We have a Dyson and the thing is a godsend! We have a great dane that sheds more than everything else combined, but it is quick and easy to run the vacuum around and get it taken care of. We got the Animal model, and it doesn't have the ball, because I read several reviews of those models having suction issues. One complaint that a lot of people seem to have about Dysons is that the bristles are too stiff and cause the carpet to shed, potentially reducing the lifetime of the carpet. However this makes it wonderful for getting all of the poky dog hairs out of the carpet, which used to drive me batty.
