I came across this and I have done the process with a small handheld tool and I believe this is what needs to happen to my pool. However HOURS of internet searching has found NOTHING as far as a tool of this nature to use for the job... I have the pads, those are no problem... But so far the only options I have is to drain the pool and get on my knees with an angle grinder or to work with an air powered sander, which I can do underwater but it isn't powerful enough.

This would be perfect for what I want to do.
