Our Miele cylinder is still going strong after two Dyson uprights died. I did manage to repurpose one for diy for a fair while tbh. The G-Tech air ram was quite good at first and then could not cope with the long hair and broke so Costco took that back. We got a Dyson V6 fluffy a couple of months ago. That is really handy but already replaced it once as it stopped charging. So fingers crossed it lives. Any rotary brush seems to get ravelled up with long female hair in my house. But the V6 seems fairly easy to unravel so far.
