Eufy RoboVac Error Code 12: How to Fix It

Q: How do I know if my Eufy RoboVac is charging?

When placed correctly on the dock, the LED indicator on the RoboVac will turn solid blue or white (depending on model). The dock itself usually has a solid green or blue LED when powered. In the EufyHome app, you can see the battery percentage.

Q: How long does it take to charge a Eufy RoboVac fully?

Charging time is typically 4-6 hours for a full charge. Older batteries may take longer. If the vacuum has been completely drained, it may need up to 8 hours.

Q: Why does my RoboVac keep saying low battery error?

Possible causes include a weak battery, poor connection with the dock, dirty charging contacts, or the dock being placed in an area that the vacuum cannot easily reach. Also, if the vacuum runs for too long before returning to dock, it may run out of battery.
