I haven't seen a new one that doesn't have auto shutoff, but they do vary in the times. I read the instructions before buying last time and was glad that I did. I found one with 15 minute shutoff...most were 8 minutes. I bought a Shark. As for leaks...I don't think one exists that doesn't develop a leak at some point. Even the expensive ones do from what I've read. I seem to be replacing mine annually or so...I limit to about $30-35 because of that.
