This 20" polished steel floor burnisher is manufactured by Trusted Clean, and runs at 1,500 RPM to provide your floor with the highest shine possible. Unlike a rotary buffer, this burnisher actually runs in a straight line, forwards and backwards. It is manufactured from highly polished stainless, and chrome plated steel, providing a very professional looking machine. The flexible pad driver has a center-locking device to assure that the pad is always centered underneath the machine, providing a "vibration-free" burnishing experience. Now that's top-of-the-line service!
