We have one of their stick vacuums although I'm not sure it is the exact same number. I'm thinking ours is a 44. Dyson seems to have several vacs that look alike but different numbers. Whatever our model number is, it works great. We use it primarily in house between major vacuuming with a corded Dyson canister vacuum (not sure of number on it either). The only negative is if you have a dog (assuming you do since looking at the Animal) that has long hair, it will wrap up on the beater bar brush roller thingie. The brush is easy to remove and clean though using just a quarter or side of a small key. I usually use our MH cargo door key.
