Like I said, the Oreck cleaners may have evolved over time with redesigned hoods and larger motors, but the original Oreck as pictured above was a direct copy of the McDonald Electric. The ME was not in itself a popular seller and David Oreck knew that, hence he very cleverly aimed the early models exclusively at the commercial floorcare market where this type of cleaner would excel, before launching into the domestic market.
Numatic in the UK have done a similar thing, although I don't think that was ever intentional as Oreck and has happened over a much longer period of time.
