Dirt blaster, for stubborn dirt:
The jet rotates at high speed and achieves a
very high impact pressure so that it has a very
good cleaning effect. Suction of cleaning agent
is not possible when using the dirt blaster.

Rotating cleaning brush: Thorough but gentle.
The brush is driven by the high-pressure jet
which results in a high gloss finish without app-
lying any effort.
