I disposed of the main unit about six months ago, so I don't know the model number of the cleaner itself. However, the adapter is marked with "217160-04". It was charging without any problems until I got rid of the main unit, but I haven't been able to confirm that it powers on since then. The cord was routed through the bracket, so there's some waviness at the base and some slight scratches on the surface. Please check the photos. I plan to wrap it lightly in cushioning material and ship it via post. Please review my profile before making a purchase. #Dyson #21716004
