Roomba 780, purchased new, has been stored unused since moving. The unit powers on and the display lights up, indicating it is receiving power, but the battery is unusable, so I am listing it as junk. There is a good chance it can be used if a new battery is purchased. The battery has some leakage and is not included. Unused accessories, consumables, and a purchase bonus filter are included, so I hope you can utilize them for parts or consumables.
