I had a part-time job as cleaner when I was younger. We used Henry hoovers. They were used and sometimes abused 5 days a week... during the almost 3 years I was there, I think I only saw hoses and the floor head breaking.

So after going through a few hoovers at home from different brands, I bought a Henry for £100 3 years ago. The nose/hose detached after a few months. Not ideal, but I've fixed that in minutes with a bit of superglue. No other issues since then, no indications that it's about to fail.

I don't know if quality is still exactly the same as before, and they're certainly a bit heavier and noisier than some alternatives, but if you want something that lasts, get a Henry, not a Dyson.
