The unique water tank's structure of GS2 makes tank capacity twice as big as an ordinary handheld clothes steamer. The tank also can be used as a handle. Moreover, the water tank can be separated from the machine and put into the suitcase to reduce space occupancy, which makes it very suitable for travel. The angle between the aluminum panel and handle makes the ironing process easier. The on-off key is designed at a position where the thumb is free to operate, so people can easily operate it with one hand.
