I have a Shark Professional, it is 1800 watt so it gets hot enough. There are 2 ways to steam, one is constant and the other is the shots of steam. I have been using it now for 7 months and like it very much, but I primarily use it without water, it doesn't have the teflon on it. You do have to "cure" it first, if you don't it doesn't seem to get hot and stay hot. It drove me crazy until I read the directions. I was trying to turn off the automatic shut off and found out what I had to do first.
