I got this machine about 6 months ago for my cats. I never write reviews but I am so impressed with this I felt it was worthy of my time. My 4 year old smeared black gel eyeliner over a 2X3 ft area of tan carpet in my bedroom. I cried myself to sleep thinking it would never come out. The next morning I decided to give it a try with my Bissel, but didn't expect much. The eyeliner came out completely! This is the best little machine I have ever bought/used. I am so glad to have it. It literally solved a Mom's worst cleaning nightmare! Awesome product.
