The Simpson BB65106 Big Brute Professional 4000 PSI Gas-Hot Water Pressure Washer is a powerhouse designed for professionals who demand top-tier performance, unmatched durability, and consistent cleaning results. Engineered for industrial strength cleaning, this machine tackles the toughest jobs with precision — from heavy equipment and construction vehicles to agricultural machinery, concrete surfaces, and commercial facilities.
At the core of the Big Brute is a powerful Honda GX engine, renowned for its reliability, fuel efficiency, and smooth performance. This commercial-grade engine delivers the muscle required to generate a commanding 4000 PSI of pressure and a flow rate of up to 3.5 gallons per minute (GPM), making it ideal for removing stubborn grease, grime, oil, and mud from virtually any surface.
Unlike standard cold-water washers, the Simpson BB65106 features a hot water system that dramatically increases cleaning efficiency. The built-in diesel-fired burner quickly heats water up to 120°F–180°F, cutting through oil, grease, and industrial residue with ease. Hot water cleaning not only improves results but also reduces cleaning time, making this machine a must-have for professional contractors, mechanics, and cleaning crews.
Constructed with a heavy-duty welded steel frame, the Big Brute is built to endure years of demanding use in commercial and industrial environments. The durable design is complemented by pneumatic tires that allow easy mobility across rough terrains such as construction sites, garages, and farms. The high-quality powder-coated finish protects the frame from rust and corrosion, ensuring long-lasting performance even in harsh conditions.
This machine is equipped with a commercial-grade triplex plunger pump that provides exceptional durability and consistent water flow. The pump features a thermal relief system to prevent overheating and extend lifespan, even under extended use. The adjustable pressure control allows you to fine-tune the output for different applications — from gentle rinsing to blasting away deep-seated contaminants.
The Simpson Big Brute BB65106 is designed for operator convenience and safety. The ergonomic spray gun with a 48-inch lance ensures comfortable operation and extended reach, while the 50-foot steel-braided high-pressure hose offers flexibility and resistance to abrasion. The quick-connect nozzles make switching between spray patterns fast and effortless, helping you move from delicate cleaning to heavy-duty blasting in seconds.
For added reliability, the fuel tanks for both the engine and burner are designed for efficiency and extended runtime, allowing professionals to work longer without interruption. Maintenance is straightforward thanks to easy-access service points and clear labeling on all major components.
