I bought my Shark floor steam cleaner in August 2008 and have been happy with how well it cleans. I do agree with Jillibean's comments that the cord is too, too short. I have to unplug and replug in different areas. If it had a cord as long as a vacuum, it would be better for me. The tank size is just right. If I just do the kitchen floors, I have to pour out water. I like the reusable pads. Mine came with 2 so I can switch out and keep cleaning and then throw in the wash with my other kitchen laundry.
It uses no chemicals (I have 2 small boys and a dog so careful on chemicals), really cleans well and is good on tile and wood floors (what I have in my house). It leaves a fresh scent of steamy water, not perfumy or chemically like cleaners. It takes only 30-45 seconds to start the steam working so I plug it in, move my kitchen chairs to another room and by the time I'm done with that, I'm ready to clean. I feel that it is very light weight. Until the pad gets really damp, it is a bit harder to do the push and pull action. But after a while, it's fine. I've not been burned but I read the booklet that you need to unplug the unit, wait several minutes and then remove the pads. Otherwise, I think you could get burned.
My Shark cost $79 but I also had a 20% off coupon at Bed, Bath & Beyond. I think it was a good buy.
