5. Operation

The Kärcher WBS 3 offers two distinct jet types for various cleaning needs.

5.1. Activating Water Flow

To start the water flow, press the trigger on the handle of the cleaning syringe. Release the trigger to stop the water flow.

5.2. Selecting Jet Type

The WBS 3 features a 2-in-1 nozzle that allows you to switch between a point jet and a rotating jet.

• Point Jet: For precise, targeted cleaning of stubborn dirt. This jet provides a concentrated stream of water.
• Rotating Jet: For efficient, large-area cleaning. This jet rotates to cover a wider surface, reducing cleaning time by up to 50% compared to conventional sprayers.

To switch between the point jet and the rotating jet, rotate the nozzle head at the front of the syringe. The device's design allows for easy switching between these modes.
