double insulated products do not require a ground

There are at least three possible reasons.
1. the plug is from an old electrical cord. Not all that long ago (50's and 60's) most outlets and cords were plain two pronged versions.
2. A lot of newer devices are internally grounded and double insulated. If you look at the cord you'll notice that the blade on one side is slightly wider than the other so that it should only fit one way into the outlet (wide side on the left.)
3. Some lamps and appliances just don't run many watts and supposedly don't need the grounding.

If a circuit is installed correctly, you will have two wires going to the grounding strip in the breaker box anyway.. In anticipation that grabbing hold of an electric tool that is connected to a two prong cord, they will use what they call double insulation which is just a way to keep from getting the devil shocked out of you.
Old Black and Decker tools were great for shocking the user and I would think the same thing was with all tools when they were all made of metal.
The thing you should be looking for even in UL appliances or UL approved tools is tht the power cord is the right cord for that tool. I do not know how vacuum cleaners to away with it, but invariably in moving the cord to another spot, when I touch the cord, it is hot, or really warm.

two pronged electrical plugs are double insulated. All this really means is there is no chance for you to touch the metal parts of the unit and ground at the same time. All plastic case as an example. Three pronged plugs have the required two wires to make the unit run, plus another fastened to the metal parts.

Yes some are what the manufactures call double insulated, (I think it's just cheeper) go for the grounded plug. Most homes today have grounded receptials. It is much safer. Some people still cut the grounded pole off, that is very unsafe, DO NOT cut the grounded pole off.

Some items are double insulated inside their case and do not require the grounding wire, I.E. blenders, mixxers, drills, curling irons. Most items do require the grounding wire. This prevents electrocution.

Tools and appliances that have two prongs are double insulated to protect you.
