The Rotobrush was designed and patented for one purpose: air duct cleaning. It is the only method that power-brushes and vacuums at the same time. Because the rotating drive cable is contained within the vacuum hose, the Rotobrush can be snaked through the air duct all the way to the plenum.

Right angle turns are routine for the Rotobrush. It brush-vacuums every contacting surface, including wrinkles and crevices of flex-duct found in most systems. When the operator manipulates the rotating brush back and forth all the way to the plenum, and again as it is being extracted, the Rotobrush breaks loose dust and residue much like you would do by hand. Its strong vacuum nozzle sucks up the debris and deposits it safely in the self-contained dust reservoir.
