These cleaners are a perfect example of why Hoover needed gimmicks to keep selling new stock; there was virtually no obsolescence built into them, as they were rock-solid to start with, and could easily (not to mention cheaply) be repaired. When it came to making products with a limited lifespan, Hoover did it so very badly. Either the products were built like tanks, or they fell to pieces within a few short years, depending of course on what model one had. Electrolux on the other hand knew just how to do it.
