For normal brush attachment, a clear difference should be noted: The cleaning is very gentle, the effect is very good.
The cleaning brush is used by my wife usually only after cleansing your face with plain water. Then the sensitive attachment is used. Here a slight massaging effect can be observed. That's nice, but can lead to long application to mild skin irritation or redness.
The bristles are cleaned after use with plain water - let it dry - ready.
In itself a good, sensible product - if it were not so expensive. Therefore, for the price I subtract a star. This also calls for my wife!
