The geared random-orbit machine, which is three tools in one: a rotary mode that removes material at a rate an ordinary orbital sander cannot approach, a random-orbit mode for finishing, and a polishing mode. The gearing is what makes the difference — in rotary mode the pad is driven rather than free-spinning, so it keeps cutting under pressure instead of stalling. That makes it the machine for stripping old finish, levelling filler, and taking down a surface fast, then finishing the same surface without changing tools.
