5. Maintenance and Cleaning

5.1 Daily Cleaning

After each use, turn off the device and empty any remaining water from the tank. Rinse the water tank thoroughly with clean water. Allow the tank and the main unit to air dry completely before storage to prevent mold growth.

Remove the nozzle after use and rinse it under running water. For deeper cleaning, soak the nozzles in a cup of white vinegar for 5-10 minutes, then rinse thoroughly.
