Its just gross what came out of my clean carpet. Up until now I have regretted my decision to go with frieze carpet. I love the look but it doesnt take long for it to become trampled looking and matted. And I have pets. Pet hair  friezemess. So I bit the bullet and sunk a small fortune into the Dyson. Carpet still looks awful but I at least thought it was clean! You can see for yourself what was left in that carpet. And this is what I got out AFTER I used the Dyson. After the initial shock of how nasty my carpet was, I realized this vacuum might be the best money I ever spent! I am so pleased and beyond thrilled that my new granddaughter will not be crawling around be on that filth! Im gonna go vacuum some more  Thanks Shark and thank you Wayfair!
