I took no advantage of the shape of the brush. I was cleaning a deck of mold and moss and the turned up, front bristles were not to any advantage. These are stiff bristles so were good for scouring the deck with my home made bleach solution. I cleaned the deck again for a final scrub with a softer flat brush. I used this brush on a regular broom pole without the water wand.Good quality but a flat brush would be more effective IMHO.
