Eufy RoboVac 30C vs Roomba 690 - Review and Comparison

I get notifications from EIFYHOME all the time… eg eufy side brushes are stuck, drop sensors are dirty. Using iPhone EufyHome app and Eufy [BoostIQ RoboVac 30C.

But the Robot works?
No beebs from the machine?
Only the app indicates these errors?
