Adjustable Foam Cannon for Karcher K2 K3 K4 K5 K6 K7 | Pressure Washer Snow Foam Lance Kit

This adjustable foam cannon is designed to work with Karcher K2, K3, K4, K5, K6, and K7 pressure washers. It creates thick, fluffy snow foam that clings to your car's surface, lifting dirt and grime for a safer, touchless wash. The 750ml bottle is made from durable PA material, and the kit includes all the adaptors you need for a secure fit.

This foam lance kit turns your pressure washer into a professional-grade cleaning tool. By applying a thick layer of foam, the soap has time to break down road film, bugs, and bird droppings before you even touch the paint. This reduces the risk of swirl marks and scratches, keeping your car's finish looking its best.

The kit features two adjustment knobs. One controls the foam mixture, allowing you to dial in the perfect ratio of soap to water for thick, clinging suds. The other knob adjusts the spray pattern, letting you switch from a wide, gentle fan for the body to a more concentrated stream for wheels and tires. The bottle also has measurement guide lines, making it easy to mix the right amount of soap every time.

With a solid brass construction and chemical-resistant nylon adaptors, this foam cannon is built to last. It supports a pressure range of 100 bar to 200 bar (1400 psi to 3000 psi) and can handle water temperatures up to 60°C. The kit comes with a 1-year warranty, giving you confidence in its durability.

Usage Scenario

After a long drive on a dusty highway, your car is covered in a layer of grime and bug splatters. Mixing a high-quality car shampoo with warm water in this 750ml foam cannon, you attach it to your Karcher K5. With a twist of the adjustment knob, you dial in a thick foam mixture. As you spray the car from top to bottom, a rich, white snow foam clings to the paint, slowly dissolving the dirt and bugs. After letting it dwell for a few minutes, you rinse it off with the pressure washer, revealing a clean surface with no scratches or swirl marks.

Micro Comparison

Unlike basic foam sprayers that produce a thin, watery soap, this foam cannon creates a thick, creamy foam that stays on vertical surfaces. The dual adjustment knobs give you precise control over both the foam density and the spray pattern, which is not always available with standard nozzles. This kit is purpose-built for Karcher K-series washers, ensuring a perfect fit and optimal performance without the need for additional adaptors.
