As is clear from the above description, according to the present invention, since the brush body of the cleaner is provided with the variable length brush body, first, the flocked portion of the brush body is shortened. This increases the rigidity of the device, and makes it possible to strongly suck the adhered dust while detaching it from the cleaning surface. In addition, the drawback of the conventional cleaner, in which the cleaning surface is in close contact with the suction hole of the nozzle due to a strong suction force and hinders the work efficiency, is prevented by the effect of the rigidity of the flocking portion, so that cleaning can be performed efficiently and completely. It was possible to expect a remarkable effect.

Further, according to the present invention, since the length of the flocked portion of the brush body can be adjusted and maintained at an appropriate length, an easy-to-use feeling and a cleaning effect can be obtained according to the state of the cleaning surface. Further, by extending the flocked portion, it can be appropriately used for cleaning, for example, gaps between adjacent keys of a keyboard, corners of sills such as shutters, and small gaps of furniture and kitchens as described above. That effect can be expected.
