Tired of scrubbing your tile grout on your hands and knees?   Know why those other floor "cleaners" don't work?  It is because they are build cheap and built light.   We built the Prolux Core to be heavy (yes we did that on purpose) and geared slow so it can get down and clean the toughest stains.   Not to worry we added large rubber wheels so it feels lightweight and easy to use.   Looking for a floor cleaner, scrubber, buffer, sander that actually you know works?   Looking for something built QUALITY and USA engineered to last decades?    Consider the Prolux Core 13 inch for home and office use (check out our 15 inch model for industrial use).
