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.
Kirby Company
The first Kirby vacuums were designed by James B. Kirby (1885–1971) for George Scott and Carl Fetzer after World War I, although the Kirby name was not used on a vacuum cleaner until the 1930s. James Kirby invented the "vacuette" circa 1920, and their primary competitors were The Hoover Company and The Eureka Company which both began operations in 1909, and Bissell who originally built carpet sweepers beginning in 1876. Their primary European competitor was Electrolux in 1924, while Dyson, Miele and Sebo followed in the 1980s.
