Welcome to TFP!
It helps a great deal to rake leaves off of the cover before removing it. You also want to fold the cover into a bag, and then pull off the full bag. First, fold the cover in half by pulling one of the short edges across the length of the pool to meet the other short edge. Then grab the folded corners and pull them about half of the remaining distance towards where the two edges just meet up. That will create a kind of pocket for all the debris to sit in. Then you grab hold of all the layers of cover you can and haul the whole thing out of the pool, go as slow as you can to let water drain out. It doesn't work every time, but with some practice it can work.
