Sixteen inches of cleaning path per pass covers a driveway or a patio slab in few strokes. Two rotating nozzles spin at 1450 rpm to spread pressure evenly across that width, which prevents streaking and stripping on concrete and pavers. It is rated for gas pressure washers up to 3000 PSI and connects through a standard quarter-inch quick-connect inlet, so it matches most wands already on hand. Construction combines a stainless steel nozzle, an iron joint and a copper connecting rod, with a scrubbing brush skirt around the rim built for rough surfaces. The disc measures 16 inches across and 5.5 inches tall and weighs 3.7 lbs. Driveways, garage floors, decks and sidewalks all fall within its range.
