Some of the janitor's animations are very messed up, like this one where he mops, he floats above the ground, his hand aren't actually holding the mop, and the mop brushes look odd, also the water droplets don't even hit the ground, they stop mid air. Along with this, the janitor and doors do not mix well, he's constantly stuck on them because he tried to close the doors while walking through them at the same time.
