series1- Yeah, the Cyclo is, IMO, a great tool. It's more powerful than the PC, but the PC can come *close* if fitted with 4" pads. There's no comparison IMO between the Cyclo and the PC *when fitted with large pads*. With 6" or larger pads, the PC bogs down much too easily and the Cyclo is just in another league.
Biggest thing about the Cyclo for me is the user-friendly nature of it. I genuinely enjoy using the thing, which is more than I can say about the PC. All but one of the people I've introduced to the Cyclo and PC prefer the Cyclo.
The Cyclo's speed will fluctuate between ~2,800-3,200 OPM depending on load. But it seems much "faster" or "more powerful" than the PC at most *any* speed. Example- the Cyclo is not well-suited for AIO, it "flashes" it too fast despite its relatively low speed (you can apply AIO with the PC at a higher speed with no problems). There's *something* going on there for it to act that way with the AIO, something more than just speed.
The Cyclo will last forever. Mine suffered greatly in a commercial environment for a few years when we had the dealership (once left outside all weekend in the middle of winter, had to dig it out of the snow

) and was used for about 20 years with *no* service/maintenance at all. When I sent it in for a going-over they said it didn't *really* need anything, but they did clean and lube it and maybe did something else minor (I forget, no biggie whatever it was).
The carpet brushes for the Cyclo work great. You can really put some weight on it and they'll *scrub*. I haven't tried a brush on the PC, but I can't imagine it comparing.
But no, it's not a rotary. I can't do serious correction on hard paint with the Cyclo. But then I haven't tried it with products like Hi-Temp Medium Cut and I haven't used the orange pads either.
FWIW, I wouldn't hesitate to buy a used on and have it refurbished as needed. The turnaround time is quick and the work is reasonably priced.
