Description

Overview
The Simpson Big Brute BB65106 is a heavy-duty, professional-grade cleaning solution engineered to tackle the most stubborn grease, oil, and industrial grime. Delivering a powerful 4000 PSI at 4.0 GPM, this machine combines high-pressure water with an integrated diesel-fired burner system to heat water rapidly, making it exponentially more effective than cold-water units for degreasing equipment and sanitizing surfaces. At its heart is the legendary Vanguard® V400 engine, providing the consistent torque and easy-start reliability required for all-day commercial use in construction, agriculture, and facility maintenance.
Built on a rugged, powder-coated steel frame with a roll-cage design, the Big Brute is designed to withstand the punishment of a job site. It features a premium COMET industrial triplex plunger pump for long-term durability and a high-efficiency vertical coil that ensures a steady supply of hot water. With its oversized 13-inch premium pneumatic tires and balanced weight distribution, this pressure washer offers the mobility and raw cleaning power needed to restore heavy machinery, strip old paint, or deep-clean concrete with industrial precision.
