Actually, I'm not sure this was the right effect. Certainly there is no 
wind to blow away the smoke and dust.  

On the other hand, dust and smoke float in air and even rise if the air 
or gases around them are hot enough. But without an athmosphere, dust 
particles kicked up will continue on ballistic trajectories. Gas will 
expand and thin out spherically. I suspect that dust and smoke on an 
asteroid will disperse faster than in quiet air.
