The innovative duoSoft hard floor nozzle with gentle brush rollers BBZ124HD from Bosch with two rotating brush rollers is suitable for cleaning valuable hard floors and parquet. It does not push coarser dirt, such as cat litter or road grit, in front of it, but the brush rollers "sweep" it directly into the extra-wide suction channel. The extra-flat design enables effective vacuuming and perfect results even under low furniture, and it also vacuums on carpets, eliminating the need to change nozzles during vacuuming.
