I know that the Velcro on the steam cleaner is supposed to stick to the pads. And it does to a certain extent. But the pads do come off when I’m using it some of the times. If they were fitted slightly at the corners (instead of being a flat sheet), it would make them so much better. They wouldn’t have to be super tight - just something to come up over the device a bit. That being said, I do love how easy this system makes it to keep my kitchen floors clean!
