Finally a brush that really gets through grout and textured surfaces! I have Armstrong tile in the kitchen and hallway. very durable cleaning material - very durable but textured so it always looked dirty. I tried several brushes like the orange one but it didn't clean the tiles or the grout. As soon as I switched on the Oreck with this blue brush, I immediately saw dirt coming off the tiles and grout. It should also be noted that I use a peroxide based cleaner. Very happy with this purchase!
