THE SPOTBOT has been the best invention ever! I moved to a new place and my pet dog goes potty everywhere. The spotbot goes everywhere she does, and you can't even tell a dog lives here. Thank you. I only use the auto-clean. It gets used 10 times a day. It does 4 pet potties per fill. I use the pet odor solution. Thank you Thank you.Put rollers on it, eliminate the manual usage, and the dog can practically pull it herself when she goes. I want to get a second one but all the store are sold out! You are genius'. Did I say Thank You For Inventing The SPOT BOT? Thank you
