I’ve had my Eufy for about 2 years not and it has worked fine. Just recently it’s been incapable of finding the base station (which it previously had no problems finding)
As a test, I took a fully charge Eufy, pulled it back 6 inches and hit the HOME button on the remote. The unit started up, turns around and ran away. I stopped it, put it in manual mode, turned it back to the base unit and turned it back on. Same thing.
Just to be safe, I power cycled the base station (can’t hurt) I also cleaned the front panel of the robot in case something was blocking the IR signal. Neither helped. Not sure how to test if the IR signal is 1) not being sent or 2) not being received.
