I have this one too and I agree. It's great.
I'm very surprised how well the Shark Navigator Professional works! My mom bought it for cat litter and pet hair for her hardwood floors and it picks up everything, plus it also does well on her area rugs. What I really like about it is the ability to use it as an upright vacuum and convert it to a canister or portable hand-held as needed. Since using hers, I think I'm going to get one for myself to use in the hardwood areas and throw rugs of my house (I have a Kirby for my carpeted areas).
I think it's a good choice!
