Here is a system that uses compressed gas to perform excavation and cleaning tasks. POCCET is pneumatic system for mini space rovers. It weighs less than 300 grams and can be used not only on the moon but comets, asteroids, and Mars.
As the above video shows, this dust removal tool can be easily mounted to JPL’s PUFFER platform. POCCET can trench through regolith to expose subsurface lunar ice. Honeybee Robotics is behind this idea.
