Great vacuum for my constant shedding lab.  I was looking for a cordless for quick vacuum jobs and this does a great job.  I love the extra large tank because I don't have to empty is 3 times like my last Dyson.  I also like that you don't have to hold in the handle.  It has a push button start.  I also love the light in the head except for it will make you crazy when you see the dust you didn't know about.
I give 4 starts because I feel it's a bit heavy.
