My mom purchased the Little Green quite a few years ago and it continues to work just as great as it did the first day she purchased it! I love the compact size, the way the cord can be wrapped and secured, and the ease of emptying the waste container. It is definitely a worthwhile investment for spot cleaning since it is portable, light-weight, but extremely effective! We used it for our senior dog who had quite a few accidents in the house in his later years and it was perfect because we could bring it out quickly, right away and it thoroughly cleaned the mess. I promise you will love this machine!
