Query: Waste of money

It overheats every few minutes. Total waste of money. You cannot even vacuum a couch in one try. It is marketed for picking up pet hair but you can go over the same spot on a couch 10 times and it still leaves it behind. If you want it for that purpose you would be better off buying a $5 Pledge pet hair sweeper.I am writing this review while waiting for my vacuum to cool so I can finish the couch. This thing is going in our next yard sale and we are going to look for something else. Save your money folks.
