Kärcher 2.644-423.0 pressure washer accessory, brush, 53 mm

The Kärcher 2.644-423.0 scrubbing brush attaches directly to the trigger gun of OC 3 mobile outdoor cleaners and combines a pressure jet with bristles to loosen and wash away stubborn dirt. With a working width of 53 mm and compact dimensions (depth 169 mm, height 21 mm), the brush is intended for quick, targeted cleaning of small to medium surfaces such as garden furniture and bicycles while allowing controlled water use and preserving battery life.

Advantages

The brush delivers strong cleaning power by combining a pressure jet and mechanical scrubbing, while its anti-slip profile and ergonomic shape provide a secure, comfortable grip during use. Water flow is only active when the trigger is pressed, enabling efficient and individual water consumption control. The accessory is lightweight and compatible with all OC 3 mobile outdoor cleaner models.

Recommendations
