Both of our hand steamers Cirrus No.1 and Cirrus No.2 produce 15 to 20 grams of steam per minute. Although the most important thing for a hand steamer is that the steam produced is evenly distributed during usage and not how much steam produces a minute. The steamer will not be perceived as effective if the steam flow is not even. The steam quality is also very crucial. Effective steam is preferable to a lot of steam. We have invested in developing steamers that produce dry and hot steam because then not as much steam is needed to get the results wanted and one tank of water will last longer.
