Others have commented similarly, but I just have to say that we've tried various Dysons over the years, and they always start off brilliantly. E.g., we vacuumed a nominally clean bedroom with a new Dyson upright and it was like steam-cleaning, or better, since it was dry--we pulled out a whole container's worth of dirt. But then after 6 mo to a year, they start to fall apart, with (their many internal) joints not sea…
I've had my Dyson upright for probably nearly a decade now (or at least 7-8 years that I can account for at minimum). It started off as a vacuum for a retail store I owned, and was used every single day for about an hour solid, for about 4 years, until I sold my stores... and has since been my home vacuum being used weekly. I've never had it break down, or any parts fall off, and it still works better than any other…
My mums second dyson is still going strong.
I keep hearing people claim they don't work well, I picked up my own because my friend said it worked like shit. I had a stray thread on the end of a matt and it stripped 3 rows of fibre before I got it shut off. The suction is incredible, I honestly just think people don't know how to vaccuum properly.
