The two problems with using a mobile unit inside a workshop are the same problems as a standard VAC. Exhaust airflow blowing settled fine dust into the air, for a larger workshop like the one pictured in your photo, maybe not such a problem but in a smaller wood working shed it can be a big problem, even if you can't see it. Problem 2 is the finer particles that go right through the filter and can't be captured by the small cyclone.
