The downsides are not very major; nonetheless, I am looking forward to the introduction of a self-cleaning station so that I do not have to deal with the inconvenience of emptying the container. Has some pros: The new type of the main brush is convenient, and it is great for everyday cleaning, operation with a timer, high autonomy, and wet cleaning. Some cons: Problems with placement if you travel to an unknown space, such as trying to recognize the former room; the quality of cleaning coverage worsens as a result of this; modifications to maps that are already known. When you are cleaning the container, make sure not to fill it all the way to the top because there is an open hole in the middle and you could perhaps spill some little debris.
