Hi there, Justin. I have a suggestion which may not be practical but is worth considering: Run a bare, conductive conductor inside the vacuum hose. If=20 possible, connect it to the metal pipe that you hold while using the=20 vacuum. Conductor does not need to be large, just=20 sufficiently-robust to withstand the debris that will impact it. What you describe is a common problem with central vacuum debris=20 collection for woodworking shops and similar. The central vacuum=20 system is usually quite large and moves a significant amount of=20 air. The piping for these systems is usually plastic pipe with=20 inside diameter of 4" or so. Running a single conductive conductor inside the piping and grounding=20 that conductor virtually eliminates static buildup. In your case, you don't necessarily need to drain the static to=20 ground but simply ensure that it is discharged to the same potential=20 that your body is. If you do ground it, put a 10k or so, 1W resistor between the wire=20 and the external ground. This is a very low-cost solution that may work well for you. It is=20 certainly worth trying. dwayne At 10:18 PM 3/9/2019, Justin Richards wrote: >Summary: > >I get lots of static zaps while vacuuming the carpet and hoping the list >may be able to recommend ways to reduce or preferably eliminate the zaps. > >I am considering replacing the 2 core power cord with three core and >earthing the metal pipe section of the vacuum wand.
