I bought this vacuum close to two months ago. I loved it at first it was everything I could have wanted after the third vacuum I noticed that the suction on it wasnt what it was when I first got it. I have 3 dogs, they really don’t chew much if at all, and 2 children. I have unclogged the hose (which isn’t easy), checked the filter, checked in the spot behind the roller and still can’t figure out why it’s not working. i love this vacuum and just want it to start working again.
