The steamer holds about 3/4 a cup of water. The power button is on the end of the handle. It has a temperature indicator light that goes out once it’s heated up. It has a steam lock button so if you’re steaming a large area you don’t have to hold in the button. The sole plate of the iron is super smooth and glides over the fabric. You can press the steam button while ironing. This is great for travel or small spaces.
