Both models have pretty much the same basic functions. However, the Cirrus No.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 No.2 resistant to residues of limestone and minerals, i.e. it doesn’t require descaling. Cirrus No.2 also has a mouthpiece in stainless steel to create better friction between the steamer and the fabric. With the Cirrus No.2 you also get a heat protection bag which you can store the steamer in and also use a steaming tool.
