We got ours about a week ago and spent this past weekend scrubbing our dining room/kitchen floors- self-stick tiles. Awesome job, only took about 2 hrs of slow careful scrubbing, the machine does ALL the work, you only have to move it back and forth and mop up. Should've invested in this a long time ago, sure helped make our floors shine!
