I've been reviewing vacuum reviews for quite a while as our new home was being built. The reviews all lead me to the purchase of this Shark model. With 2 large dogs, one being a yellow lab, but we lovingly refer to him as a "yellow shedder", and hardwood floors as well as carpet this has proven to be just what we need, even though we brush the dogs very frequently. This vacuum sucks up the dog hair instead of blowing it around. The lightweight canister makes vacuuming the stairs a breeze. The canister does not require a bag, I love that cost savings! Also, it can be emptied right into your compost bin with ease. Yes, dog hair can be composted. Wayfair had the lowest price around.
