A Dyson vacuum cleaner must plug into a wall outlet to receive electrical power, the same as any other manufacturer's vacuum. A break in the power cord is potentially dangerous and must be replaced if you are to continue using the vacuum cleaner. Since the plug on the power cord is moulded on, the entire power cord must be replaced. You can replace the power cord yourself, once you acquire a new plug from a hardware store or electronics shop. The procedure does not require any electrical skills, although you will need a few household tools.
