Mopping Walls for Dust Removal

So I'm out here on a new construction house, we're gonna be mopping the walls. If you've never seen mopping the walls or you don't know what mopping the walls is, all we're doing is just taking a mop, a dry mop, and we're gonna be knocking down all the loose dust that was created by the dry wallers, sanding this sun valley or skip trial texture. So I'm just gonna be mopping them. They're gonna be going back afterwards in vacuuming and cleaning everything and then priming with APVA primer. So if you've never heard of the term mopping the walls or you've never seen it, that's mopping your walls. We don't mop the ceilings, we just mop the walls themselves and I'm just gonna go up and down, you can kinda see it just knocking down some dust off the walls and this is what mopping your walls is.
