I am questioning if Dyson fans are really easy to clean. Looking inside the base of the structure I see an internal fan or turbine. Won’t dust accumulate on the turbine blades and decrease efficiency over time? I don’t see how vacuuming the exterior intake vents will do anything about the dust on the turbine blades.
Or maybe I don’t understand turbines very well. And that the high speed airflow passing through the turbine prevents the accumulation of dust?
