He worked perfectly at the dacha - he built a map and rode around the first floor, washed and vacuumed. The app was stable enough. They took it to the city - they rebuilt the map (I didn’t create a new one, you can’t do it in the application with your hands), glitches went. Now the map is unfolding, then it is lost. Disappointment. Data is loading slowly, you can fall asleep It does not allow you to start cleaning a specific room again without completely exiting the application and restarting it, and this does not always work the first time But if it starts, it cleans up as it should Total - troyban, at such a cost - it makes no sense to take
