Portable The Hoover Portable was launched by Hoover in 1963. It is a "Suitcase" type canister that did not have wheels; it would tugged around with by the user. When finished, the hose, attachments, and power cord would be stored inside the machine. In 1969, Hoover added wheels to the Portable. The Portable was manufactured until 1978. Also, it used the same motor as the Hoover Dial-A-Matic, the first clean-air upright. The Constellation In 1954, Hoover introduced the Model 82 Constellation. It was a radically new design in cylinder and tank cleaners. Designed by Henry Dreyfuss, it represented America's obsession with the space race. Its spherical shape resembled the planet Saturn and impersonated developing space technology. Its most memorable attribute was the ability to "walk on air", which eliminated the need for casters, wheels or runners. The cleaner was made mobile by using its exhaust air, which caused the cleaner to lift from the floor and float behind the user (starting with the Model 84). This was an engineering marvel in and of itself. The Constellation cleaner remained extremely popular in its close to 25-year run, with minor design modifications. The machine was discontinued in the mid-1970s with the introduction of the Hoover Celebrity; however, the Constellation was still produced in the UK well into the 1980s. The machine was so fondly remembered that it was reintroduced and sold from 2006 to 2009. Model 28 Introduced in 1946, Hoover produced over two million of this model for post-war America. It sold from 1946 to 1950. Model 63 In 1953, Hoover debuted the 'deluxe' Model 63 for $116.95 ($ today). It was the first Hoover to utilize a full wrap around bumper and a completely disposable dust bag. The cleaner was styled in two-tone baby blue (base) and navy blue (everything except the base). It was an extremely popular model and sold over four million units. The machine was produced from 1953 to 1956. It was sold, in smaller numbers, in the UK, as the model 638. Again, this machine was designed by Henry Dreyfuss. Hoovermatic A long-running line of top-loading twin-tub washing machines which ran from 1948 until 1993, sold mainly in Europe, Australia and New Zealand. Hoovermatics were also sold in North America under the Washdog name. The machines used a unique washing action which made use of an impeller (known as a "Pulsator"), situated on the side of
