I would separate the issues, vacuum cleaners are famous for electrically charging dust up to quite high voltages.

  I should clarify that the reports indicated that the shock originated from the hand touching the handle.

    I guess I should go further: some vacuum cleaners have to have a ground connection in the hose, to try to discharge the dust. If they removed it for unrelated reasons, they probably lowered the overall quality of the product overall.

      To Shark's defense, I haven't seen too many non-commercial/consumer vacuums with grounded plugs.

        That said, they (consumer vacuums) almost all have enclosures made entirely of plastic.
