I recently received the Shark Carpet Xpert HairPro Pet vacuum, and it has completely transformed mine and my wife's cleaning routine! As a pet owner of 3 cats and 2 teenagers, we were constantly vacuuming pet hair out of carpets and furniture. More importantly, one of my cats insists on marking her territory even after 12 years of ownership, as well as the spills made by two teenagers and this has made cleanup so much easier. 
This unit tackles any stain with ease and leaves the carpets feeling new and the house smelling fabulous! It's lightweight and easy to maneuver, which makes our stairs a breeze to navigate up and down. It is very quiet, and the cats seem to be less intimidated by it. 
If you are looking good for a new  cleaner to handle any task, the Shark Carpet Xpert HairPro Pet is the go-to unit!
