The vacuum cleaner was invented in 1860 by Daniel Hess. It was later improved by inventors such as Ives W. McGaffey and Melville Bissell. These units were often bulky and difficult to move. In 1921 the Electrolux Company manufactured the first vacuum that was modeled to lie on the floor and be moved via wheels. This became the standard, and is still used in vacuum cleaners today.
