Roomba-like atmosphere filtering small bot

Don't air scrubbers do exactly this anyway, except better since they have an apparently infinite capacity? There's not much point to having a moving one, since gas physics guarantee a stationary one works just as well. And if it has a limited capacity, then it'll be worthless anyway - air siphons are surprisingly useless at de-gassing rooms, since they don't hold nearly enough gas to do it effectively.

Actually, gas physics in game ensures that stationary scrubbers aren't very effective at this. They'll empty their own square of the offending gas, causing some more to fill in from the adjacent squares and so on, reducing the concentration but they take ages to actually get rid of all the gas.

This little thing would ideally be used in conjunction with a scrubber, so you can plop one of these in a room with a scrubber (or with a scrubber outside, if you don't want to walk into a plasma fire for example) and it will go around collecting the small amounts of left over gas that would otherwise require you to go hauling your scrubber all over the room for 5 to 10 minutes to clear out.
