1. Verify Water Tank and Water Flow

  1. Open the water tank compartment on your Roborock Q10 S5+ and remove the water tank.
  2. Check if the tank is filled with clean water up to the indicated level. Refill if necessary.
  3. Inspect the water outlet and tubing for any blockages or kinks. Clean with a soft cloth or a small brush if needed.
  4. Ensure the water tank is securely reinstalled in the correct position.

Proper water flow is essential for effective mopping. If the system is clogged or the tank isn’t properly seated, the robot won’t dispense water during mopping.

2. Inspect and Clean the Mop Pad

  1. Remove the mop pad from the bottom of the robot.
  2. Check for dirt, hair, or debris that may block water absorption or contact with the floor.
  3. Wash the microfiber mop pad with water and mild detergent, then let it air dry completely.
  4. Reattach the clean mop pad, ensuring it’s secured properly in place.

A dirty or improperly installed mop pad can prevent effective mopping and may cause the robot to skip this step entirely.

3. Confirm Mopping Mode and Settings

  • Open the Roborock app and navigate to your device’s control panel.
  • Ensure that the mopping mode is enabled in the cleaning settings.
  • Adjust the water flow level if options are available, choosing a higher setting for more thorough mopping.
  • Start a cleaning cycle that includes mopping, and observe if the robot begins the mopping process.

Sometimes, the robot defaults to vacuum-only mode if settings are changed or if the user accidentally disables mopping. Double-checking your preferences ensures the robot performs both functions as intended.

4. Update Firmware and Perform a Reset

  1. Check for firmware updates via the Roborock app. Keeping your device updated can fix bugs affecting mopping performance.
  2. If an update is available, install it and restart the robot.
  3. If problems persist, perform a soft reset by turning off the robot, waiting 10 seconds, then turning it back on.
  4. For persistent issues, consider performing a factory reset following the manufacturer’s instructions, then reconfigure your cleaning settings.

Firmware updates often contain bug fixes that improve mopping functions, while resetting can resolve glitches that might be preventing mopping from starting.

5. Additional Tips and Safety Warnings

  • Always use the recommended water and cleaning solutions to avoid damaging the mopping system.
  • Regularly check and clean the water outlet and tubing to prevent blockages.
  • Do not overfill the water tank, as excess water can leak or cause malfunction.
  • Be cautious with cleaning products; use only mild detergents compatible with the microfiber mop pad.
  • If your Roborock has obstacle avoidance features, ensure they’re not interfering with the mopping process by keeping the floor clear of obstacles.

Following these safety tips can extend the lifespan of your robot and ensure safe, effective mopping performance.
