The U.S. Consumer Product Safety Commission is warning owners of a brand of pressure washer sold online that using it could subject them to a serious electric shock or electrocution.

Big picture view: The agency said PowRyte pressure watchers do not have an integrated immersion protection device on or new the power plug.

The device, also known as a ground-fault circuit interrupter, protects people from severe electrical shocks and have played a key role in reducing electrocutions.
