I have had small Shark vac and several of their hand vacs. Like them very much, only issue is getting replacement filters which have to be ordered through the company. My neighbor had a Dyson to deal with multiple animals and was not satisfied with it. Replaced with Miele. Personally I prefer a model with a bag as the animal hair flies everywhere when emptying canister. I now have a Miele upright and it's great. Still use my old Shark in the basement.
