Sufficient pressure on water hose.
In almost every robot room there is a water sprayer and there is a place where a brush, cloth, roll of soft paper, cleaning agent such as antikal and other frequently used cleaning material.
If it’s close by and works well, it’s more likely to be used.
Very often there is only little pressure on the water hose or is too short, so when you rinse it you only clean it half, or half far.
“It doesn’t matter, I’ll go over it every now and then with the pressure washer”…
Nevertheless, it works very pleasantly if there is sufficient pressure, because at the intervals, cleaning quickly, you keep track of it much better. And when you rinse the VMS cups and frame (daily?) with a car wash brush, it is nice if enough water comes out!
Perhaps the high-pressure sprayer is needed just a little less often, which is good for the printed circuit boards and other vulnerable parts…
