Portable friction cleaning-polishing device essentially characterized by the fact that, starting from an electrically driven motor element, this motor extends its axis in one direction in such a way that it is integral with a second axis retractable to the pressure, for which reason it is constituted by two cylindrical sections, embedded one inside the other, with a device that limits the travel of that one, and with a spring that remains inserted between the end of the embedded section and the axis of the motor proper, and located inside the section that receive the previous one.
