The Karcher DB 120 Dirt Blaster Lance (Rotary Power Jet Nozzle Lance) is the ideal upgrade for users of compact Kärcher pressure washers who need maximum cleaning power on tough, stubborn outdoor dirt. Often called a turbo nozzle, rotary jet lance or power jet nozzle, this Dirt Blaster uses a rapidly rotating pencil jet to deliver far more impact than a standard spray lance.
Designed specifically for Karcher K2 and K3 Series machines, the Karcher DB120 Dirt Blaster generates an intense, concentrated spray pattern that quickly removes ingrained grime, moss, algae and weathered dirt. Its rotating jet technology greatly increases cleaning efficiency, making it ideal for patios, paving slabs, brickwork, concrete, stone, steps, tools and other hard-wearing outdoor surfaces.
The DB 120 Lance delivers full-power cleaning and is intended only for surfaces that can tolerate high pressure. It is not recommended for paintwork, vehicles, softwoods, plastics or any delicate materials. When used on appropriate surfaces, however, it can dramatically reduce cleaning time and effort.
What’s the difference between the DB 120 and the DB 145 or DB 180?
The Karcher DB 120 Dirt Blaster is designed for Karchers entry-level pressure washers such as the Karcher K2 and K3 Series. All Dirt Blaster lances share the same design and use a rotating pencil jet, but the DB 120 is tuned specifically for lower water flow and pressure levels while still offering strong, effective cleaning performance.

- High-Impact Cleaning – ideal for patios, paving, stone, concrete, brickwork and steps.

- Fast Dirt Removal – cleans much faster than standard adjustable lances.
- Perfect for Hard Outdoor Surfaces – designed for durable materials that can withstand high pressure.
- Durable Construction – built to handle repeated high-pressure cleaning.
- Not Suitable for Delicate Areas – full-power jet is too strong for paintwork or soft materials.
If you need powerful, time-saving cleaning performance from your compact Kärcher pressure washer, the Karcher DB 120 Dirt Blaster Lance delivers outstanding results on tough outdoor surfaces.
