It is hard to say for sure. I think a wet/dry vacuum would be safe so long as enough water is on the floor so you are vacuuming a liquid rather than slightly damp materials. If it dries from the air flow, some dust may pass through the filter. The finer particles that pass through vacuum filters are the particles that are also too fine to cough up and expel from the lungs. If the filter gets dry, I would wash the clay out of the filter prior to the next use. Wet mopping is an option if nothing else is practical.
