If
you look at mechanized street sweepers, they somewhat seem too
“ordinary”. To the average observer, they only seem to be trucks
fitted with brooms that rotate nonstop.
However,
mechanized street sweepers are in fact technological marvels
underneath their average appearances. There are two main types of
sweepers: the wet and dry ones. Wet sweepers are equipped with large
water tanks and sprayers intended to loosen caked dirt, while the dry
variants sport specialized brooms.
