Conclusions: After few months of using it in my experience it's absolute nightmare. Works properly 4 times out of 10. It gets confused sometimes where it is and then resets map. Then need to do mapping and zones again. Also the zones move a little bit so need to readjust the time to time. And it is having problems with phantom objects, doing weird circles even though there are no obstacles. I can't lift it to bathroom because it will reset the map even though on the map it shows right position even when it's moving. The water tank is cracked in 2 months but it hasn't been dropped or otherwise abused. And now the app says that the V10 is offline for some time. And it's not the first time it's doing it. Last time i dried to reset it, but i couldn't get it to work with android, it just wouldn't connect. Then dried with IOS where it connected perfectly. Biggest problem seems to be the app it uses. I strongly don't recommend this robot vacuum.
