Mulch vacuum
YES, I believe that you can clean ANYTHING with the proper vacuum!
Take a street sweeper truck, modify it so that it has a big hose that you can drag around. Roll up to a property, vacuum up all of the old mulch, flip a switch and blow in all new mulch. Why does this vehicle not exist?
Until then, I will just use my Shop Vac to pick up all the little pieces of old mulch that get washed into the yard…
