Why is a company like Bauer allowed to sell Wet/Dry vacuums without the three prong plug for safety? I thought that all electrical appliances designed for outdoor and wet area use should have a third prong ground on the plug and be connected to a ground fault circuit interrupter (GFCI) receptacle!

7There is a safety concept called "double insulation." Double insulated appliances do not need the GND wire. NOTE: GFCI outlets provide meaningful protection regardless of whether the attached device has a GND wire or not. The name of the manufacturer has no bearing on it. So perhaps you could remove "Bauer" from the question title. – user57037 Aug 01 '22 at 05:56

Depends on legislation but in most parts of the world you are not required to have that so plain old double insulated appliances are used. – winny Aug 01 '22 at 07:44

Very interesting question that I had myself a few weeks ago! – AJ_Smoothie Aug 01 '22 at 13:51

The ground receptacle is only required when the outside of the appliance is metal.
When it is plastic and sufficient measures have been taken to make the device safe it is no longer required. See class II.
Ground is not required for the GFCI to work, if you throw your class II corded drill into a pool the GFCI will trip.
