Robot mop function does not dispense water; mop pad stays dry.

Safety first: Turn off the robot and remove the water tank.

Basic checks:

• Fill the tank with clean water and ensure the cap is closed properly.
• Inspect and clean the tank filter and outlet holes; remove any debris.

Prime the system:

• On gravity-fed tanks, allow a few minutes of mopping for water to reach the pad.
• On pump-driven models, start a mopping cycle and listen for pump operation; if silent, the pump may be faulty.

If no water flows: Replace the water tank assembly (for gravity systems) or have the internal pump module checked and replaced by a technician.
