I purchased a Bissell Pet Spot Bot. At first it did pretty well even though it left spots lighter than my carpet.
Then is started not suctioning all the soap and liquid back up. As time goes by it gets worse and worse. It leaves more and more liquid behind. It has now ruined several spots in my carpet because I cannot get the liquid out of my carpet.
That leaves a bigger stain than my pet did. Now it looks worse than the original pet boo-boos.
Don't buy this product. It is total junk and a waste of $150.00
