Single-disc scrubbing has never been easier. Advanced orbital technology is based on 1650 RPM which simulated an orbital movement with no sideforces, so everybody can operate it without training. The i-scrub 30EM is available in two versions: the Pro version with a detachable power cord and the B version is battery powered. The i-scrub 30EM is a nifty machine with a lot of power. The water tank on top ensures you can mix in your chemicals to perfection. To prevent damage to furniture and walls, we've created a rubber bumper for you to work freely!
