The detail brush combines the effect of a flat-fanned water jet with the mechanical cleaning action of the bristles for thorough cleaning of hard-to-reach and awkward spots, such as on a bicycle. Dirt is loosened and washed away immediately. Since water is only used when the trigger on the device is pressed, water consumption can be controlled very efficiently and individually. This also helps to preserve the battery. The brush is mounted directly onto the gun, and the brush head can be replaced if necessary. The detail brush is compatible with all Mobile Outdoor Cleaners OC 3.
