Boundary Strips work well on their own but due to the way they are packaged they come in a roll with that they refer to wanting to roll again, the supplied glue is not strong enough to stop them from rolling, but at least it's not something that will damage my porcelain tiles, i will try to find an alternative glue and Using weight to hold them in place, hope this helps. Anyway, I love that it's an option so I don't have to babysit to keep the vacuum from getting tangled in the cords.
