A:AnswerNo! That's what is so wonderful about this machine! No permanent lines. You can take it with you anywhere as long as you have an AC plug. Just fill it with water - we recommend filtered water - and turn it on. Ice cubes in less than 10 minutes!
A:AnswerThe ice cubes do not clump together in the maker because there is not a way to keep them frozen after they are made in this product. If you remove them from the maker and place them in a freezer they do freeze together at that point.
