Karcher Professional Pressure Washer M18 x 1.5 Dirt Blaster Nozzle

Karcher M18 x 1.5 Dirt Blaster Nozzle 

This genuine Karcher Dirt Blaster Nozzle is designed to deliver powerful, targeted cleaning performance for demanding outdoor tasks. Made from high quality materials, it offers excellent durability and a long service life, even when used regularly on tough dirt and grime. Manufactured to Karcher’s exact standards, it ensures reliable compatibility and a secure fit with compatible Karcher pressure washer lances.


10× Better Cleaning Performance

The Dirt Blaster uses a rotating pencil jet that provides up to ten times greater cleaning performance than a standard spray nozzle, making it ideal for removing stubborn dirt, moss, algae, and ingrained grime from hard surfaces such as patios, driveways or stonework. The rotating action delivers intensive cleaning while still maintaining controlled and efficient water use..


Ø35 Nozzle Size

Nozzle size refers to the diameter of the opening through which the water flows, which is a critical factor in determining the water flow rate and the resulting pressure of the spray.

• Smaller Nozzle Size = higher impact, more forceful jet of water.
• Larger Nozzle Size = lower pressure spray but a higher overall flow rate (GPM/LPM)

Using the correct nozzle size ensures optimal performance and safety for both the operator and the machine. Too small and it creates excessive back pressure on the pump, which can strain the motor, potentially lead to long-term damage. Too large and it will result in insufficient pressure, reducing the machine's cleaning power and efficiency. The nozzle size should be matched to your specific pressure washer's flow rate and pressure rating. 


Compatibility & How To Use

This nozzle is compatible with the older style lances that have a M18 x 1.5* connection, simply remove the end of the lance (image 1) and screw on this nozzle in its place (image 2).


*If you are looking to use this nozzle with a EASY!Lock lance, then you will require the following: Adapter 8 (SKU: 8405635)
