I have had this vacuum for almost 2 years (we got it as a wedding gift) and I can say this vacuum does NOT vacuum well at all. It will act like it is sucking stuff up then spit it all back out. It will help pick up some of the dog hair and that is about it, but if it's clumped up it spits it's out too. I was so excited to receive my first Dyson vacuum but it turned out so disappointing. 

I will never buy a Dyson after using this one.
