A pico-hydro-electric toothbrush has an elongated housing shaped to be grasped by the human hand. The housing encloses a pico-hydro-electric plant which generates the electricity and drives a brush shaft that has a stub projecting through a nose of the housing and upon which in use a brush is mounted. A variety of electric toothbrushes has been disclosed, and has appeared on market. These automatic toothbrushes commonly use a DC motor drive to move the brush holder through a spring mechanism or transmission mechanism. The transmission mechanism can be of any type that oscillates, rotates or vibrates the brushhead. The brushhead, that hold a respective bunch of bristles and are driven to make a circular motion and reciprocating motion respectively for cleaning the teeth in the most efficient way.
