Hi: I have a plaster pool. My brush (the one I attach to the long pole) seems to be worn out and the bristles on the ends are no longer there so that I can't clean in corners with it. Most of the replacements I have looked at seems flimsy and the bristles don't seem as firm as what I have (perhaps they are made for vinyl pools?). I also would like to get a hand-held brush that I can use for where the steps meet the plaster wall. Does anyone have a recommendation for a good replacement? I would rather pay a bit more and get a good one.

Thanks.
