Just throwing my $.02 in--I would strongly encourage you to add a cleaner to the package, especially if you have large trees on the property that you're not cutting. I have no trees whatsoever in my back yard, but my next door neighbor has a forest in hers, so I end up with a pool full of leaves every time we have a storm with wind. Having a cleaner will save you hours of upkeep time that you could be spending doing something else!!
