[Citation needed] Do you have links to these independent tests you cite? A cyclone is a long established method of dust removal industrially, and an efficient method of doing so. Compared to a typical Hoover at the time they were introduced they are orders of magnitude better and more reliable. Since then Hoover and all the other manufacturers have basically copied, as far as they are able, everything Dyson does. Hardly indicative of a terrible product. They can lack longevity due to use of plastics that tend to age harden over a decade, but that's about all I can fault them for, aside from moving production to Malaysia - but that's hardly unique in manfacturing. Some of their other products have been less successful - the now discontinued washing machine was another transformative product miles ahead of alternatives. Sadly they couldn't make them profitably. The fan heater is much harder to like being 10x the cost of alternatives but not 10x better at heating a room. Dyson cleaners frequently get Consumer's Association (UK independent home appliance tests) Best Buy. They are always towards the top as far as performance goes.
