Both models have pretty much the same basic functions. However, the Cirrus 2 is further developed, both in regards of design and the fact that we have added a coating on the inside of the steamer. The coating makes the Cirrus 2 resistant to residues of limestone and minerals, i.e. it doesn’t require descaling. Cirrus 2 also has a mouthpiece in stainless steel to create better friction between the steamer and the fabric.
