ABSTRACT:
A vacuum cleaner is disclosed. The vacuum cleaner includes a motor casing to receive a driving motor with an air outlet through which air from a dust collecting chamber flows. The vacuum cleaner includes a cleaner body with a driving chamber that receives the motor casing therein. An air discharge unit is disposed at the cleaner body through which air which flows from the motor casing of the driving motor is discharged to an outside of the driving chamber. Noise reduction is achieved by guiding and reversing a discharging direction of air discharged from the motor casing at least two times.
