Top model with laser and video eye. Like the third series, the latest in technology. You need to fight with the Application in order to figure it out, to connect it. The first connection occurs only when geolocation is enabled, sort of. I don’t really remember, because I installed everything almost a month ago. But YouTube has detailed instructions on how to simply Russify and connect to the application. I spent almost a week to choose a robot vacuum cleaner. Initially, I didn’t want to spend more than 10k, but then I realized from the functionality that there are useless robots, but there are very fast and intelligent ones. It has powerful suction and a large battery. Enough to go through the whole apartment 2 times.
