These are parts for Duskin's cleaning robot, Shiro-chan. They are the rotating brush and the dust box. I bought them in August 2021, but I'm not using them anymore, so I hope someone who needs them will be happy to have them. I will ship them out of the box. Please purchase if that's okay with you. This is a robot vacuum cleaner brush featuring blue and purple nylon brushes. Thank you for looking.
