The noise from your Philips lady shaver is caused by the movement of the trimmer teeth and mechanical system inside the foil. Rest assured, this noise is normal and nothing to worry about.                                                                                                                                                                                                                                                                                     
However, if the sound changes or increases, check whether the device is damaged or needs to be charged. Cleaning the device may also reduce the noise. Follow the tips below on how to properly maintain your lady shaver.
