I've had a Dyson DC40 for 8 years now, I haven't had any problems with it. I would say it gets more than average usage. The only two things that were "broken" on it were the hose and this little wire harness (loom). I've noticed that the brush head spins intermittently, I checked and cleaned it thoroughly, but sometimes it still wouldn't spin. I decided to order this and the brush head unit. This item arrived first. This was a little tricky as there is no YouTube video specific to this modelβ¦
