Our Karcher Sweeper has flat pleated filter and fine dust suction for low-dust sweeping, as well as electrically driven sweeper roller and side brush: manual sweeper for easy cleaning indoors and outdoors & sweeping corners. Main roller brush and side brush are easily height adjustable and therefore adaptive to different surfaces. The adjustment of the main roller brush is quickly done by a knob in 6 steps. The 12-V battery and the corresponding charger (230V, safety plug) are on-board.
