I have Bissel carpet cleaner. It was about two hundred at Target. I love it!!!
If there is a spill or acciedent I go grab it out of the closet and clean away. I know it is kind of expensive but I bet in the long run it work be cheaper than having people come out to do it. It really does a good job and they have a kids and pet formula. I hope this helps. Good luck with the potty training.
