I don't know how to return such a bulky item, but would if I could!This vacuum has terrific suction, but the problem is the brushes keep spinning even on a hard floor and spits everything back out! Plus it is cumbersome and falls over easily if you are using the too-short hose. The instructions weren't very clear in what was included for parts. It said a hand-held wand, but it took me using twice to figure out that it was actually inside the handle of the vacuum. It was also missing the furniture brush attachment and It's not as lightweight as I expected. Overall, a big disappointment because I've ben shopping around for a while and feel like I made a big mistake!
