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
1930 saw the introduction of the world's first handheld vacuum cleaner, the Hoover Dustette. The good design and exceptional durability of these machines mean many are still in service today, some at over 80 years old.
