Introducing the RocwooD RS780 Petrol Power Washer

If you need a powerful, reliable and versatile petrol pressure washer for home the RocwooD RS780 is built to outperform expectations. Delivering an enormous 3370 PSI of pressure, it provides the cleaning strength needed for even the toughest jobs. Whether you’re blasting ground-in grime from concrete paths, restoring timber decking, washing vehicles or maintaining boats and machinery, the RS780 has been engineered to make heavy cleaning fast, efficient and effortless.

Powerful Engine and Pump Performance

At the heart of the RS780 is a 7-horsepower, 212cc 4-stroke OHV petrol engine. This engine is designed for high performance while maintaining easy starting and fuel efficiency. Working alongside a commercial-grade direct drive brass cylinder axial pump, the washer produces continuous smooth water flow with impressive force. The pump also includes a thermal relief valve, protecting internal components during prolonged use and ensuring long-lasting reliability. This combination of engine strength and pump durability makes the RS780 a true workhorse capable of delivering uncompromising results.

Precision Cleaning for Every Surface

Cleaning control is important, and the RS780 makes it simple with its five professional quick-connect nozzles. These nozzles range from a powerful 0° jet for deep cleaning and paint stripping, all the way up to a 40° spray for lighter rinsing and more delicate surfaces. A dedicated low-pressure chemical jet allows you to apply detergent straight from the machine’s integrated tank, enhancing cleaning power when dealing with oil, grease, mould, mildew or stubborn buildup. Whether your job requires precision, power or gentle washing, the RS780 adapts instantly.

Designed for Real-World Use

Despite its strength, the RS780 is surprisingly easy to manoeuvre. The compact upright design and removable top handle allow effortless storage in a garage, shed or vehicle. Oversized 12-inch never-flat wheels provide smooth handling over gravel, grass, slopes and uneven ground, while the lightweight tubular frame offers stability without unnecessary bulk. The soft-grip handle and rubber feet minimize vibration and help keep the machine steady during operation. Everything has been designed with practical use in mind, ensuring that any user can handle big cleaning tasks without strain.

Quality Construction and Long-Term Value

Every component of this pressure washer is built for durability. The commercial-grade crankshaft and camshaft are engineered for years of operation, while the powertrain delivers a continuous rated pressure of 3100 PSI. A generous 10-metre hose gives you reach across large driveways, patios and work areas without constantly moving the machine. With a flow rate of 9.5 litres per minute and a 1.2-litre fuel tank, the RS780 allows extended cleaning sessions with fewer interruptions. Because it is petrol-powered and fully cordless, you have the freedom to work anywhere—no electrical outlets required.
