I bought the shark carpet xpert with stain striker a week ago after watching the infomercial! Mark (the founder) was NOT lying! It does anything he said and smell wonderful!! I cleaned several spots from my dog (number2) that had been in my carpet for over a month. We rented a commercial carpet cleaner and also used a spot carpet cleaner that we already own and the spots were still there. Barely noticeable but still there. I would recommend a million times! If you have carpet and kids and/or pets you NEED this machine!
