The Karcher FJ 10 C Snow Foam Lance Ultra Foam Cleaner Kit (Pressure Washer Foam Sprayer Kit) is designed for users who want quick, effortless and highly effective foam application. Whether you call it a foam sprayer, snow foam nozzle, foam jet attachment or pressure washer detergent foamer, this kit delivers thick, clinging foam that improves cleaning results while reducing the risk of scratches.
This kit includes the Karcher FJ 10C Foam Lance and a bottle of Karcher Ultra Foam Cleaner. The Ultra Foam detergent supplied is a specially enhanced formula designed specifically for use with foam lances. While most Kärcher detergents can be used through a foam sprayer, Ultra Foam Cleaner is the only Kärcher detergent engineered to produce maximum foam thickness, stability and cling when aerated through a lance, ensuring superior dwell time and improved pre-wash performance.
The Karcher FJ10C Foam Lance features Kärcher’s quick-change bottle system, allowing you to swap between different detergent types in seconds without the need to screw or unscrew bottles. This makes it ideal for users who regularly switch between car shampoo, bike cleaner or general-purpose foam detergents and want a faster, more convenient cleaning routine.
The FJ10C Foam Sprayer Head produces dense, aerated foam that clings to surfaces, helping detergents work for longer to break down dirt, salts, traffic film and grime before contact washing. Its adjustable spray pattern and detergent flow control allow you to customise foam output to suit your cleaning task, whether you're preparing a car, van, motorbike or outdoor surfaces.
What’s the difference between the FJ 6 and FJ 10 C?
The main difference is the connection method. The Karcher FJ 6 uses a traditional screw-on bottle, while the Karcher FJ 10C uses a fast quick-change system designed to let you swap detergents instantly. The FJ 6 is ideal for general use, but the FJ 10C is perfect for users who want maximum convenience and frequently change between different cleaning solutions.
