I'm considering one of these, but something I can't find in most of the reviews is a clear description of how you get the steam - in particular, I want to know if you have to hold a button down continously to get the steam. My handheld vacuum is like that, and my thumb joints can't hand it, as they are very hypermobile. So I am looking for one where you can put a switch on or off to get the steam.
do any of yours have that feature, and if so, what brand/model are they? Do you recommend it?
