There's a large concrete swimming pool at my mom's house that needs
refurbishing, and I'd like to help her bring it back into use. Drain the
water, clean out debris, acid wash, ok sounds relatively simple and cheap so
far. Except the part I'm worried about is the filtration system. It is
very old and rusted in the pool room and I doubt it works. So I can better
"visualize the cost" of this project and keep the cost manageable I figure
I'll use a pool cleaning robot instead to suck up leaves and dirt that fall
inside. But can these things do the whole job in a large pool? Can they
keep up with keeping the pool clean without excessive maintenance? What is
considered the best model these days as a filter system replacement?
