I have a 24' above ground pool. I am looking for a really good manual vacuum. The robot one that came with it is a joke. I want to actually vacuum the pool myself and am not worried about the extra work. There is a good bit of leaves in it now because of the winter but during the summer hardly any leaves end up in the pool. What do you recommend? How does a leaf canister work? Any assistance would be greatly appreciated. I'm ready to get the pool spotless even though we can't swim in it at the moment. Water is crystal clear, I just have to get the leaves and dirt out of it. Thank you. Don
