These machines are ideal to achieve polished concrete with their smooth grinding finish and the ability to easily replace the diamond grinding wheels to move through the different grit sizes. The four head machines have two of the heads rotating clockwise and the opposite two rotating anti clockwise as well as the turntable rotating and these have the advantage of being very smooth to operate with almost no lateral forces that would require physical effort to control. Planetary concrete grinders leave very few tool marks because they have either three or four grinding wheels turning clockwise and these are connected to a turntable that turns anti clockwise. These concrete grinders are mainly used for general flattening or cleaning of concrete, or they can be used for exposing the aggregate while they are usually not suitable for polished concrete.

Double head concrete grinders are faster than single head grinders because they cover more area with the downside being that they are much heavier to move around and consume more electric power. Larger diameter grinding wheels will leave a flatter finish with less tool marks than smaller diameter grinding wheels, however they will not grind to the bottom of depressions as easily which could leave the floor with many small areas where the floor has not been ground. Single head concrete grinders are low cost to hire, relatively aggressive and easy to handle, but they do leave grinding shoulders otherwise called tool marks which appear as rings when the concrete is wetted or when a sealer is applied.
