First introduced in 1910, after several years of research and development, the vacuum product line would become one of their broadest with exposure to residential, commercial and industrial markets. During the first few years, a joint venture produced an identical line of portables under the Western-Electric label.
The portable vacuums were composed of a light aluminum fan and case, connected to a dust separator. The fan was driven by a direct-connected bi-polar type motor. Westinghouse shut the line down in 1945.
This model replaced the earlier versions No.0 and 1.
