I bought this robot because I liked my shark duo. What a waste. Issues since 2 months old. It randomly starts during day on its own, can't find the dock when it's sitting about 2 feet from it, says max full when just emptied....I could go on. Just wasted about an hour of my time trying to chat with support. I was literally told I justneed to put out on the charger. Then push clean. ARE YOU KIDDING us in aware how it works. You are not aware that the robot itself is not working
