Both models have pretty much the same essential functions. However, Cirrus 2 is further developed, both regarding design and the fact that we have added a coating on the inside of the steamer.
The coating makes Cirrus 2 resistant to residues of limescale and minerals, i.e., it doesn’t require descaling. Cirrus 2 has a mouthpiece in stainless steel to create better friction between the steamer and the fabric.
With the Cirrus 2, you also get a heat protection bag which you can store the steamer in and use as a steaming tool. This bag is not included in Cirrus 1, but you can buy it separately here.
