Abstract: An electrode cleaning apparatus for an electro-hydrodynamic (EHD) air mover device includes a cleaning scraper formed of one or more non-conductive materials. The cleaning scraper is positioned on an elongate emitter electrode and has an opening sized and shaped to receive the emitter electrode such that the cleaning scraper is slidable longitudinally along the electrode. In one embodiment, the elongate emitter electrode is implemented as a conductive edge on a mounting isolator, and the cleaning scraper is configured to engage the conductive edge and remove deposits accumulated thereon during operation.
