eufy Robot Vacuum Error Codes — Complete List

eufy's RoboVac X8, LR20, LR30 and L35 series speak their errors aloud: plain numbers for something stuck or trapped, and S-codes for a module that needs attention, such as the battery. eufy lists a quick solution beside every alert, and these guides stick to that list.

• Error 1 eufy RoboVac Error 1 means the front bumper is stuck, usually on dust or debris trapped behind it.
• Error 2 eufy RoboVac Error 2 means a wheel is stuck or trapped and the robot needs freeing and its wheel checking.
• Error 4 eufy RoboVac Error 4 means the rolling brush is stuck and has to be removed and cleaned.
• Error S1 (S1) eufy RoboVac Error S1 is a battery error, and eufy's fix is to re-establish a clean charging connection.

Older and simpler RoboVac models signal faults with beeps or flashing lights instead of spoken numbers. If yours does, use eufy's article for that model family.
