We bought this when we got a puppy and our daughter started potty training. It was great with cleaning up messes from both. HOWEVER, after not using it for a few months, I pulled it out to steam our couch, and it no longer worked-it wouldn't spray. I followed directions posted in a review to clean out the tubes, but that didn't work (and I broke off a piece of plastic taking off a tube because the tube had glued itself to the plastic). At any rate, it seems the heat box was no longer working and was overheating, and the heat light was on no matter what. When I put it back together, it still wouldn't spray, and then I could smell the machine overheating. I chucked it. Now I'm looking for a larger steam vac that will do whole carpets and upholstery.
