The Porter-Cable 7800R is a Factory Reconditioned 3.4 Amps Long Reach Drywall Sander. The sander is long enough to sand 10 ft. ceilings from the ground, lightweight (8 lbs) and able to suck up the vast majority of the fine, potentially harmful dust with an attachable vacuum. The 1-1/4" vacuum hose is 13 ft. long, so a person can cover a lot of ground without having the move the vacuum. It easily sands three times faster than hand-sanding-maybe even four times faster. And the end result is a large, smooth, uniform surface.
