I have owned a spot bot, since they have came out. Over the years, they have made change to them to improve them. I have 3 dogs and they are all potty trained, but if we are gone more than 4 hours, sometimes one has an accident. We are retired so they are on a schedule and if we are gone too long past their schedule, and we don't know which dog had the accident, we don't punish them, we just grab the spot bot. it works so good, that when it's done cleaning, my carpet is cleaner that one spot than the rest of the carpet. I would love to try the dog bath accessory, but I'm leary. I have a bad back and that would be perfect. I just haven't seen enough reviews on it. If you want to send me one, I would gladly use it on my 3 dogs and write an honest review for you.
