You can use the quick navigation tab to go to a specific Roborock error code.
Roborock Error Code Troubleshooting
If Roborock is experiencing an error, the power indicator will flash red quickly and you will hear a voice alert. You can use the Roborock error code troubleshooting below to identify the problem and find the solution.
The troubleshooting guide below applies to all Roborock models. Newer Roborock models will have more error code possibilities than older versions because they employ better technology.
Error 1: LDS unit is jammed
Error 1 means the Roborock’s laser distance sensor (LDS) is jammed.
If your Roborock is not moving, then the laser distance sensor (LDS) is jammed, causing it to not spin freely. Turn on Roborock and watch to make sure the laser unit is spinning as it should.
If the laser unit is not spinning, rotate the laser head manually to check that it turns freely. Remove any items blocking the laser unit, wipe the sensors, then move the robot to a new location and restart.
Error 2: Bumper is stuck
Error 2 means the Roborock’s bumper is stuck. Clean and lightly tap the bumper. Tap the bumper repeatedly to dislodge any jammed items. If nothing falls out, move the Roborock to a new location and restart.
A stuck bumper is often the culprit of a robot vacuum going around in circles.
Error 3: Wheel is suspended
Error 3 means that one of the Roborock’s wheels (or both) are suspended. Inspect the wheels and remove any debris or items that may get stuck in the wheel wells. Move the Roborock to a new location and restart it.
Error 4: Cliff sensor error
Error 4 means the Roborock’s cliff sensors are experiencing an error.
Chances are, the cliff sensors are very dirty. Wipe the cliff sensors, move the Roborock away from raised edges, and restart. Make sure the Roborock is not on the dark or shag carpet.
Error 5: Main brush is tangled up
Error 5 means the Roborock’s main brush is tangled up.
Make sure there is nothing tangling up the main brush, including inside the two brush slots and at either end of the brush, then run the Roborock with carpet mode enabled and see if the problem has been resolved.
Error 6: Side brush is tangled up
Error 6 means the Roborock’s side brush is tangled up. It will likely stop spinning.
A build up of dust, debris, and hair can wound up beneath the side brush. Unscrew the side brush from the Roborock and clear up any debris on the housing. If the side brush is twisted and damaged, replace it.
Error 7: Main wheels may be jammed
Error 7 means the Roborock’s main wheels may be jammed.
Press and spin the wheels manually to check if they are stuck. If they are stuck, try to free them. Look for anything stuck in the main wheels, then move the Roborock to a new location and restart.
Error 8: Roborock is trapped or stuck
Error 8 means Roborock is trapped or stuck.
It is possible that Roborock becomes trapped and stuck between other objects. Please provide enough space around Roborock's path. Make sure there are no obstacles and clear objects around the Roborock.
If your Roborock keeps getting stuck for no reason (no obstacles around it), then make sure the robot’s firmware has been updated to the latest version. Nine times out of ten, there is a software issue.
You can also try pressing and spinning the Roborock’s wheels manually to check if they are stuck. If they are, try to free them up. If the water tank is installed, remove it and try again.
Error 9: Dustbin and filter not detected
Error 9 means the Roborock does not detect the dustbin and filter.
Reinstall the dustbin and filter and check they are correctly installed. If the problem persists, try replacing the filter. Look for the magnet on the side of the filter. If you do not find a magnet, replace the filter and try again.
Error 10: Filter is not completely dry
Error 10 means the Roborock’s filter is not completely dry.
Make sure that the filter is dry. Dry the filter for at least 24 hours. The filter may also be blocked and require cleaning. Clean the filter, dry it thoroughly and place it back in the Roborock then try again.
Error 11: High-intensity magnetic field detected
Error 11 means Roborock is too close to magnetic tape (virtual wall) and cannot start. If a strong magnetic field is detected by the Roborock, move it to a different location and restart it.
Error 12: Low battery
Error 12 means the Roborock’s battery is too low to start a cleaning job. Recharge it before use.
Error 13: Charging error
Error 13 means the Roborock is experiencing a charging error.
Make sure the charging contacts on the Roborock makes a clean connection with the charging contacts on the charging dock. Use a dry cloth to clean the charging contacts on the Roborock and on the charging dock. Lastly, make sure the charging contacts have not been corroded.
Error 14: Battery error
Error 14 means Roborock is experiencing a battery error. The Roborock’s battery temperature is either too high or too low. Please wait until the Roborock’s battery temperature returns to normal.
Error 15: Dirty wall sensor
Error 15 means the Roborock’s wall sensor is very dirty.
A huge amount of dust can settle on the wall sensor, which is a sensor for determining the distance between Roborock and a wall. Carefully wipe the wall sensor then restart Roborock.
Error 16: Roborock is tilted
Error 16 means Roborock is tilted. Roborock cannot work when it is placed on an uneven surface. Please move Roborock to a flat, even surface then restart the robot.
Error 17: Side brush error
Error 17 means Roborock is experiencing a side brush error.
If this is the case, there is nothing you can do but perform a system reset.
Error 18: Fan error
Error 18 means Roborock is experiencing a fan error.
If this is the case, there is nothing you can do but perform a system reset.
Error 21: Vertical bumper pressed
Error 21 means the Roborock’s is pressed. The vertical bumper (also known as the laser rangefinder) is pressed or its work is interfered with by foreign objects. Move Roborock to a new location.
Error 22: Recharge sensor is blocked by dust
Error 22 means the Roborock’s recharge sensor is blocked by dust. Dust may settle on the recharge sensors, which interferes with Roborock’s normal operation. Wipe the recharge sensor.
Error 23: Charging dock is jammed
Error 23 means the Roborock’s charging dock is jammed. Clean the charging dock locator beacon. If foreign objects fall on it, remove them from the charging dock and then try again.
Error 24: Virtual no-go zone or wall detected
Error 24 means Roborock detects a virtual no-go zone or a wall. To solve error 24, move the Roborock away from the virtual no-go zone or barrier. Then, restart Roborock in a new location.
Error 26: Wall sensor is dirty
Error 26 means the Roborock’s wall sensor is very dirty.
A huge amount of dust can settle on the wall sensor, which is a sensor for determining the distance between Roborock and a wall. Carefully wipe the wall sensor then restart Roborock.
Error 27: VibraRise system is jammed
Error 27 means the Roborock’s VibraRise system is jammed.
Check for obstructions and clear them.
Error 28: Roborock is on carpet
Error 28 means the Roborock is on carpet.
Move Roborock to a new location (not on carpet) and try again.
