Okay, I know this thing is expensive, but I've had my Miele for 20 years and it still works perfectly. I expect unless I have some crazy need to buy a new vacuum just because that I'll still have it 20 years from now. My BFF has one too and she's had hers maybe a year longer than I've had mine and she vacuums way more often than I do. Hers is also in perfect shape. I mean, cosmetically, the canister isn't pristine, but the thing works, which is what counts. And, yeah, one has to cut the long hair out of the rollers. I don't know that there's any vacuum that's long-hair friendly!
How long are you talking? I've never had to cut hair out of any of my Shark vacuum rollers. The hair goes straight into the dust canister and spins around and around and when I dump it out, it's one big ball of hair. My hair is about 12 inches long at its longest.
