How did I live without this? My sons dog has a pee-in-the-house problem. Spot Bot works really well, but leaves the carpet really soaking wet in the spot it was placed on. Machine instructions say to leave it and it will continue cleaning down to the carpet backing. No, it just ends up staining itself. I take an old towel folded up and place it over the we freshly cleaned spot and step on it to blot. Works really well and your not left with the circle from where the SpotBot sat.
