Abstract: A vacuum cleaner including a suction motor assembly having an impeller configured to generate vacuum pressure, a motor driving the impeller, and a motor shroud including a conductive material and at least partially covering the impeller. The vacuum cleaner also includes a battery pack configured to selectively power the motor and having a positive terminal and a negative terminal, a ground wire electrically connecting the motor to the negative terminal of the battery pack, and an electrostatic discharge wire electrically connecting the conductive material of the motor shroud to the ground wire such that electrostatic charge generated on the motor shroud is discharged through the electrostatic discharge wire and dissipated through the negative terminal of the battery pack.
