I don't own one, but I have heard from one source that they are not "all that", they are overpriced.
And yet, another source has said that it is great (this would be the model for pet hair).
So, I don't know, personally.
My husband bought us a Kirby a few months back, and he traded in my Hoover for it

Needless to say,
he is the one that uses the

Kirby.
I had my own cleaning business cleaning houses, and I got to sample just about every vacuum on the market, which is why I didn't want to even fool with a Kirby (it does work very good, but it is a complete PITA to use) and I prefer the Hoover over all of them. This was before the Dyson, though.
