    摘要: An autonomous device is adapted to automatically move on a work surface removing dirt, such as gravel, sand, dust particles and the like, from said work surface. The device comprises a chassis provided with wheels and with a brush roller rotated by a drive motor during said movement for the purpose of brushing up the dirt towards a suction duct wherefrom, by means of a suction air stream, the dirt is conveyed to a dust container. An electronic control device is provided for the control of the drive motor of the brush roller. If the movement of the brush roller is blocked or obstructed to a predetermined extent the control device is arranged to stop the brush roller motor and then transitorily activate the motor in the opposite direction and, finally, after another stop, to reconnect the brush roller motor to operate in the original direction of rotation.
