CONSTITUTION:A cleaner main body 21 is provided with a motor-driven air blower 22, a rotary brush 24 for scraping up dust on the floor surface into a suction port 23, and a motor 25 for driving the rotary brush 24. To this body 21, a switch operating roller 37 for abutting on the floor surface is attached so as to turn at a prescribed angle. On a part of its switch operating roller 37, a projecting part 38 having the same axis center as the axis center of the roller 37 is provided, and also, on the body 21, changeover ON/OFF switches 44, 45 for switching the rotational direction of the motor 25 are provided so as to abut on the roller 37. As a result, the operability and the assemblability are improved.

Problems to be Solved by the Invention In such a conventional configuration, when operating the vacuum cleaner back and forth, there is a time lag between the user's back and forth operation of the handle and the back and forth operation of the vacuum cleaner. There was an issue of poor gender. In other words, when the vacuum cleaner moves from front to back, folds or moves from back to front, the vacuum cleaner moves even though the handle has already moved from front to back (''or back to front). There was a problem in that the switching of the rotation direction of the rotating brush was delayed by the distance of the elongated hole9, resulting in a time lag.

Effects of the Invention As described above, according to the present invention, when moving the main body forward, the rotating brush is rotated forward, and when moving the main body backward, it is rotated backward, so that both functions assist the operation of the main body. This makes it possible to obtain a vacuum cleaner with good operability, similar to a vacuum cleaner with a self-propelled mechanism. Since the housing and switch operation roller are in contact with the floor surface, the rotating direction of the rotating brush changes quickly in response to the movement of the main unit back and forth, which eliminates the time lag that was a problem in the past and improves operability. is obtained.
