This Wolf petrol pressure washer runs on a 9HP, 6.7kW 4-stroke OHV engine and delivers 300 bar at 15 litres per minute, the highest output in the range, built for heavy commercial-grade cleaning of stubborn dirt, moss, algae and grime across large or heavily soiled surfaces. An industrial heavy-duty brass pump handles the sustained high pressure and flow rate reliably. It's self-priming, drawing water directly from a barrel, water butt or open source via the supplied 2m inlet hose and dirty water filter, with no mains connection needed. A 20m steel-inlay rubber hose gives reinforced durability alongside extended reach, suited to larger sites or jobs where the machine can't be repositioned easily. The low oil level shutdown protects the engine if oil runs low mid-job.

Five quick-connect nozzles (0°, 15°, 25°, 40° and detergent) cover everything from tight-angle stripping to a wider fan spray, plus a dedicated detergent setting for the built-in tank on deeper cleans. The frame uses 32mm steel tubing with air-filled all-terrain tyres for stability on uneven ground, and onboard storage for the hose, lance and nozzles keeps kit together between jobs.
