Recommendations

For best results, remove small obstacles and loose cables from the floor before cleaning, empty the dust container regularly, and refill the water tank only with clean water. Use the wet mopping function on sealed hard floors and avoid using on unsealed wooden surfaces. Follow the manufacturer’s maintenance instructions to ensure long-term performance.
