper in Illinois, which was first purchased in Boise,
Idaho in 1913 right after a demonstration. For Boise's street
commissioner, the selling point was the amount the city would save. A
horse-drawn sweeper would cost $2,716.77 more. Patents to an enhanced
version of the original sweeper were not filed and issued until 1917.
It
was in the 1970s, however, when the street sweepers received a major
upgrade. Until then, the sweeper can only collect large particles
such as fallen leaves and various urban refuse. The roads looked
neat, but they remain dirty with smaller particles that mix with
rainwater when showers come.
Therefore,
it was the need to minimize pollution in water collected by storm
drains that pushed the street sweepers of today to be more
sophisticated and effective as they are now able to collect small
particles of debris. Nowadays, Elgin street sweepers are also
equipped with water tanks and sprayers to help the sweeping devices
to reduce dust.
