Vortexx Pressure Washers start with precision laser cut aircraft grade 5052 aluminum. Our one piece welded construction means light weight and rust free performance with no bolts to rattle loose. We go the extra mile to powder coat every unit to avoid corrosion and discoloration from chemicals, so it will not only work great, but look great for years to come. We start, pressure check, and test every unit by hand before it goes in the box, which gives us confidence to provide the best combination warranty in the industry. Vortexx even pre-loads Opti-4 performance lubrication to protect your internal engine components and double your engine warranty.
