This is my second Shark, loved my first one, (had an unfortunate incident with it) was literally sorry to see it go, it was awesome!
So when I had to get a new one, no question about it, Shark it was!!! Dog hair is a big issue with me since I have 2-50 lb. mutts and one of them shed all year long.  Couldn't wait to get this one specifically for pets, and add the long extension hose was a big plus!!  The only thing I really miss is the light on the wand, especially when cleaning under the beds or fridge, have to use a flashlight, hard to hold the light and vacuum under things. But overall, I would recommend a Shark vacuum to anyone!!!!!
