We had many years an ultrasonic cleaner in one piece. Eventually, he stopped going, probably has penetrated somewhere in the casing moisture. This is not so easily possible with this ultrasonic cleaner because the water tank can be removed by the handle. The function is similar to a kettle where the pot can also be easily removed. The device base can remain standing, the container can be removed and easily emptied and refilled. But glasses should not be cleaned several times a day with it because small scratches can be increased quickly by the ultrasonic power and lead to spots on the sensitive glasses. But once a week harm in the long run not to remove the fatty deposits. Then simply rinse with hot water and dry carefully. The device is highly recommended.
