Bests & Worsts Reviews from Amazon

I used this to clean up cat pee and it has now destroyed two pieces of furniture because the soap darkens the fabric color. At first I thought it just needed to dry, but then it dried, and two beige cushions now have dark spots. Awful. And the suction is not good anyway. I never write reviews, but feel compelled to warn future customers off of this product. I don't understand all the positive reviews.
