Same rotary principle as the standard dirt blaster, in a larger orifice intended for machines with more flow.

Matching nozzle to machine

The orifice, the pump’s flow and the resulting pressure are one system. Kärcher’s own accessories are labelled by machine range for exactly this reason. If a nozzle makes your washer cycle on and off, or the jet feels soft on a machine that was fine before, the size is wrong — not the pump.

Same rule as every rotary nozzle

Hard mineral surfaces only. Concrete, block paving, stone, drains. Never decking, render, paint or anything with a joint that water can get behind.
