Abstract: The invention relates to a small electrical appliance, for example an electric toothbrush (1), with two elements to be driven and with an electric motor (10). The small electrical appliance has a device (16.1; 16.2; 16.3) that drives the first and/or the second element depending on the direction of rotation of the electric motor (10). The first element to be driven can be a movable brush head (2), and the second element to be driven can be a pump (7, 14) for conveying a care agent to the brush head (2) from a reservoir, wherein the device (16.1, 16.2, 16.3) drives the brush head (2) in both directions of rotation of the electric motor (10), but drives the pump (7, 14) only in one direction of rotation of the electric motor (10).
