The Shark® Wandvac® Cordless Self-Empty System + HEPA is a really good vacuum that does take up much space. This vacuum is great for picking up hair, human and cats. The self empty doesn’t always get all the hair, so you may need to manually remove it, but otherwise works great. I love the fact that you can easily get to all the filters and that they are able to be cleaned. The detachable hand wand works great for furniture and louvered doors. I would definitely recommend this vacuum to people with pets.
