For about 3 years, at least once a week, upstairs and downstairs, I used the Shark Steam Pocket Mop, until it quit heating up very quickly. Rather than fight it, I bought the Lite 'n Easy Steam Mop ... it has a longer power cord and is a bit slicker-looking. It works great, and uses the same size pads as the Pocket Mop, so I can do twice as many floors. Yeah, right!
