Query: Sprayer broke after a year of light use!!

My sister and I each purchased this Bissell model because we both own dogs and there are a couple of carpeted rooms in our homes. I had researched the Bissell Proheat and the reviews all said the sprayer mechanism melted and quit working and they had recommended the little green without the proheat feature. Well, after a few months my sister's machine stoped sucking up the water and after a year the sprayer on mine completely stopped spraying. I have switched over now to the Bissell Spotbot for Pets and so far so good. It's got the handheld manual hose feature and the hands free smart clean which I LOVE because there is no scrubbing involved. I recommend it. As for the Little Green Machine and the Pro Heat models. DON'T WASTE YOUR MONEY or TIME!!! We had to just pitch them both in the end because it would have cost more to fix them then to replace them completely. :(
