This is a set of accessories for a Shark stick vacuum cleaner, including the stand charger, battery, motor head, and filters. The main unit broke, so I can't use it anymore, but the accessories are still usable, so I'm selling them as a set. I bought it new, and sand got into the motor shortly after, so I couldn't use it much. Therefore, I don't think the battery has deteriorated. The filters are also clean.
