Well ..yes ..we have a large hairy dog ! But Miele do other models . My brother bought the Allervac Sensor 5000 which is here

More expensive but he is pleased with it.
It depends what you want from a vacuum cleaner really ..we went for the cat and dog because of the dog obviously .I like my Miele because it's light ,all the tools are on board unlike that wretched Dyson where I had to cart them around in plastic bag ,and it has great suction ,gets all the dirt and gritty bits up and you get right up to corners and into places where the Dyson never dared to go !
We have stripped floorboards in the whole house no fitted carpets only rugs etc so it's ideal for me. My bro on the other hand is carpeted up to his armpits so that one is ideal for him.
