ABSTRACT:
An anti-static dust collector includes a tank and an electrically non-conductive flexible hose, both of which are susceptible to the build-up of static electric charge. To remove such charge from the hose, the hose includes a helical wire which is connected to the grounding terminal of the electrical power plug used to supply electric power to the dust collector. Where the housing of the vacuum cleaner is electrically non-conductive, accumulation of electrostatic charge from the housing is removed by a metallic strap connected to the interior of the housing and also electrically connected to the grounding terminal of the power plug.
