When there is no human presence, if the mop becomes dirty and runs automatically, causing water or stain residue everywhere, how can it be avoided or solved?

This situation will not occur because the vacuum has already sucked away the garbage/water stains, the brush roller is designed to maintain a self-cleaning state during the cleaning process, this helps to prevent debris from accumulating on the roller and ensures that it continues to effectively clean the floor. The mop only dries the floor instead of dragging the dirt.
