Tonight I cleaned a Toyota dealership showroom. I scrubbed the tile with my Orbot Vibe Tile Brush. Seems it warped just sitting in my van. I guess the heat was just too much for the plastic. Wish they would make it with a metal backing. Frankly, this is bull crap to have this warp just sitting in my van. I used it anyway and it was loud as it banged against the lower shroud of the vibe.
