I am not one that usually goes around writing product reviews or telling people how to clean their house (I am by no means an expert!) But I just wanted to put this here because I have a Bissell Little Green. I also have a dog and a cat who both occasionally get on their high horse and forget where to do their business. The cat also has issues with hair balls. This little baby, the Bissell Little Green does the job. Period. For pet potty accidents, I put a mixture of hydrogen peroxide, water, and vinegar in the soap chamber. Clean, clean, clean with the Bissell Green Little Green. Then I sprinkle baking soda and let sit for 15 minutes or so. Vacuum up. Odors and stains gone.
