After wearing out our original Little Green Machine that was almost 20 years old, we replaced it with this new model. We are just as satisfied with it's performance as the last one. We have an old pup who is having potty problems and this little machine is saving my carpet. It also cleans the carpets on our cars and small area rugs. I am planning on trying it on some chairs soon. A must for any home with animals and small kiddos.
