Kärcher FJ6 Foam Cannon for K1-K5 | Easy Vehicle Cleaning

Kärcher FJ6 Foam Cannon for K1-K5 Electric Pressure Washers

Transform your cleaning routine with the FJ6 foam cannon. Designed to pair with K1-K5 electric pressure washers, it applies a thick, clingy foam that helps loosen dirt before you rinse. The 20-ounce reservoir means fewer refills during bigger jobs, so you can cover larger surfaces with confidence. To use, pour Kärcher detergent into the foam nozzle, add water if you’re using concentrated detergent, attach the nozzle to the pressure washer gun, and pull the trigger. The yellow dial on top adjusts how much soap is released, while the spray level can be fine tuned to suit the surface and soil level. This setup keeps things simple and efficient, letting you move from washing to rinsing with ease.

Beyond cars, the FJ6 excels on garden furniture, siding, stairways, RV exteriors, driveways, paths, walls, patios, and more. The foam’s thickness helps it cling to vertical surfaces and crevices, giving grime a head start before you rinse. The nozzle is straightforward to assemble and operate, turning a standard pressure washer into a versatile cleaning system for a variety of outdoor tasks.
