I was really looking forward to using the Bissel stain remover and so far am not disappointed at all. The reviews were scattered with positive and not so positive things about the operation of the machine, so I was skeptical about the success of the machine. My puppy has a lot of accidents on the carpet and I find the machine super easy to carry and use. It works like a dream, taking out the stain, even older stains that might need a few applications really work well. Really happy I got it.
