None of the debris is on the sensors. There is some small amount of dust on a window, and it shows up twice as much due due to image processing performing bias subtraction.
The sensors are in a cryostat, and the effective size you of what you might thing as “dust” in these pictures would be quite large if they had been on the sensors (several mm)

Single human hairs can also be visible in photos.

Not at the distance and resolution of a photo like this one:

See the orangish lines between the sensors.
What is however kind of surprising to me is the amount of hot pixels and also dust / debris on the sensors. You’d think that as expensive and fragile as they claim the sensor array is, they’d keep the environment cleaner. Example: https://www.dropbox.com/s/rhldlwyqzuvbf2o/2020-09-13%2007.36...
I also question the “five human hairs” wide gap between the sensor pods given that the gaps are clearly visible in the press photos of the sensor array.
