The investment is quite big, I don't know about maintenance but I would expect these air ducts need to be cleaned regularly. Then you need to switch the hose many times to clean the whole house, right? I'm using dyson v12 slim battery vacuum and I'm quite happy. Battery lasts for almost 50 minutes, it's easy to empty, quite lightweight and the green light illuminating the floor is so useful. I don't see why I would ever consider the central one.
