We bought it purely as a vacuum cleaner, we do not use the wet cleaning function. This is our third robot (the first was a simple Midea without navigation, which ran out of battery after 3 years, then 2 weeks later it was iRobot i3, which had a firmware glitch and went back to the store) The application was better with iRobot, it is less convenient to divide into rooms and the application has more functions that I have not figured out yet It builds maps better than iRobot and can correct them after several cleanings Powerful. After parsing the Christmas tree, he launched it for cleaning in the house and found a whole dryer in the container, which he could suck. I did not bring a full container after cleaning 65 meters of the floor, taking into account 2 carpets and a rug in the hallway. He, it seems, because of his power, also presses the dust After cleaning 65 meters of the floor in a 100-meter apartment, which lasts about 1 hour, there is still about half the battery charge
