I recently rescued a cat and now have two cats and a dog.
The pet hair was everywhere until I bought The Shark Pet Lift-Away Upright Vacuum.
This vacuum is much better in lifting pet hair from my furniture, floors, and even my cat tree than any of the other vacuums that I have owned  in the past.
It is wonderful for lifting crumbs and dirt from my tile floors and in between the tiles as well.
It is super easy to use and able to get into hard to reach places for added cleanup.
