Ever blast a PC fan with a can of "air"? Dust blows off everywhere. It
would work, even with a moderately weak compressor.

I was thinking along the lines of a thin, transparent plastic cover(s)
with "memory" of being tightly rolled. Blow the catch holding the
cover down and it rolls back to remove all the accumulated dust. Not
sure if it would survive the journey, however.

Seems like a nuke-powered rover can be made self-heating, so why the
concern over cold?
