NOTE: I have reached out to Anker support for this issue, but unfortunately none of their troubleshooting tips have helped, and I am out of warranty as of April (the issue started in June; go figure).
Hilda, my Eufy Robovac 11, continues to function and clean perfectly, but she has developed an extremely annoying habit. After each cleaning cycle, she returns to her charging station like normal. After charging normally for 3-4 hours, she gets angry. Her LED light will go from "breathing" blue to solid red, followed by five repetitions of four beeps. The light then goes back from red to blue for ~5 minutes, after which the process repeats. The whole process happens at least four times in a row, after which she quiets down until the next time I need the apartment vacuumed. It's incredibly annoying and never fails to startle me and my poor cat, who already hated Hilda enough as it is.
I have tried:
-Charging directly through the cord
-Cleaning charging connections
-Removing and cleaning yellow spinning brush, including taking the black connectors off of each side and cleaning its interior (as suggested in another thread with a similar issue)
-Running Hilda with all brushes removed
I have seen this issue pop up on the forum, but Anker is usually quick to suggest a private email exchange with support. Hilda is just about ready to bite the dust. Does ANYONE have a solution?
