Two people can paint a room much faster than one. That's why we've created the Ryobi DUETPower Paint System. Two people can use power applicators from the same paint source one person can be rolling and the other cutting in around doors, windows and in corners. Just slide a pre-mixed gallon of paint into place, slide the lid down and get to work. FLUID Technology keeps fresh paint flowing back and forth between the paint source and applicators, so clogging is a non-issue. The DUET gives you beautiful results fast.
