Electrolux Model V, first vacuum sold by Electrolux Corp USA 1924-1928.

The first introduction of a permanent system similar to a residential central vacuum cleaner was in the late 19th century. A ducted machine featuring copper tubes connected from a bellows chamber, typically located in the basement and extended to several locations throughout a building, was used in a select few homes.
This test was essentially the first documented pressure gauge. In 1647 Valerianus Magnus published his Demonstratio ocularis , in which he claims to have proved the existence of the vacuum in the court of the king of Poland, Ladislaus IV , in Warsaw by means of an experiment identical to that carried out by Torricelli three years earlier.
