ABSTRACT:
The invention is directed to an electric toothbrush (1) in which a timing element (13) is provided whose purpose it is to indicate to a user the end of at least one cleaning period when the electric toothbrush (1) is activated. Still further, means (12) coupled to the timing element (13) are provided to enable the user to trigger the beginning (T4) of the cleaning period (PZD2). The effect thereby achieved is that the end (T2) of a cleaning period (PZD1) does not automatically start the beginning (T4) of the next cleaning period (PZD2), but that this particular beginning (T4) of the next cleaning period (PZD2) is freely selectable by the user.
