To unnecessitate carrying-around a vacuum cleaning part by constituting a vacuum cleaner of a mop-like dust collecting part for adsorbing dust and an independent main body vacuum cleaner for sucking the dust.

The dust collecting part 1 is moved on a floor surface by holding a handle and dust stuck to the floor surface is adsorbed and removed. The dust collecting part 1 where dust is stuck is pressurized at the sucking port 4 of the vacuum cleaning part to suck and remove stuck dust. The cleaning part is constituted of a dust sucking port 4, a filter 5, a vacuum fan 6, a motor 7 and an evacuation port 8 and is independent of the dust collecting part 1. Thus, the vacuum cleaner is in a separated state in the case of cleaning the floor surface so that it is not required to be carried around. Then cleaning is easily executed.
