The invention discloses a direct-current blower-vacuum. The blower-vacuum comprises a main case, a drive motor, a direct-current power supply, a collecting device and an electrostatic discharge unit, wherein the main case is provided with an air outlet, the drive motor is disposed in the main case, the direct-current power supply is electrically connected with the drive motor, the collecting device is connected with the air outlet, and the electrostatic discharge unit is electrically connected with the drive motor and extends to the air outlet or the inside of the collecting device. According to the blower-vacuum, the electrostatic discharge unit is arranged in the blower, so that gathering of static electricity in the direct-current blower-vacuum can be avoided, electrostatic shocks to users or damage to electronic components inside the blower-vacuum can be further prevented.
