PROBLEM TO BE SOLVED: To provide a self-propelled ion emission device capable of efficient air cleaning.SOLUTION: A self-propelled vacuum cleaner 1 with a self-propelled ion emission device applied thereto includes an ion detection unit 56 that detects the amount of ions around the cleaner during self-propelling, an ion determination unit 522, and an ion emission controller 523 that controls an ion generator 62 and a blowing device 61 to emit an air flow containing ions from an exhaust port when the ion determination unit 522 determines that an output value detected by the ion detection unit 56 is a set value or less. |
