PROBLEM TO BE SOLVED: To provide an electric cleaner which is hardly reduced in its sucking power even it has sucked dust while retaining a high sucking work rate. SOLUTION: A dust collecting case 5 for introducing the air containing the dust sucked by an electric blower 21 has a cylindrical shape and has a sucking port 6 for introducing the air containing the dust in the tangential direction and a dust storage part 24 on the other end side of the sucking port 6. A dust eliminating filter 27 in the dust collecting case 5 is arranged in the wind passage 29a with which the dust collecting case 5 and the electric blower 21 communicate. By a swirling air flown in the dust collecting case 5, therefore, the dust is continuously swirled in the dust collecting case 5. The dust is separated from the face of the dust eliminating filter 27 even in case the dust sticks to the dust eliminating filter 27; thereby, an intake air passage is retained at all times, and the electric cleaner prevents the reduction of a sucking air volume and has an excellent performance to maintain the sucking power.
