Step One: First we use a simple non-toxic, eco-friendly cleaning solution to agitate the dirt that s ingrained into the floor (that s why mopping never removes it, allowing it to build up over time). Step Two: We then use our patented floor tool that applies heated water at just the right pre-selected cleaning pressure in the Containing Dome pre-selected at a level that precludes any damage. At the same time the water is being applied, it s also vacuum-extracted at 5 gallons per minute, leaving the surface almost completely dry. Why waste more time and effort "trying" to clean your hard surfaces the old fashion way? SureClean offers fast, effective, and affordable solutions that work on any hard surface: natural stone; travertine; brick; concrete; and stucco. We can do it all - vertical or horizontal. Our specialty is cleaning tile and grout, but we can do much more.
