Yes, they are. All you have to do is – unplug the device, remove the detachable components (basket, decanter). Run these components under tap water and dry them. Some of these parts can be dishwasher safe as well. Never place the entire machine under water. The outer part apart from the detachable components can be wiped once in a while using a wet cloth. Make sure to clean the components properly to avoid bitter taste in the coffee.
