1. Verify the Mop Pad and Its Installation
- Turn off the robot and gently remove the mop pad from the bottom.
- Check the mop pad for dirt, debris, or wear. If dirty, wash it in warm water and let it dry completely.
- Ensure the mop pad is properly aligned and securely attached to the mop assembly. An improperly fitted pad can prevent mopping from activating.
- Reattach the clean, dry mop pad and power on the robot to test if mopping resumes.

2. Confirm Water Tank & Mopping Settings
Check that the water tank is correctly installed and filled with clean water. If it’s empty or improperly seated, the robot won’t mop.
- Remove the water tank, refill it to the indicated level, and ensure it’s securely reinstalled.
- Open the Roborock app or control panel and verify that the mopping feature is enabled for the cleaning schedule.
- Adjust water flow intensity if your model allows, to ensure enough water is being delivered for mopping.
3. Inspect for Blockages and Obstacles
Blockages can prevent water from reaching the mop or interfere with the mopping process. Check the water outlet, tubes, and water delivery system for clogs.
- Remove the water outlet or delivery tube, if accessible, and clear any debris or mineral buildup.
- Ensure the water delivery area beneath the robot is free of hair, dust, or obstructions.
- Make sure the cleaning path is clear and the robot isn’t stuck or complicated by obstacles that prevent mopping.
4. Update Firmware and Recalibrate if Necessary
Firmware updates often include bug fixes that improve mopping functionality. Check for updates via the Roborock app and install any available updates.
- Go to the app and select your device, then navigate to firmware updates.
- If the problem persists, try resetting the robot to factory settings and recalibrating its sensors and mopping system according to the user manual.
5. Additional Troubleshooting Tips
If your Roborock still isn’t mopping after the above steps, consider these tips:
- Test the water flow manually, if possible, to check if water is being delivered.
- Ensure the mopping system is turned on in the app and that there are no restrictions in the cleaning schedule.
- For persistent issues, contact Roborock customer support or consult the user manual for model-specific troubleshooting.
