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.

In 1910 the Star Vacuum Cleaner was patented in the U.K. (#18,899), consisting of a concertina-like drum that was pushed up and down the handle to suck dust through the cleaning head on top; the initial price was 54 shillings; it was discontinued in 1938.
