I did a basic mopping of Sudoroom last night (without moving furniture), and was able to remove a lot of silt dust that was everywhere. I also only used water, as my objective was to capture dust. 

There is still big particles the mopping could not pick up; yet sweeping will resolve. I also had to circulate five mop buckets because it was so dusty. It also had taken about an hour and a half. 

It would be good in the near future to have a Sudo Mop party day, with volunteers, to help move furniture back and forth, and have at least 2-3 people mopping. This would be a very effective way to bring all of the dust to an optimal minimum.

The time would be shortened with another mopped as well :-).

I'll spear head a near future day when I less busy. 

Cheers.
