In two years, the shaving heads will cut a total of 9 million beard hairs. Replace the shaving heads to restore 100% performance. They are compatible with the 9000 series shavers. The improved solution makes maintaining your Philips shaver easier than ever. You can install the new shaving heads in just two steps, ensuring thorough cleaning of the shaver and optimal daily shaving. The latest Philips shavers feature a built-in reminder function in the form of a shaving unit symbol. This symbol lights up to indicate when you need to replace the shaving heads.

1. Remove the shaving head holder.
2. Replace the shaving heads.
3. Reattach the shaving head holder.
4. To reset the shaver, press and hold the on/off switch for at least 5 seconds.

After replacing the shaving heads, you can reset the reminder function by holding the on/off switch for longer than 7 seconds. Otherwise, the reminder function will automatically turn off after 9 consecutive shaves. To restore 100% performance, you should replace the shaving heads every 2 years.
