Well we are moved into our new to us home. Love having a pool, but the previous owners left no pool items. I bought a pole and a leaf bag/catcher and a nylon brush. I know a vacuum is what we need but I have no clue what I need to get. Is it just a hose with a vacuum attachment or something more? Test kit is on its way! Is the vacuum something I can get at the pool store if I tell them what i have?
