Vacuum cleaner
The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners. The first manual models, using bellows, were developed in the 1860s, and the first motorized designs appeared at the turn of the 20th century, with the first decade being the boom decade.
Central vacuum cleaner
The first introduction of a system similar to a central vacuum cleaner was in the late 19th century. A ducted machine that featured copper tubes connected from a bellows chamber, typically located in the basement, and extended to several locations throughout a building, was used in a select few homes at this time. Because of the machine’s cost and weak dust-removal capabilities, only a few of these units were ever sold in the United States.
