Our last cleaner died and with four pets, kids and a hubby who's a mechanic, my carpets get filthy quick! I have a tan Berber carpet that was almost black by the time I finally got this and boy was I impressed! I think it actually did better than my last one that was more expensive! The only issue I have and its a big one, because it's so low, something on the bottom is catching loops of the carpet and pulling it up so I had to stop mid way to cut pieces of carpeting that it yanked out! But other than that I am really happy. Thankfully we're moving soon so I can use it again, lol
