I have a lot of leaves (I mean a lot) to clean up in the fall. Over 20 large oak trees in my lawn area and surrounded by oak trees around the perimeter of what I consider lawn. I use a leaf blower around the house. I use wood mulch, and aside from normal decomposition, I invariably blow mulch out of its borders where I then clean up the leaves by either raking and hauling, or by use of a powered leaf catcher. Either method results in loss of mulch to some degree making routine replacement something Ronnie is trying to avoid.
I suspect that unless the rubber mulch is a "mat" when installed, anything that may be loose would result in a loss by means of clean-up and then necessary replacement anyway.
