Vsevolod, please contact me at neato@eciplus.net (alias address).
I have a D7 connected that just won't do its job, vacuum starts, brush starts, but then system aborts, tries 3 times, and then red icon. Mobile app says "reboot".

Contacted Meato support, they said to send for repair, out of warranty (purchased Aug 2019).

Can you help better than iFixRobot?
