You said "RPM", which suggests to me that it operates in a rotary motion, rather than an oscillating motion (which would be OPM). If you are new to detailing (obviously you are new to this site) then you probably don't want to use that polisher on your paint or anyone else's. Rotary polishers can be dangerous to paint if they are in the wrong hands. I would recommend getting an orbital polisher instead, which is very safe for beginners.
The speed is okay as long as it does not go beyond 2000 rpm. and is VARIABLE (meaning, aside from the speed setting 1-6, it must also control accelerating speed from the trigger, just like the 9227c)
But if you're new to rotary (a powerful machine), don't even think about it.
