The Ryobi Ry80030 Premium Pressure Washer allows users to cut down job time with the power of 3,000 pounds per square inch in a single blast and a maximum water flow of 2.7 gallons per minute. The gasoline-powered pressure washer has a 7-horsepower, 4-cycle commercial grade Subaru engine. It also includes an easy start system and a task match system, which lets the user match different nozzles to specific jobs for more or less pressure. The Twist N’ Store handle turns out 180-degrees for cart-style transport and turns back for space saving storage when not in use. It also features an auto-lock quick disconnect wand coupler, an on-board bucket, dry-storage compartment and a wand caddy. The Ryobi Pressure Washer is available exclusively at The Home Depot, and is UL certified.
