ALL electrical appliances or devices should be grounded !
Electrical systems must be grounded for the devices to function. The flow of electrons that drive them are attracted to the opposite pole of the battery and will not go through an electrical device that doesn't allow them to get to that pole.
The electrical cleaning equipment should be grounded. This grounding is what protects the operator from a serious shock should the the cleaning equipment have an electrical fault occur.

Yes, switches should be grounded for electrical safety to prevent the risk of electric shock and ensure proper functioning of the electrical system.
yes the device must be grounded per NEC code. if the juncrion box is metal you must also sufficiently ground the box using a ground screw or clip. the ground box should be uninterrupted if the device is removed. (the device screws mounted to the box is not a suitable grounding means.
All metal parts of an electrical installation should be grounded. The would include outside light posts.
To receive a shock from electrical devices you have to become part of the electrical circuit. Most electrical devices come in two categories. One, the device is grounded and the other is the device is double insulated.The grounded devices have their metallic frames grounded. On a short circuit fault this will trip the breaker and isolate the device's fault before you have a chance to ground out the device by touching it.The double insulated device has two covers that protect the user from shock. The double insulation type of protection is usually used on hand held power tools.
Yes, the electrical appliance is compatible with a grounded 3 prong outlet.

If the wire is carrying an electrical current, and if the current has enough voltage, the current can leave the wire and pass through your body. This is painful, and can causes burns or death.
OSHA does not provide a specific definition of "grounded." You should use the commonly accepted definition in the electrical industry. That is, a conductor that has a secure conductive path to ground, or "earth" as the term is used in the UK
