Even though it is fully automated, this coffee maker is considerably easy to clean than other coffee makers on the market. You will, however, have to do some work yourself, but the built-in cleaning system is also very effective. Make sure you're using filtered water to avoid internal scaling. To avoid a build-up, soak and rinse the milk frothing. In order to avoid blockage, you should replace the milk tube every 6 to 8 months. Finally, clean the frothing attachments and milk tubes after each usage.
