Could anyone who uses a Surge milker tell me how easy it is to clean? Finally I can afford one, but i'm wondering whether the clean-up takes longer than just milking by hand. I currently have two does in milk, but have three other doelings. I'm trying to weigh up whether to stick to two or three and hand-milk, or keep more does and use a machine. I know i'm not going to hand milk 5 does twice a day!
