5.2 WPS Cleaning Programs

Rotate the WPS dial to select one of the following programs:

• Intermediate Program (Medium): Suitable for general cleaning tasks including cars, ATVs, motorcycles, caravans, plastic furniture, rendered walls, and brick surfaces. This offers a balanced pressure for effective cleaning without excessive force.
• Intensive Program (Hard): Designed for heavy-duty cleaning of durable surfaces like stone or concrete slabs, railings, metal fences and gates, and gardening tools. This program delivers maximum pressure for stubborn dirt.
