Thinking about robots whose internal cooling systems produce condensation, which naturally pools in the lowest point of their torso, so they have a collection tank there that has to be emptied periodically before it starts backing up into their other components. Their systems are set up to warn when the tank is approaching full, but if it's inconvenient to empty it immediately they can dismiss the pop-up notification.
Thinking about robots who haven't had a chance to empty their tank all day, or are too busy to, or happen to be somewhere they can't just dump wastewater, so they dismiss the pop-ups over and over again. 75%, 85%, 90%, 95%, 99%...
Thinking about robots who literally slosh as they move because there's so much water built up inside them, whose performance is starting to lag because they can't move as quickly with their gears waterlogged like this, who keep leaking out of their hip joints and hoping their human companions just think it's normal external condensation and not waste.
Thinking about robots who have gotten the 100% Warning! Automatic System Flush in 5... 4... 3... multiple times already, and they press Notify Me Later but it keeps coming back, in shorter and shorter intervals, until it only takes a few seconds of distraction before it's too late and the system takes over...
Thinking about robots who are drenching their legs and and the floor and everyone in the splash zone, and soak their hands too as they frantically try to manually close the release valve, but the water pressure is too strong to be stopped. They try to at least stop once the tank is out of the red zone, but their system ignores their commands until their tank is completely drained to a pleasant green 0%.
Thinking about robots miserably apologizing to their companions and saying "I tried to keep it inside but there was so much... It wouldn't stop, I'm sorry." Their companions reassure them that it's not a big deal, honestly it's just water, it's not gonna hurt anything, but the robot is so ashamed of their inability to maintain their own body that they barely listen.
Or maybe their companions aren't so understanding, and lecture them about letting it build up so much, risking a system failure, honestly don't you read your own pop-ups? It never should have gotten to this point. And the robot wants to protest they they would have emptied their tank if they could, but there was no time, and who's the one who set this punishing schedule anyway? The humans got to take bathroom breaks but the robot had to stand guard even while they were filling and filling... But they know there's no point.
Thinking about robots who have to hose themselves down once they get back to the maintenance bay and know that all the other robots will know exactly what happened. Because they've all dismissed that pop-up long after it reached critical, but most of them managed to make it somewhere private to release.
