vacuum cleaner, also known simply as a vacuum (or a hoover in the UK), is a device that uses suction, and often agitation, in order to remove dirt and other debris from carpets, hard floors, and other surfaces. The dirt is collected into a dust bag or a plastic bin. Vacuum cleaners, which are used in homes as well as in commercial settings, exist in a variety of sizes and types, including stick vacuums, handheld vacuums, upright vacuums, and canister vacuums. Specialized shop vacuums can be used to clean both solid debris and liquids. Name Although vacuum cleaner and the short form vacuum are neutral names, in some countries (UK, Ireland) hoover is used instead as a genericized trademark, and as a verb. The name comes from the Hoover Company,[2] one of the first and most influential companies in the development of the device. In New Zealand, particularly the Southland region, it is sometimes called a lux, likewise a genericized trademark and used as a verb.[3][4] The device is also sometimes called a sweeper although the same term also refers to a carpet sweeper, a similar invention. History An early hand-pumped vacuum cleaner The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners.[5] 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. Manual vacuums Main article: Manual vacuum cleaner Patent model of Daniel Hess's carpet sweeper In 1860, a manual vacuum cleaner was invented by Daniel Hess of West Union, Iowa. Called a "carpet sweeper," it gathered dust with a rotating brush and had bellows for generating suction.[6][7] Another early model was the "Whirlwind", invented in Chicago in 1868 by Ives W. McGaffey. The bulky device worked with a belt-driven fan cranked by hand that made it awkward to operate, although it was commercially marketed with mixed success. [8] A similar model was constructed by Melville R. Bissell of Grand Rapids, Michigan in 1876, who also manufactured carpet sweepers.[9] The company later added portable vacuum cleaners to its line of cleaning tools. Powered vacuum cleaners Further information: Hubert Cecil Booth § Vacuum cleaner, and David T. Kenney Housemaid using "dedusting pump", c. 1906 The end of the 19th century saw the introduction of powered cleaners, although early types used some variation of blowing air to clean instead of suction.[10] One appeared in 1898 when John S. Thurman of St. Louis, Missouri, submitted a patent (U.S. No. 634,042) for a "pneumatic carpet renovator" which blew dust into a receptacle.[11] Thurman's system, powered by an internal combustion engine, traveled to the customer's residence on a horse-drawn wagon as part of a door-to-door cleaning service. Corrine Dufour of Savannah, Georgia, received two patents in 1899 and 1900 for another blown-air system that seems to have featured the first use of an electric motor. credit: wiki @bobnizam sufferfly@gmail.com
