Apply Paint to Wall Sections

What happens here

With the Smart Roller primed, the painter begins applying paint to the textured wall in the hallway. He uses smooth, vertical strokes, moving the roller steadily up and down the wall. As the roller cover begins to run low on paint, the painter periodically clicks the plunger on the handle of the Smart Roller. This action feeds more paint directly from the internal reservoir to the roller cover, allowing for continuous painting without needing to stop and dip the roller into a paint tray.

Goal: Achieve even and consistent paint coverage on the wall.
