The Kärcher FJ 3 is a foam jet designed to simplify the cleaning of vehicles, facades, and garden furniture by applying detergent evenly across surfaces. This compact accessory features an integrated 0.3-litre transparent container, which allows you to monitor the remaining cleaning agent at a glance while you work on paintwork, glass, or stone paths. Weighing only 0.1 kg and measuring 118 x 93 x 118 mm, this anthracite-colored tool is compatible with Kärcher pressure washer classes K 2 through K 7. If you are using an older trigger gun from before 2010, such as models M, 96, or 97, you will need to use an Adapter M (2.643-950.0) for a proper fit. For the most effective results when cleaning caravans, driveways, or blinds, the Ultra Foam Cleaner is the recommended detergent to use with this system.
