OF30Pro | Multi-Surface Planetary 30" Concrete Floor Grinder & Polisher | Variable Speed




The Onfloor 30Pro is a floor grinder, floor polisher and wood floor sander that can radically increase your diversity.  The 30Pro is a highly efficient machine equipped with Onfloor’s patented triple-belt planetary technology that provides a unique Spirograph pattern on the floor. The 30Pro is designed for multi-surface applications such as sanding wood, grinding concrete, polishing concrete and the removal of all types of coatings and adhesives. It’s light enough to sand wood yet heavy enough to grind, polish and prepare concrete at a high rate of speed. The 30Pro platform also incorporates Onfloor’s unique and patented tool attachment system. This system provides flexibility for the tools to follow the contour of the substrate and scratch it evenly. Therefore, minimizing the over grinding of high spots while consistently scratching the low spots.

The 30Pro is able to prepare more than 1500 square feet per hour of concrete per grit on single phase 208-240V power. It’s all Fast n’ Easy with Onfloor.
