Short answer
A rotary polisher spins its pad on a single axis, with no orbit. Auto Care HQ explains that this builds heat and friction faster, and that rotaries are mostly used by experienced users while dual-action machines are considered safer for beginners. None of our verified sources gives rotary speed or plate specs yet, so check the maker's figures for any model you consider.

Watch out for
- Heat builds faster. Auto Care HQ says a rotary builds heat and friction faster than a dual-action polisher.
- Dual-action is not risk-free either. Milwaukee warns that even its random orbital polishers may cause swirl marks or burning with too much pressure, the wrong angle or improper motion.

Questions
Is a rotary polisher harder to use than a dual-action?
Auto Care HQ says rotaries are mostly used by experienced users, because single-axis rotation builds heat and friction faster, while dual-action machines are considered safer for beginners.[1]
Does a rotary polisher have an orbit throw?
No. It spins on a single axis, so there is no orbit. Throw figures apply to dual-action machines.[1]
