The Cannon Detailing Circles Talk About. Still.

The MJJC Foam Cannon Pro V2.0 pairs Thicker Snow Foam Technology with a solid brass body, a leak-proof cap and a bottle over a litre — the benchmark the mid-range gets measured against.

Foam is only useful while it's still on the car. Dwell time does the cleaning. That's the whole point of a pre-wash: dense foam clings to a vertical panel long enough to soften and lubricate the grit, so when your mitt makes contact it's sliding over loosened dirt rather than grinding it into the clear coat. The Pro V2.0's foam technology produces noticeably denser lather than standard cannons while using less shampoo, and the bigger bottle means a full car — or a large SUV — gets done without stopping to refill halfway through. Build-wise it's machined brass and resistant nylon rather than plated pot metal, with threads that seal against the bottle and the gun without PTFE tape. The leak-proof cap is the detail owners mention most: it holds even inverted, so no wasted shampoo and no puddle in the boot.

Specifications

This cannon is for cold water pressure washers only and is not compatible with hot water machines. Foam density depends on the cannon, a quality shampoo at the right dilution, and a washer with adequate flow — fit the orifice that matches your machine's output. Confirm the connector fitting matches your spray gun before ordering, and flush through with clean water after every use so dried shampoo doesn't block the filter.
