Assess Paint Level and Prepare to Reload

What happens here

After a period of painting, the user observes the paint coverage on the wall and states that the internal reservoir of the paint delivery system is nearly depleted. He remarks that "almost half" of the paint has been used and that it took "one whole thing to actually load it up" previously. This observation signifies that the system needs to be refilled soon for continued painting. He then verbalizes the intention to "load it up again" and starts to lower the roller, preparing for the refilling process, which is not shown in this video segment.

Goal: Recognize the need to refill the paint delivery system and prepare for the refilling process.
