The U-SAND is a revolutionary four-pad sander that utilizes random orbit technology, which allows for easy sanding of wood flooring. Unlike other commercial sanders, the U-SAND will not leave unsightly swirl marks and drastically reduce the risk of damaging a floor. Operators of this machine will notice a relatively dust free environment while easily maneuvering with or across the grain. Even more impressive is that this one machine can do the job of a conventional sander, edger, and buffer!
