My first robot vacuum cleaner—there is nothing like it. The way it functions is that it first creates a map of the premises, on which you can mark the zones that do not need to be processed. After that, it is started remotely (while you are driving home) by pressing a button on the program. The acquisition has met my expectations. I did the correct thing by taking it without a docking station, as I now realize. It's easy to add water or clean the tank of dust.
