Step 2: Inspect the Water Tank and Delivery System
- Remove the water tank from the robot and check for any blockages or leaks.
- Refill the tank with clean water, ensuring it’s properly seated back in place.
- Check the water outlet and delivery port for clogs or mineral buildup—use a soft brush or compressed air if needed.
- Test the robot’s mopping function to see if water is evenly dispensed.
If water isn’t flowing correctly, your robot won’t be able to mop. Regular cleaning of the water delivery system helps maintain consistent performance.
Step 3: Update Firmware and App Settings
Ensure your Roborock Q10 S5+ has the latest firmware installed. Use the Roborock app to check for updates and install them if available.
Open the app, navigate to your device, and verify that the mopping feature is enabled in settings. Confirm that you’ve selected the appropriate cleaning mode with mopping activated, and that no no-mop zones or restrictions are in place.
Sometimes, outdated firmware or misconfigured app settings can cause the mopping function to fail or be disabled.
Step 4: Clean Sensors, Brushes, and Water Ports
- Turn off the robot and carefully inspect the sensors for dust or smudges. Clean with a soft, dry cloth.
- Remove the side brushes and main brush to clear hair and debris tangled around the axes.
- Check the water ports on the bottom for blockages, cleaning gently with a soft brush or toothpick if needed.
- Ensure the obstacle avoidance sensors are unobstructed to prevent navigation issues that might affect mopping.
Proper maintenance of these components ensures the robot’s systems work seamlessly, including its mopping feature.
Step 5: Test and Confirm Mopping Functionality
After completing the above steps, run a test cleaning cycle with mopping enabled. Observe if the robot dispenses water and moves correctly over the floor.
If the robot still doesn’t mop, revisit each step or consider resetting the device to factory settings and reconfiguring your preferences.
Persistent issues may require contacting Roborock support or replacing parts such as the mop cloth or water tank.
