Roborock Error Codes 1 to 28 and How to Fix Them

Roborock error codes run from 1 to 28, and each points to a part: Error 1 is the LiDAR turret, 2 the bumper, 5 the main brush, 8 a trapped robot, 9 the dustbin, and 13 charging. Most clear once you clean or free the part and restart. Roborock suggests a reset for some electronic errors, and contacting support if a code keeps coming back.

Last reviewed: October 2026. Codes and fixes come from Roborock’s manuals and support pages. Newer models may describe the problem in the app instead of showing a number.

Roborock error codes

Error 1: LiDAR turret or laser blocked. Check that the turret on top spins. If it does not, turn it gently by hand, clear any obstruction, and restart.
Error 2: bumper stuck. Clean it and tap it lightly to release it.
Error 3: wheels suspended. Move the robot to a flat spot and restart.
Error 4: cliff sensor error. Wipe the cliff sensors and move the robot away from drops. Roborock also says to keep it off dark or shag carpet.
Error 5: main brush jammed. Remove anything tangled in the brush, including its ends and bearings.
Error 6: side brush jammed. Remove the side brush and clean it.
Error 7: wheels jammed. Turn the wheels by hand to find what is stuck, free them, and restart.
Error 8: robot trapped. Clear obstacles around it and check that the wheels turn. Roborock also suggests removing the water tank if one is fitted.
Error 9: no dustbin. Install the dustbin and filter. If the error stays, check for the magnet on the side of the filter. If there is none, replace the filter.
Error 10: filter blocked or wet. Clean the filter, let it dry completely, and refit it.
Error 12: low battery. Recharge and try again.
Error 13: charging error. Clean the charging contacts on the robot and dock, check the dock’s power, and reseat the robot on the dock.
Error 14: battery error. Roborock’s manuals list no owner fix, so contact Roborock support.
Error 15: wall sensor dirty. Clean the wall sensor.
Error 16: robot tilted. Move it to level floor and restart.
Error 17: side brush error. Reset the robot.
Error 18: fan error. Reset the robot. Roborock also suggests tapping the side of the robot a few times to shake debris out of the fan.
Error 21: vertical bumper pressed. Move the robot and try again.
Error 22: dock locator error. Clean the sensor and try again.
Error 23: could not return to the dock. Clean the dock’s signal area and try again.
Error 27: VibraRise mopping system stuck. Check for obstructions.
Error 28: robot on carpet. Move it onto hard floor and try again.

Roborock’s manuals we read do not list Errors 11, 19, 20, or 24 to 26.

Messages without a number

Filter blocked or wet: clean and dry the filter.
No-go zone or virtual wall detected: move the robot out of the area.
Cannot cross carpet: move the robot to the other side and restart.

When the error means a repair

If a code returns after cleaning, the fix may be a part such as a brush, filter, or battery, or a repair by Roborock. Roborock robots carry a one-year warranty in the US, and Roborock’s warranty treats batteries as consumable parts. See Roborock repair and warranty and repair or replace a robot vacuum.

Frequently asked questions

What does Roborock Error 1 mean?

The LiDAR turret on top of the robot is blocked or not spinning. Check that it turns freely, clear any obstruction, and restart.

What does Roborock Error 9 mean?

The robot does not detect the dustbin. Reinstall the bin and filter. If that does not work, check that the filter has its magnet.

How do I reset a Roborock?

Roborock’s support page describes a Reset button under the top cover. A reset restores factory settings, so you will need to set up Wi-Fi and schedules again.
