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. The device is also sometimes called a sweeper although the same term also refers to a carpet sweeper, a similar invention. In New Zealand, particularly the Southland region, it is sometimes called a lux, likewise a genericized trademark and used as a verb. The name comes from the Hoover Company, one of the first and more influential companies in the development of the device. Specialized shop vacuums can be used to suck up both solid matter and liquids.Īlthough 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. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models-small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dirt before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. The dirt is collected by either a dustbag or a cyclone for later disposal.
