My Jandy Ray-vac has serviced my pool pretty well. It began to fall apart (my chems off balance?) bit by bit last season, and now it isn't that effective in making turns, or sucking for that matter. I'd like to replace it, but want to know what the easiest way is. I'm confused with reading some of the recommendations, because they never mention how the equipment gets attached: extra pump vs. no pump needed. I'm guessing my Jandy has no extra pump. It gets a feed from the filter, and the water propels it and causes a suction?

What product can I buy, and just unhook the Jandy, and hook in the new product? How do I classify this type of cleaner?

Thanks for any help.
