PROBLEM TO BE SOLVED: To provide an electric cleaner in which a sufficient air discharge path length is secured to allow a particularly large hissing airflow noise generated when a large volume of air concentrically passes through a narrow and short air path to be absorbed, and as a result, the quietness of an electric cleaner is improved. SOLUTION: The drive sound of an electric blower 51 is insulated by covering the electric blower 51 with a first electric blower cover 52 and covering the first electric blower cover 52 with a second electric blower cover 53. The air discharged from the electric blower 51 is discharged from an air discharge opening 49 after passing through the first electric blower cover 52, the second electric blower cover 53, and a discharge air path chamber 35.
