Any low speed rotary will do the job, you can pick them up from ebay for nothing, I got ours, a numatic for £60 with hard and soft brushes and driveboard. Anything too fast and you will spray stripper all over their walls, been there done it
It's also good to have a wet and dry vac, or you could use your CC machine with a hard floor tool/attachment for sucking up the stripper.
