Kärcher K 2 Battery Cordless High-Pressure Cleaner (Bare Tool, 18V Battery Power)

The Kärcher K 2 Battery redefines portable cleaning by combining cordless freedom with the trusted performance of a Kärcher high-pressure cleaner. Unlike conventional electric models that tether you to a power outlet, this unit runs on the Kärcher 18V Battery Power platform, allowing you to clean anywhere—from garden furniture and bicycles to balconies and caravans—without hunting for a socket. The bare tool configuration means you can use existing batteries from your Kärcher 18V cordless tools, reducing cost and clutter. With a compact, wheeled design and integrated accessory storage, it’s ready to go whenever you are.

• Cordless operation with Kärcher 18V Battery Power platform (battery and charger not included)
• Max pressure of 110 bar and flow rate of 340 l/h for effective cleaning
• Up to 20 m² area performance per battery charge (with 5.0 Ah battery)

In daily use

Whether you’re rinsing off muddy boots after a hike or refreshing patio furniture before a barbecue, the K 2 Battery delivers consistent cleaning power without the hassle of cords. The Vario Power lance lets you adjust pressure on the fly, while the Dirt Blaster provides a concentrated jet for stubborn grime. The 4-meter high-pressure hose gives you ample reach, and the integrated water filter ensures reliable operation even with less-than-perfect water sources. With a sound power level of 86 dB(A), it’s relatively quiet for a pressure cleaner, making it suitable for residential areas. Battery runtime varies by battery capacity: expect approximately 10 minutes with a 2.5 Ah battery and 17 minutes with a 5.0 Ah battery—enough for quick touch-ups or small cleaning tasks.
