Check the Water Tank and Mopping Settings
- Start by inspecting the water tank. Remove it from the robot and ensure it’s filled with clean water. If the tank is empty or improperly seated, the robot won’t spray water for mopping.
- Reinstall the water tank securely, making sure it clicks into place.
- Open the Roborock app or control interface and verify that the mopping mode is enabled. Sometimes, the robot defaults to vacuum only if the mopping setting is turned off or not configured properly.
- Adjust the water flow level if your app allows, ensuring it’s set to a level suitable for your flooring type.
Addressing these basic setup issues often resolves common mopping failures.

Inspect and Clean the Mop Pad and Brush System
- Remove the mop pad and check for dirt, hair, or debris that could block water distribution or reduce mopping effectiveness.
- Wash the mop pad with mild detergent or replace it if it’s worn out or heavily soiled. The recommended reusable microfiber mop pads can be washed and reused, but should be replaced every 1-3 months for optimal performance.
- Check the main brush, side brushes, and water outlet for tangled hair or debris. Clean them with a brush or cloth, ensuring nothing obstructs water flow or movement.
- Inspect the water outlet for clogs or mineral deposits. Use a small brush or toothpick to clear any blockages.
Keeping these components clean ensures smooth mopping operation and prevents blockages that can halt water spray or movement.
Verify Proper Robot Positioning and Obstacles
- Place the robot on a flat, open floor free of obstacles, cords, or large debris that might interfere with mopping.
- Check if the robot’s sensors are clean. Wipe them gently with a soft cloth to ensure proper navigation and obstacle avoidance.
- Make sure the robot is not in a zone or restricted area that disables mopping functions.
- Run a test cleaning cycle to see if the robot begins mopping as scheduled.
Proper placement and clean sensors are crucial for the robot to perform both vacuuming and mopping efficiently.
Update Firmware and Reset if Necessary
- Ensure your Roborock device has the latest firmware installed. Check for updates via the app and follow prompts to update if available.
- If updates do not resolve the issue, perform a factory reset. Follow the manufacturer instructions for your model to reset settings and calibrate sensors.
- Reconfigure your cleaning preferences and test the mopping function again.
Firmware updates often fix bugs and improve mopping performance, while resetting can clear configuration issues that prevent water spray or movement.
Additional Tips and Important Warnings
- Always use recommended mop pads and water tanks to prevent leaks and damage.
- Regularly inspect and clean the water outlet and sensors to maintain performance.
- Avoid using harsh chemicals or abrasive cleaners on mop pads or water tanks.
- Be cautious when resetting the device; follow manufacturer instructions to avoid voiding warranties.
- If the problem persists, contact Roborock customer support for professional assistance.
Following these safety tips will prolong your robot’s lifespan and ensure safe operation.
