This is my 4th Little Green in ten years. It gets used almost every other day to clean up the carpet after the cats grace us with a hairball or other "accident". This unit replaces a SpotClean Auto Portable, which self destructed after less than a year. Very happy to get back to the larger capacity soap tank again, and the simpler design (at a lower price point too!). Hopefully this one will last longer than its predecessor.
