Regarding this, what does a random orbit sander do?

A random orbit sander works by simultaneously spinning the sanding disk and moving it in an ellipse. The random sanding action prevents swirl marks and the direction of the grain is not an issue when sanding. Random orbital sanders come in 5 or 6 inch sizes that pertain to the sanding disk size used.

Also, does a random orbital sander spin? dia. (6-in. versions are also available), the random-orbit sander spins but doesn't rotate on a single, consistent axis like a typical disk sander. Instead, the shaft spins and also oscillates off center, creating a random scratch pattern that is never exactly the same.

Furthermore, what is the difference between a random orbital sander and a finishing sander?

Orbital finishing sanders use either a quarter, third, or half of a full 9x11" sandpaper sheet, and random-orbit sanders take either 5"- or 6"-diameter discs. For this article, we'll focus on the most popular classes of both types: 5" random-orbit and quarter-sheet orbital finishing sanders.
