The Dust Deputy Ultimate is a cyclone and 9-gallon plastic dust collection kit that converts an ordinary shop vacuum into a high-efficiency cyclone vacuum. Specifically designed to work with the Festool CT shop vacuums, it functions with other brands as well and incorporates a bag hold-down feature that allows you to line the 9-gallon dust bin with a plastic bag for easy waste removal. Waste goes into this bin, rather than the shop vacuum, and you can see the material separation in the clear cyclone. The Dust Deputy Ultimate is priced at $249.
