Why the surface cleaner matters
A surface cleaner is a round hood with a spinning bar and two or more nozzles underneath. It rides on the concrete, so the nozzle height never changes and every pass hits the surface the same way. That is what gives you a uniform finish instead of the arcs and stripes you get from a wand. It also keeps overspray down, which matters on a Miami lot where the neighbour's car is six feet from your driveway. We still use the wand, but for the edges, the apron and the expansion joints where the hood does not reach.
