If you have shop air, then a random orbital sander is very cheap. They work
great, but they need a pretty good sized compressor.

Of course, I also want to use it as a random orbital polisher. I just
want to know if I can also use it as a sander in the way that I have
described above.

Sanding takes a lot more torque than polishing. Maybe it will stall too
easily, or won't keep the random pattern?

There are random orbital sanders, of course. High-horsepower gadgets.
