White Berber
I have white berber with some neutral colored specks through out in our den and it has taken a beating over the past 10 or so years since we have had it. I do shampoo it every so often with my Kirby but it doesnt do the greatest job. At the begining of June I became fed up with the numerous stains that had appeared on the carpet and was contemplating buying a Steam Vac. As mentioned above Consumer Reports recently rated several units and commercial carpet cleaning companies. I was thinking about the Hoover All Terrain but after all the reviews I have read, CR, ePinions, here on vacuumland, and on the web, I decided to go with Stanley Steamer. They did an fabulous job on the rug, along with our spare bedroom, an area rug, and two of the cats perches (which are an off white color). I booked the entire thing online the day before and never even had to pick up the phone. While there is still one small stain that they could not get out, the rug looks wonderful and around $230 it was money well spent.
My concerns with the Hoover was its durability, cleaning power, and most of all how much water it removed from the carpeting. My biggest fear was that it would not remove enough water from the carpet, leaving it too wet and taking forever to dry. This can also cause mold to grow in certain climates or cause the rug to smell. Several years ago we had a company that my mom uses in her office clean our rugs, they specialize in cleaning carpet and upolstery in homes that have had fire damage. While they were more costly than Stanley Steamer, they too did a wonderful job and seemed to be very knowledgable in removing difficult stains.
Dan, I noticed that you said you use your Kirby after the steam vac. From what I have read here in the past, most people who own a Steam Vac and Kirby, use the Kirby first and then the steam vac. That way you can scrub the carpets and then remove all the soapy residue that the Kirby leaves behind, decreasing the rate of the carpet re-soiling.
