The vacuum cleaner plowed for a year, I was happy. I did another maintenance: I wiped the sensors, cleaned them, and most importantly ated the software in the application. After that, the vacuum cleaner does not turn on (((I called the officials, gave the partner’s service contact, they said that apparently there was a problem with the firmware or the board after the ate, but it couldn’t help, because the manufacturer does not provide spare parts. In general, everything is fine, but after a year problems begin and fix they are not possible. Other service centers also shrug their shoulders and cannot help
