The white light will flash during charging and remain solid when fully charged. A full charge takes approximately 3 hours.
2. Attach the Nozzle: Insert a desired nozzle firmly into the opening at the top of the device until it clicks into place. Ensure it is securely attached to prevent leaks.
3. Fill the Water Tank: Twist the water tank counter-clockwise to remove it from the main unit. Fill the tank with warm water. Reattach the water tank by twisting it clockwise until it is secure.
