If you're expecting an organized set of parts for Roomba, you will be disappointed. All things were thrown in the same small bag in a jumble. The bag it was all in was small so the dirt bags didn't fit in and they lay in nothing. They were just thrown away. I just took everything and threw it in a box. I don't even know if everything is there that should have been there. I'll have to disassemble it and have a look. It's just the way I prefer to receive the things I buy.
