There is persistent dirt like bonded pollen film on garden furniture or dirt crusty on flower buckets that can't just be washed away. A good brush must be installed. The WB 24 hand-held washing brush, especially for Kaercher hand-held cleaner, achieves very good results here. The flat jet used first moistens the surface to be cleaned, and then reaches any place with the extra long bristles of the brush head, which can be rotated in 90° steps. Finally, rinse the dissolved dirt with the flat jet and the cleaning action is done. Since water is only used when the trigger is operated on the appliance, water consumption can be controlled very efficiently and individually. In this way, the battery is protected at the same time. Thanks to the proven Quick Connect system, the connection between the washing brush and extension tube can be released with only one hand, in order to change to another handheld cleaner accessory if necessary.
