    Clean up duct:

    Use the agitation brush to scour up the dust inside the dust. Collect this dust using your vacuum cleaner. The hose attachment of your vacuum is the most effective tool for it. Give close attention to the joints and corners because most of the dust accumulates there. Go as far as you can with the length of your vacuum cleaner.  However, you might not be able to reach all the length of the duct. If you are using hose sections to increase the length, use  a tape to secure them fully so that they do not come off inside the duct.
