I can't recommend anything, because I don't really have animals, but I can tell you that I have a Dyson, and I can't wait for the thing to die. We had once before, and you know the saying Fool me once shame on you, fool me twice shame on me, well lets just say that I have been shamed.
I would NEVER buy another Dyson, they are horrible vacuum cleaners.
I love my animal too. As long as you do basic maintenance (clean filters etc) it will run forever and pick up just about every thing I throw at itI must be the only one who loves the Dyson. I've had the Animal Dyson for 11 years and it is still going strong. We had a Kirby salesguy demo his stuff a couple of weeks ago. We went over it with the Dyson afterwards and was amazed what the Dyson still picked up. It was a great investment as I averaged a new vacuum every couple of years. I won't hesitate to invest in another one if I ever have to.
