Canisters made by Eureka(back then anyway)
The "magic carpet" upright design dates from the late 40's and was IMHO years ahead of its time, and very different from anything on the market at the time. Twin fans, one on each side of the motor pulling air from the center. Today the Hoover Windtunnel V2(Savvy) uses the same principle.
That upright was a LOUSY vacuum though, its biggest design flaw was a floating brush that could get "hung up" in the nozzle and never contact the carpet. The design was revised in 1961 to the larger square base, and a much better cleaner was born.
Singer private labeled these cleaners for Sears, Lewyt(Canada), Sunbeam, and Westinghouse.
Very collectible machines today in any form.
