A vacuum cleaner, also known simply as a vacuum, is a device that uses suction, and often agitation, in order to remove dirt and other debris from carpets and hard floors.

The Hoover Company is a home appliance company founded in Ohio, United States, in 1915. It also established a major base in the United Kingdom; and, mostly in the 20th century, it dominated the electric vacuum cleaner industry, to the point where the Hoover brand name became synonymous with vacuum cleaners and vacuuming in the United Kingdom and Ireland. Hoover North America was once part of Maytag, but was sold by Maytag's new owners Whirlpool Corporation in 2007 to Hong Kong multinational manufacturing company Techtronic Industries for $107 million. Hoover International had already split from Hoover North America in 1993, and was acquired by Candy in 1995, which was acquired by Haier in 2019.
