Not the smartest RoboWack. Not the dumbest robot. In the house, however, it moves well and the suction power is good. High quality mop. Works with Google Home and Alexa. I'm just saying: Hey Google, start the cleaning and the vacuum cleaner robot. Picks up dust and dirt. Of course. Nothing is as big as a normal vacuum cleaner. Overall, it saves you a lot of time and effort. The only downside is that when mopping, it will mop up your carpet unless you block or lift it. And sometimes it can get stuck somewhere in your house, but that's rare.
