I was thinking....could you use maybe rice (smallest grain you could find) or maybe dry corn meal to suck up into a dyson regularly to clean out the insides of the cyclone thingies.......??????
Of course, you would have to do this before it was plugged, and make sure you had installed clean filters before doing this (and perhaps afterward too).......
just curious what the pro's out there might think about this......
by the way, both these methods work fantastically well for crystal goblets and decanters......just fantastic way to clean these things........
