The robot is definitely worth the money, all the troubles are due to the application, but there are not so many of them and they are slowly being corrected. Two important observations: 1. If the robot has lost connection with the application, just log out of the account and log in again 2. Before filling the tank for the first time, do the following. Pour water))), blow into the filler hole of the tank, and at that time press the valve with your finger, the water went, remove the finger, wipe it and install it (I personally avoided problems with the water supply, there were no more problems) All the declared functions perform 100% and with high quality, it is controlled via wifi and 4g without problems (if that is the first item)). It is better to run the first 3-4 cleanings throughout the apartment, and only then, as you wish, edit the map, select zones, etc.
