Background: I have a 22000 in-ground vinyl pool with a sand filter, lots of leaves, dirt and pollen falling in my pool, and not much money. The pool has a suction line (?), but I don't like the idea of a booster pump (one more thing to break). With so much debris, I wind up vacuuming all the time, and it's making me dislike my pool.
I think a pool cleaner is the solution. My budget is under $500. I don't mind brushing the pool steps and walls, so I'm not sure that I need something that climbs walls. (Why is that important?) I really like what I read about robots, but unless I buy a used one, I can't afford it. Is buying a used robot a good idea? Or should I buy something new but less powerful, that comes with a warranty? What do people recommend for my situation?
I appreciate all your ideas and input! (Even if it conflicts with someone else's!)
