Out of all the Dysons I have owned, only one died of plaster dust. The DC05. I have vacuumed up plater with a DC04, DC14, DC24, DC25, DC08, DC05 and DC01. All survived except from the 05.
With the dc08, it had been used for plaster dust, saw dust, nails, screws etc and been bashed around with NOO filter washes. I got annoyed with the filter getting dusty, so I took the filter out and vacuumed. The post motor filter captured ALOT of the plaster dust. The motor never died. Then the machine got tilted up when I pulled the hose, the bin was upside down, the dust went through the shroud, through cyclones and into the motor. Still never died. Then I left it in the garden for 4 months. In snow and rain it just sat there. Then I took it home and tried it. The only thing broken was the switch. I out in another one and turned it on. The motor still worked as expected from a dyson...
