The Nitecore NIA007 is a vacuum extension kit designed specifically for the Nitecore BB Nano. With its 3-in-1 design, the NIA007 includes a dust bin body, and two vacuum nozzles: an extended nozzle and a brush nozzle. To use, remove the filter at the bottom of the BB nano and then attach the dust bin, rotating it in the direction of the lock symbol until the bin is secure. You can then select your preferred nozzle for optimal cleaning. The extended nozzle is ideal for reaching narrow and hard-to-access areas, while the brush nozzle aids in loosening debris from crevices as you vacuum.
