And how do you refill a positive pressure system inside the machine if there is no external atmosphere available that you can just suck in and compress? Do you want to add constant gas resupply from Earth to one of the cost factors?

If you are building stuff on the moon you're for sure mining the 600 billion kilograms of water ice already discovered and can make all the gas you need!

At a concentration of 1000 parts per million in the soil you'd have to move and kick up a lot more destructive regolith dust than you'd ever hope to get enough gas out of it to protect the excavator from that dust. Not to mention that you're just utterly wasting the most precious resource of all on the Moon.

You're thinkin of the water in the actual moon dust. I was referencing the recently found actual water ice found at the poles. You didn't follow any of that and the proposed Chinese and US moonbase because of it?
