Since the air-out filter device is restrained by the shape of the motor, it has a small sectional area, poor filtering effect, and is required to be replaced frequently. Moreover, since the airflow first flows through the motor and then is discharged to the outside through the air-out filter device, the air-out passage is not smooth and is relatively short, and the noise reduction effect thereof is not significant. Moreover, since the motor is far from the battery, the wiring thereof is complicated. Since the center of gravity of the conventional vacuum cleaner is at the front part in usage, it is laborious to use the vacuum cleaner. Besides, the handle angle thereof does not conform to usage habits.

The second machine body 24 includes a rear receiving part 240 which accommodates the battery 40, and a rear handle part 242 which extends downward from the rear accommodating part 240. The handle 26 is provided with an airflow passage 260 via which the front accommodating part 220 is in communication with the filter part 28. The length of the airflow passage 260 is at least greater than ⅓ of the height of the cyclone dust separator 10 but less than the height of the cyclone dust separator 10. The handle 26 is formed by at least parts of the first machine body 22 and the second machine body 24, that is, the front handle part 222 and the rear handle part 242 are engaged to form the handle, or the handle 26 may also be formed only by the front accommodating part 220 of the first machine body 22 extending downward. Preferably, an extending direction of the handle 26 intersects with the axial direction of the motor 30 at an obtuse angle so as to conform to ergonomics. The handle 26 connects the first machine body 22 and the filter part 28. The air flow passage 260 may be provided with a sound attenuation material in order to reduce noise. A bottom end of the filter part 28, a bottom end of the cyclone dust separator 10 and a bottom end of the cyclone 14 are located on the same horizontal plane. The filter part 28 includes a filter chamber 280 therein, a detachable air-out filter device 60 accommodated in the filter chamber 280, and multiple air outlets 282 in communication with the filter chamber 280 and located downstream of the detachable air-out filter device 60.
