1. Check and Clean the Mop Pad and Water Tank
- Remove the mop pad from the robot and inspect it for dirt, hair, or damage. Wash it with warm water and mild detergent if dirty, then let it dry completely before reinstalling.
- Ensure the microfiber mop cloth is properly attached and fully adheres to the mop base. Replace it if worn out or damaged.
- Open the water tank and check for blockages or leaks. Fill it with clean water if empty and make sure the water inlet is clear.
- Confirm the water level is sufficient for your cleaning session; low water can cause ineffective mopping.

2. Verify Sensors and Obstacle Avoidance
Dirty or obstructed sensors can prevent the robot from mopping correctly. Use a soft, dry cloth to gently clean all sensor areas, including the bottom, front, and sides.
Check for any objects blocking the sensor paths or the mop area. Clear debris, hair, or obstacles that might interfere with the robot’s navigation or mopping process.
Ensure the obstacle avoidance system is functioning properly; if necessary, recalibrate sensors via the app or reset the device.
3. Update Firmware and Reset the Device
Outdated firmware can cause software bugs affecting mopping. Open the Roborock app and check for firmware updates. Follow prompts to download and install any available updates.
If issues persist, perform a factory reset of the robot. Navigate to settings in the app, select ‘Reset,’ and follow instructions. This can resolve minor glitches affecting mopping performance.
4. Inspect and Clear the Water and Mop Path
Ensure the path for mopping is clear of hair, dust, or debris that could clog the mop mechanism or interfere with proper contact with the floor.
Check the mop lifting mechanism—if it’s stuck or not engaging, it can prevent mopping from starting. Reset the lift if necessary and verify the mechanical parts are functioning smoothly.
Remember to check the vacuum’s brush system for tangles that may affect overall cleaning performance.
5. Test and Final Adjustments
After completing the above steps, run a test cleaning cycle. Observe whether the robot properly mops the floor and adheres to the designated area.
If the robot still skips mopping, try repositioning it on a different area of the floor or resetting the cleaning map in the app. Confirm all updates are installed and settings are correct.
Consistent issues may require contacting Roborock support or replacing worn-out parts like the mop cloth or filters.
