Random orbital sanders can approach the aggressiveness of a belt sander, but are not as risky. That is, you can use them to generate fine finishes, whereas a belt sander could blow through the material if attempting to use it for the same job.
These sanders are similar to orbital sanders except there are two areas of rotation. Rather than the circular movement of an orbital sander, a random orbital sander spins the disk in a circular motion while moving the entire disk on an elliptical path. This dual movement prevents the disk from ever moving in the same path, creating a smooth, swirl-free finish on your work. This is also why you don't need to be sensitive to the wood grain while using one of these tools.
