I understood them back when my parents bought a Dyson bagless vacuum back in the early 2000s (iirc). It was high tech, powerful (I still remember them showing me how much more dust and dog hair it pulled out of the carpet), and advertised no loss of suction.

Unfortunately it did lose suction over time, and was eventually replaced by an absolutely ancient Kirby vac (the kind that were sold by door to door salesmen god knows how long ago), which is built like a tank and still works perfectly well today. Probably the sort of thing I'd put in the "buy it for life" category.

I still kind of put Dyson in that early 2000s category of products - both for aesthetic and general attitude reasons. It has that energy of "it's the year 2000, so stuff is now HIGH TECH", but often times the older, less flashy stuff is still better.
