Our Shark Steam Mop seems to have done kaputz. It doesn't put out steam anymore all of the sudden. I contacted CS and got instructions to try and fix it, but it's not working. It's 3.5 years old, so I'm wondering if it's just time to get a new one. It's just odd that it suddenly stopped working. If you've had a Shark Steam Mop that suddenly died, about how long did you have before that happened? Thanks!
