Construction dust is fine, abrasive and heavy in silica from concrete, masonry and tile cutting.
Why a normal vacuum makes it worse
A domestic vacuum without fine filtration passes the smallest particles straight through the exhaust and back into the air. The floor looks clean; the air is worse than before.
Why sweeping is not the answer either
Dry sweeping lifts fine dust into the air where it hangs, then settles on everything you have already cleaned.
What works
Industrial vacuums with proper filtration, top-down order so you are not re-soiling finished surfaces, and damp methods where the finish allows it.
The health side
Respirable crystalline silica is a genuine occupational hazard and there are WA workplace requirements around it. This is a reason to treat construction dust as a specialist job rather than an afterthought.
