Due to the different motion of the sand pad, both tools have different sanding pattern. One advantage with the random orbital sander is, it can clean dust from the sand pad by itself.

Frequently Asked Question:
Q: What is the critical difference between an orbital sander and a Random-Orbit Sander?
A: The orbital sander comes with a circular sand pad, where you attach a disk shape sandpaper. When you turn o the sander, it will start to rotate the disk sandpaper in one direction continuously.
On the other hand, a random-orbit sander has a rectangular sand pad. You can attach any sandpaper matching the pad and lock it into place with built-in clamps. After turning it on, instead of rotation, it moves all the directions randomly.
Q: What kind of Sander should I use to remove stains?
A: In case of removing a stain from wood, a random orbit sander is the best option for you. It has a powerful motor that would be enough to complete the job. Plus, the random moving pattern of the sand pad dramatically helps in preventing the stain from reattaching.
Q: What is grit sandpaper best to remove a stain?
A: It entirely depends on how deep is your stain. Usually, Medium grits sandpaper with rating 120-150 is best for removing old paint. You can start there and move up or down to fulfill your needs. Remember, lower the grit number, the rough it gets. And higher the name means finer sandpaper.
