Frequently Asked Questions

What does error code 8 mean on a Eufy RoboVac?
Error code 8 means the left bumper is stuck. The vacuum's sensors detect that the bumper cannot move freely, so it stops to avoid damage.
How do I clean the bumper on my Eufy RoboVac?
Turn off the vacuum, then use a soft brush or compressed air to remove debris from the bumper gap. Wipe with a damp cloth if needed, then test the bumper movement.
Can I reset my Eufy RoboVac to clear error 8?
Yes, you can try a factory reset. Locate the Reset button (often a pinhole) and press it with a paper clip for 10 seconds. This will clear the error and restore default settings.
Do I need to replace the bumper if error 8 persists?
Not necessarily. If cleaning doesn't work, the bumper may be physically damaged or the internal spring may be broken. A replacement bumper assembly is available from Eufy.
How long does it take to fix error code 8?
Most cleaning fixes take 10 to 15 minutes. If you need to replace the bumper, it may take 20-30 minutes.
