What are the reasons one would buy a cyclo over a PC? Is one "better" than the other or are they meant for different applications? Thanks for any advice.
Short answer- It depends. The PC is better if you're dealing with odd contours and/or need the variable speed. The Cyclo's fixed speed does *not* work too well with AIO, for instance.
The Cyclo doesn't bog down as readily as the PC, but you can use 4" pads on the PC to help with the bogging. The Cyclo is more powerful but it's not like a mini-rotary or anything.
If you do a search on Cyclo you'll see we go over this from time to time. What I always get back to is the Cyclo's user-friendly nature. I enjoy using it while I do *not* enjoy using the PC. And the Cyclo is a much more heavy-duty piece of equipment. When I use the PC I can't help but think that I'm using a sander for something it wasn't really designed to do. With the Cyclo, it's a case of using a well designed polisher to do what it's meant to do.
Ideally, there are reasons to have a rotary, a PC, and a Cyclo (or even more than one of each ). But the PC/Cyclo choice is gonna boil down to personal preference. I'd always choose the Cyclo unless I had a specific reason for wanting to use the PC instead.
Skip the PC/Cycle and learn to use a rotary, you'll be done in half the time and none of that annoying vibration. I use a PC to apply wax and really mild polishing but if the car is heavily swirls it's just to slow.
If I had to pick only one machine out of the two, I'd pick the PC since it's more versatile, BUT I own both and couldn't live without either. They both have a place in the detailing world, IMO.
Because they both have their strengths and weaknesses. It's like "why have both open and closed end wrenches?" You can get by with just one or the other, but having both is nice.
I'll use the Cyclo for all post-rotary work (or when I'm not using the rotary) unless a) I can't reach areas with it (I originally bought my first PC for hard to reach areas on my Jag) or b) I want to use products that seem to work better by PC (AIO, Meg's #80). In those cases, I'm glad I have the PC. As with the two types of wrenches, I could get by without one or the other but I like having both (actually all four; I have two Cyclos and two PCs).
Oh, and the Cyclo works much better for removal-by-machine using MF bonnets. The combination of foam pad and MF bonnet seems a bit heavy for the PC and it just "jiggles" if you apply any real pressure. The MF bonnets on the Cyclo, on the other hand, really *remove* product. I think that doing #16 on/off with a pair of Cyclos is downright fun and it sure is quick and easy.
