A:AnswerThere is a small funnel that needs to be cleaned after every 4 bottles. The machine stops working until the funnel is removed and cleaned. The top part that holds the formula only needs to be cleaned once a month. For the convenience of how it makes bottles, the cleaning requirements are minor in comparison.
A:AnswerYou can use any bottle. There is an adjustable/removable shelf that you can either use, or not, depending on the size of bottle or cup you use.
