Right now rotary is the king of heavy paint correction / renovation just because other machines do not put emphasis on power but on safety and try to balance that. However, raise power/speed on Cyclo a bit, put slightly larger pads, and you are giving a rotary run for it's money while still staying safe, just like that Swedish unit is doing (too bad it is outrageously expensive). Such designs (with 3 heads) are being used to get perfect polish of stone.I tried to compare apples with apples, if you put a rotary in the mix it is matchless for paint correction / renovation. The Cyclo /PC / UDM were not made (or IMO successfully adapted ) to do that type of work
