Look what it did......
A Kersten powered sweeper with a collector and a side gulley brush sweeps the detritus that the moss is growing in and collects the debris in the collection box. This surface may now dry much more quickly as nothing remains to store moisture reducing the possibility of future moss growth. A periodical sweep will keep this area free from moss and weeds.
