Brush Kärcher 2.644-374.0 compatible with K 2 K 3 K 4 K 5 K 6 K 7

The Kärcher 2.644-374.0 WB 7 Plus 3-in-1 wash brush is an accessory for Kärcher pressure washers K2–K7, designed to combine foam application, high-pressure flat spray and a soft brush in one tool. A lever in the handle selects the required function, and an integrated detergent tank extends working time between refills. The brush is suitable for cleaning delicate surfaces such as paint, glass and plastic and is sized to fit standard Kärcher K-series machines.

Advantages

The three integrated functions eliminate the need to change accessories during cleaning tasks, saving time and simplifying operation. The lever control in the grip allows quick switching between foam, high-pressure flat spray and brush modes. The built-in detergent tank reduces interruptions for refilling, while the soft brush option provides careful cleaning on sensitive surfaces.

How to use

Attach the WB 7 Plus brush to a compatible Kärcher K-series pressure washer following the machine and accessory instructions. Fill the integrated detergent tank with an appropriate cleaning agent if foam application is required. Use the lever in the handle to select foam, high-pressure flat spray or soft brush mode. Operate the pressure washer at the recommended pressure and distance for the surface being cleaned to avoid damage.

Usage recommendations

Use cleaning agents recommended by the pressure washer manufacturer. Test on an inconspicuous area before cleaning large or delicate surfaces. Do not use the high-pressure flat spray mode too close to painted or fragile surfaces; keep a safe working distance and adjust pressure according to surface type.
