A portable polishing apparatus having an electric motor with a housing, a polishing wheel assembly detachably secured to the lower end of the electric motor shaft, and a handle grip secured to the electrical motor housing. The handle grip is in the form of a steering wheel with its arms secured to the motor housing that is positioned within the perimeter of the steering wheel. The center of gravity of the polishing apparatus lies below the horizontal plane of the steering wheel thereby causing the polishing apparatus to automatically right itself any time a tipping force is removed therefrom. The steering wheel has an outer diameter greater than the diameter of the polishing wheel assembly thus facilitating the tilting of the polishing apparatus when desired. The polishing assembly has an eccentric orbital member and a polishing wheel.
