My daughter got one of these and convinced me to get one too.  I love it.  I can zip around and it sweeps the dog and cat hair right up and the cat litter is all sucked away.  What I like the most is now when I sweep with this, I am getting the dirt and the dust.  When I broom sweep, I am just swishing the dirt, but the dust gets circulated in the air.  I already see that the dust on my furniture is less.  Yay.  Thank you.  I would definitely recommend this to others, and I already have.
