Verify Mop Cloth and Water Tank Setup
- Ensure the microfiber mop cloth is correctly attached to the mopping module. It should sit flat and be securely fastened.
- Check that the water tank is filled with clean water and properly installed in the robot. Sometimes, an improperly seated tank prevents water from reaching the mop.
- Inspect the microfiber cloth for dirt or wear. A dirty or worn cloth can hinder mopping performance. Replace or wash it if needed.
Confirm Water Delivery System Functionality
Roborock’s sonic mopping system relies on a functioning water delivery setup. If water isn’t reaching the mop, the system won’t mop effectively.
- Check the water tank for blockages or clogs in the water outlet or tubing.
- Ensure the water pump is working by observing if water is being dispensed during operation.
- If you notice no water flow, clean the water outlet and tubing thoroughly.
Update Firmware and Reset the Device
Firmware updates often contain bug fixes that improve mopping functions. Make sure your Roborock is running the latest software.
- Open the Roborock app and check for firmware updates.
- If an update is available, install it following the app instructions.
- If issues persist, perform a soft reset by turning the device off and on again or resetting to factory settings if recommended.
Inspect and Clean Sensors and Filters
Dirty sensors or filters can interfere with navigation and water distribution, affecting mopping. Regular cleaning ensures optimal performance.
- Clean the obstacle avoidance sensors with a soft, dry cloth.
- Remove and wash the filters, including the self-emptying station filters, if applicable.
- Check the water outlet for any debris or buildup and clear as necessary.
Perform a Test Run and Adjust Settings
After completing the above steps, run a test cleaning cycle to evaluate mopping performance.
- Start a mopping cycle in the app and observe if water is being dispensed and the mop cloth contacts the floor properly.
- If the robot skips mopping or doesn’t water the floors, verify that the mopping mode is enabled in settings.
- Adjust the mopping intensity or water level if options are available.
If problems continue, consider replacing the microfiber mop cloth with a fresh one, especially if it’s worn out or excessively dirty.
