The Karcher T150 patio Head ideal for K2 K3 but can change nozzles to suit those K4 K5 machines upto 130 bar. Works fine on my K520 as is. Can add one on for £10 or 2 for £19. The Kärcher Pressure Washer T150 T-Racer Surface Cleaner Patio Head only is a high-pressure cleaning accessory designed for garden and patio maintenance.
