Griot's Garage Boss Foam Cannon
Transform your car wash into a professional detailing experience with the Griot’s Garage BOSS Foam Cannon, available at Auto Obsessed Canada. Engineered with a precision-machined stainless steel manifold, this foam cannon delivers a lifetime of rich, clinging foam that lifts dirt and grime effortlessly.
Featuring the industry-first Auto-Mix system, you can skip the hassle of pre-mixing—just thread your 35 oz bottle of BOSS Foaming Concentrate, connect your pressure washer, and unleash a blanket of thick snow foam across your vehicle.
Whether you’re using a high-performance gas washer or a compact electric unit, the BOSS Foam Cannon adapts with swappable jets and adjustable spray patterns from a wide 40° fan to a narrow 0° stream. Its proprietary rifled barrel enhances foam density, while stainless steel internals resist chemical corrosion for unmatched durability.
