Most models of Dyson vacuum come in two versions: the Animal and the MultiFloor. The Animal series is designed to pick up pet hair and the extra dirt that comes with pets, and these vacuums have a tangle-free turbine attachment. A Dyson MultiFloor model is essentially the same as the Animal but without the extra attachments. So, if you have pets, go for the Animal, and if you don't, the Multi Floor will suffice.
