The Ultimate Dust Deputy® is designed to maintain a continuous grounding path from tool to the grounding of the vacuum's inlet when used with grounding tool hoses. All of the Oneida Ultimate Dust Deputy components are made with static conductive or static dissipative materials. In our testing, the Ultimate Dust Deputy does not add any impedance to the grounding path and maintains the pathway to earth ground on vacuums with a grounded inlet.
We also employed two 3rd party engineering firms to provide detailed and unbiased reports on the static resistance of the Ultimate Dust Deputy. The table below shows the resistance levels that were measured from the end of the green Vacuum hose to the end of the Vacuum's earth ground prong which inserts into your outlet. Though the findings from each firm differ slightly, they both conclusively show that the Ultimate Dust Deputy falls in the conductive range of static resistance. Full report data can be downloaded using the links in the table below.

How does this apply to older (pre-2014) Ultimate Dust Deputy units?
Our current Ultimate Dust Deputy® model features a black static dissipative cyclone that preserves the static loop right out of the box. Our previous models however, did require the use of foil tape to maintain the electrical ground on the Festool unit. Further information on these older models (which may still be stocked third-party vendors) can be found within their included owner's manuals here.
