Hi Glowing.
All heads come with wicks--some, like the bottom coil models, have very short wicks; the top coil models come with long wicks.
All wicks and coils need to be cleaned, eventually. How often depends on how clean your juices are, how much you vape, etc. I don't dry burn my coils at all; I just soak the coil heads in PGA (vodka, denture/retainer cleaning solution also work well). The long wicks should be rinsed thoroughly under warm water and dried (either with paper towels or air dried).
Good luck.
