If you have pets, you WILL want the one for animals. Trust those of us that have it. lol
I should vacuum my carpet for you...it's just an area rug and show you what comes up out of it. Mind you...it sits in front of the slider so it does get the dust from outside, but the cats just gravitate to it because of the cool air that will blow in on them. I vacuum it once a week and am always amazed at what comes up.
