Query: Very Impressive Machine

While vacationing in our camper, our dog got into the garbage, which contained coffee grounds, and strewed it all over our Berber carpeting. We borrowed our friends Dirt Devil carpet shampooer and the carpet cleaned up like new. As soon as we got back home I ordered one exactly like hers. At home, I have pile carpeting throughout, including the kitchen. Over time, I have owned three other shampooers and have had my carpet professionally cleaned. This unit outdid them all!I think one of the major reasons it works so well is that you can go from shampooing to rinsing and from brushing to just vacuuming by just pushing buttons. Rinsing gets rid of any shampoo residue and just vacuuming extracts so much of the water the carpet dries in no time.
