Karcher DB 120 Dirt Blaster Nozzle Rotary Jet K2 – K3 2.642-727.0

Maximum Power for Stubborn Dirt

 

The Kärcher DB 120 Dirt Blaster is designed for the toughest cleaning challenges. By combining the concentrated power of a pencil jet with the coverage of a fan jet, it produces a rotating high-pressure beam that literally "blasts" dirt away. It is the ultimate tool for restoring mossy garden paths, weathered stone walls, and mud-caked equipment.

 

Key Features

• Rotating Pencil Jet: Spins a concentrated water jet at high speed to provide 10x the cleaning power of a standard spray lance.

• Superior Coverage: The rotary action allows you to clean larger surfaces faster without losing pressure intensity.

• Bayonet Connection: Features the standard Kärcher "Twist and Click" system for a secure fit to your trigger gun.

• Compact Efficiency: Specifically calibrated for Kärcher K2 and K3 power classes to ensure optimal pressure output.

   

Ideal For

• Stone & Brickwork: Removing thick moss, algae, and lichen from garden walls and steps.

• Paving & Driveways: Blasting away deeply embedded dirt and oil stains from concrete or stone.

• Hard Surfaces: Ideal for unpainted metal or heavy-duty garden machinery.

 

 Important Safety Note

Do not use the Dirt Blaster on cars, wood, or sensitive surfaces. The rotating jet is extremely powerful and can strip paint from vehicles or splinter the fibers of wooden decks. For cars, use the Vario Power Spray Lance or a Wash Brush.

Frequently Asked Questions

1. Why does my Dirt Blaster vibrate or make a rattling noise? A slight rattling sound is normal—this is the internal rotor spinning. If it stops spinning, ensure there is no grit trapped in the nozzle by rinsing it with clean water.

2. Can I use this on my K5 or K7 machine? No. The DB 120 is specifically tuned for the lower water flow of the K2 and K3 series. Using it on a K5 or K7 can cause back-pressure that may damage your pump. For those machines, you require the DB 145 or DB 180 models.

3. Is this nozzle adjustable? No, the Dirt Blaster is a fixed-power nozzle designed for maximum impact. If you need to switch between high and low pressure, you should use the Vario Power Spray Lance.
