I'm returning this vacuum. After over an hour spent trying to troubleshoot the issue, I have only been able to get the vacuum to function with the hose attachments. When I try to reconnect the brush head, no power. I even tried replacing the belt for the brush head, which was much tighter...but still, nothing. Either (a) this was refurbished without checking functionality as an upright or (b) it works as an upright but I'm just connecting things correctly. Even if the latter is the case, I'm a pretty smart person and if I can't intuitively get this going, it's not going to work long term for my needs.
