Electric toothbrushes with auto frequency control
Auto frequency control
— a function found exclusively in toothbrushes with sonic and ultrasonic operating principles (see "Brushing technology").The auto-adjustment feature operates based on the principle of automatically configuring the optimal oscillation frequency depending on the selected mode. However, the specific implementation of this function can vary. Some models are limited to preset frequency values, while others offer manual adjustments if desired. Additionally, control methods may differ; for instance, certain brushes employ "smart" nozzles that trigger the corresponding mode when attached. Nevertheless, automatic frequency control streamlines the user experience by eliminating the need for unnecessary setting adjustments.
