In general, I am satisfied with the purchase. The launch of cleaning in a selected area is the feature that offers the greatest benefit. For example, if something wakes up in the kitchen, you can send it to clean only this patch, rather than having to force it to clean everywhere. The application performs adequately despite the fact that it occasionally experiences bugs. For instance, it does not save some cleanings to the archive; however, this is not a crucial issue. I had to purchase another signal repeater because there were some areas in the house, just a few walls away from the router, where there was no wifi and the vacuum cleaner got lost and could not find its way back to the base. If you want the robot to do its job properly, you need wifi throughout the entire house. If you need a vacuum cleaner that can clean not only the entire room, but also a certain kind of specialized region, for instance, if you can only clean it in the hallway at the threshold, where the dirt from the shoes was poured, then this is the model that you need. You don't need to bother with ribbons or anything else, and this is also what you need. If you have a lot of places where the robot should not go, for example, scattered children's toys in some corner of the room, then the virtual walls in the application are a great solution. If you have a lot of places where the robot should not go, for example, scattered children's toys in some corner of the room. If you are a bachelor and you don't have anything extra lying around, then this is an opportunity for you to get something more straightforward and put it through its paces before going to work.
