The older Dyson models came with a charging dock, but for the middle-child in my Dyson vacuum family, the DC-31 didn't come with one.This will work with the DC-35 too but that model already comes with a dockPrint both parts and assemble/glue.You may need to clean up the power adapter hole. When inserted, it should fit snugly requiring a small bit of force to get it into place. The holes in the front allow screwdriver access to the mounting holes.
