Oak trees and pools: like hair and chewing gum

[BigDave]

My AG is under pin oaks. In the sping, they drop flowers (I think they're flowers) then tons of pollen and pollen strings. Little (and sometimes big) sticks all year long. Leaves and acorns all summer and fall. Leaves continue to fall 'til January.
My solution: Robot Cleaner - realtively cheap and picks up almost everything the trees drop in (except big sticks).
