I've seen and held a Cyclo polisher. I decided not to buy it. I personally thought it would be kinda hard to polish or wax a car with. A single pad DA would work just as well. The sales guy also told me he only uses it to scrub carpets. He has two carpet brushes on his and that is all he uses it for.
I got the DeWalt DW443. It is just like the PC but has a bigger motor in it and, IMO, is better built. I've run it for several hours when working on a boat and it wasn't even warm! Very nice machine. It isn't that much more expensive than the PC when ordered off the internet and comes with a velcro backplating.
