2. Insert the detergent suction hose into the detergent container.
3. Set the Vario Power spray wand to the lowest pressure setting (detergent mode).

4.4 Cleaning Tips for Various Surfaces

• Cars: Use a wide spray pattern and a car-specific detergent. Keep a safe distance to avoid damaging paint.
• Decks & Patios: Start with a lower pressure setting and gradually increase if needed. Work in small sections, overlapping slightly.
• Driveways: For tough stains, use a concentrated spray or a dirt blaster nozzle (if available as an accessory).
• Siding: Always spray from top to bottom to avoid water getting behind siding panels. Use a wide, gentle spray.
