My very first automated vacuum cleaner, and there is simply no competition. The way that it operates is similar to this: in the very beginning, it creates a map of the premises, and then on this map, you can mark the areas that do not need to be processed. After there, it may be started remotely by pressing a single button within the application (while you are still on the road to your house). The transaction was completed to my complete satisfaction. Now that I have it in my possession, I see that my decision to purchase it without a docking station was the correct one. Adding water to the tank or removing dust from it is not an issue at all.
