For multi-purpose cleaning & restoration. The ROS 17 is a multifunctional orbital floor machine. The orbital technology allows you to clean/restore every floor surface. The ROS 17 combines traditional rotary scrubbing with orbital oscillation technology in one machine. The rotary motion spins at 80 RPM and the micro orbit oscillation is 1,725 orbits per minute. This combination of the two technologies increases performance, efficiency and productivity.
