My husband and I are not easily impressed, but this machine did it in record time. We have two dogs and a cat... one of the dogs is approximately 14 years old and has forgotten that she's housebroken. Our hallway and office carpets were riddled with evidence of her past transgressions. When the PowerDash Pet arrived, I didn't waste any time putting it to work... and work it did! in record time, we had cleaned both the hallway and the office and expanded our range into our bedroom. We're in our mid-60s (and not in the best of shape), took our time, took breaks as we needed them for lunch and to rest our backs, and it still only took us 3-4 hours for two rooms and the hallway. The carpet looks GREAT and smells even better. You do have to fill the clean water tank and empty the dirty water tank frequently, but that makes it easier to handle. It's made in the USA and doesn't cost an arm and a leg! This machine is a keeper!
