The short answer for both questions is ...NO!!
The long answer is the PC can do almost as much as a rotary in the proper hands. It takes technique, pads, product and time. It has a learning curve to get results but is much safer than using a rotary.
The rotary will get results faster. It also has a learning curve. Which, in the wrong hands, can be deliterious to a vehicle's paint. With that said, if one keeps moving and does not put to much pressure while operating a rotary, most can learn how to operate a rotary with time, practice and the use of some common sense.
The cyclo is the third of a trilogy of PC, rotary, then cyclo. It is more powerful than a PC. It only has one speed. It employs two four inch pads instead of one pad as do the PC and rotary. It has a different feel to it, compared to the others, but is mastered easily. Cost is the only reason that I do not have a cyclo..... yet. My rotary and PC do me well.
