K 4 FC

The Kärcher K 4 FC (Foam Cannon) represents a significant step up in power and mobility for the serious DIYer and homeowner.

Built to tackle the larger surfaces of a typical American home, the K 4 FC pressure washer combines 1900 PSI of stripping power with the convenience of a mobile trolley. This is the primary workhorse for the driveway, designed for those who need to revitalize weathered decks, remove years of buildup from concrete walkways, or clean the siding of a multi-story home. The generous 25-foot high-pressure hose makes it easy to clean SUVs, long driveways, and expansive patios without the frustration of constantly moving the machine as you work. The upright design and 2.4-inch wheels are specifically engineered to allow you to move the unit across your property without back strain. Under the hood, the K 4 FC features a premium aluminum pump that provides superior thermal resistance and a long lifespan, requiring virtually no maintenance beyond basic seasonal winterization. The included Turbo nozzle is a game-changer for concrete patios, using a concentrated, rotating jet to blast away deep-seated dirt that standard nozzles might miss. When switching to more sensitive surfaces like painted fences or lawn equipment, the 40° nozzle offers a gentle fan spray that cleans without damage. For a complete finish, the included 0.13-gallon foam cannon allows for effective soap application on vehicles and large surfaces. The K 4 FC is engineered to provide a balanced, user-friendly experience that makes maintaining your home’s exterior faster and more rewarding. WARNING: This product can expose you to chemicals including lead and Diisononyl phthalate, which are known to the State of California to cause cancer.
