Top 3 Frequently Asked Questions
-
1. What makes a "Water-Cooled" motor better than a normal one? Most pressure washers use a fan to blow air over the motor (Air-Cooled). Kärcher’s WCM tech uses the water entering the machine to cool the motor first. This is more efficient, makes the machine 10% quieter, and allows the motor to last up to 5 times longer.
- 2. Can I use the Dirt Blaster nozzle on my car? No. The Dirt Blaster is a rotary nozzle that produces a high-impact rotating jet. It is designed for hard surfaces like stone or concrete. For car paintwork, always use the Vario Power Spray Lance on the "Medium" or "Soft" setting.
-
3. How do I apply soap with this machine? The K4 WCM has a transparent suction tube at the back. Simply drop this tube into a bottle of Kärcher detergent (like the 3-in-1 Car Shampoo) and set your Vario Power Lance to the "Mix" (lowest pressure) setting.
