The STI 20″ Swing Machine is a versatile rotary floor machine for grinding, polishing, and restoring concrete, terrazzo, and stone floors. With a 20-inch path, it covers more area per pass than a smaller machine — making it a productive choice for larger floors and restoration work, while still running the pads you need for a finished result.
Call for pricing and availability, or request a quote — you’ll talk to a real surface-prep expert, not a call center — fast answers and real recommendations.
