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.
The Hoover Company
The first upright vacuum cleaner was invented in June 1908 by Canton, Ohio department store janitor and occasional inventor James Murray Spangler (1848–1915). Spangler was an asthmatic, and suspecting the carpet sweeper he was using at work was the cause of his ailment, he created a basic suction-sweeper by mounting an electric fan motor on a Bissell brand carpet sweeper then adding a soap box and a broom handle. After refining the design and obtaining a patent for the Electric Suction Sweeper he set about producing it himself, assisted by his son, who helped him assemble the machines, and his daughter, who assembled the dust bags. Production was slow, just two to three machines completed a week.
