Hello i had this issue as well. It was not the brushes , under the black cover under the bottom of the base there is a cooling fan blade made of plastic,  the nut holding this on has unscrewed itself and the dust being created is the fan blade rubbing on the plastic cover  because it has dropped lower. All you need to do is tighten the blade nut and put back the cover and all is fixed.
