1. Pour water out of the tank.
• Switch on the device and let the remaining water drain out.
• If you have used a liquid other than water, wash the tank thoroughly. Then fill the tank with warm water, point
the nozzle at the sink and allow all the water to drain. This prevents clogging of the nozzle.
2. Press the nozzle release button, remove the nozzle and place it in the case.
3. Clean the device with a soft cloth or a mild, non-abrasive cleaning agent.
