We have a large, dished out to almost 6 foot, above ground pool. I am hand vacuuming it right now - and I don't mind that - but it is hard to get up all the leaves that way. I generally find it relaxing when I am not dealing with spring leaf and seed drop. We have a Hayward Ladybug that came with the pool but that never covers the entire pool and has trouble getting up even fine silt - forget leaves. I am just wanting to make sure that we find a vac that won't damage the pool liner.
