Kärcher Full Control Rotojet DB 145 Dirt Blaster

The Kärcher Full Control Rotojet DB 145 Dirt Blaster (2.642-728.0) is a heavy-duty high-pressure washer accessory. It works as a rotating nozzle that converts a standard water stream into a high-speed pencil jet. It is designed for Kärcher pressure washers in the K 4 and K 5 performance classes. The rotating action spreads the impact of the high-pressure water over a wider area than a static point jet. It can be used to remove ingrained organic growth, such as moss, and atmospheric pollutants from hard exterior surfaces. It is primarily intended for driveways, paths, and stone walls.

The accessory has a standard bayonet connection for secure attachment to compatible spray guns. It measures 450 mm in height and 41 mm in width and depth. With a total weight of 200 g, its lightweight construction helps keep the lance balanced during extended use. The model is finished in black and fits into existing setups without additional adapters. It is compatible with various series, including the K 4 Compact, K 4 Full Control, and K 5 Premium models. Its shape allows it to reach into corners and tight spaces where larger surface cleaners may struggle.

• Rotating pencil jet — focuses the water stream to break up thick moss and atmospheric grime on hard surfaces.
• Bayonet connection — provides a fast and secure fit to the trigger gun without tools.
• 450 mm length — offers enough reach for cleaning high walls or ground-level surfaces while standing upright.
• K 4 and K 5 series compatibility — the nozzle is calibrated for the pressure output of mid-range Kärcher machines.
• 200 g total weight — reduces fatigue when handling the spray lance during long cleaning sessions.
• Dirt blaster nozzle — designed for hard materials that are not sensitive to high pressure, rather than automotive paintwork.
