How to get rid of leaves

New homeowner who inherited an above ground pool last Sept. It had been closed for over 18 months until last week when I paid to have it opened. I've been working to clean up the water for the past several days with chlorine and filtration. But I need to know the best way to get the leaves that have settled at the bottom. I purchased a dolphin robotic cleaner but I'm afraid it wont pick up the big chunks. Looking for suggestions. Thanks in advance.
