I just got my t7s plus (sweep) yesterday from China and the Narwal J1 (mop) and I've gotta say this T7S+.
I've been trying to get it to map my house but it can't.
Customer service is horrible in troubleshooting and can't seem to provide a solution. This is such a stark contrast in experience with the Narwal J1 which ran smoothly and had great CS.
Anyone else's T7S+ behaving like this too?
