Eufy 30C drop sensors dirty

#1

I have the RoboVac 30 C and I get three beeps and flashing red light which indicates drop sensors are dirty. I have cleaned the sensors, taken the front bumper off and cleaned, and also taken out the battery and unplugged it and plugged it back in. Didn’t fix it. Called Eufy but it’s out of warranty. That was their solution- replace it. Anyone fix this problem without replacement? Thanks

I am having a similar problem. Drop sensors are clean. They have worked well for several months. Now don’t work. Any solutions??
