Next, the operation and operation of the vacuum cleaner according to the present invention configured as described above will be described. When cleaning a wide area of the floor, the end 34 of the handle 30 is inserted into the handle fixed storage section 40 from above. At this time,
The inclined surface 36 provided at the distal end of the handle 30 moves the fixing portion 44 of the handle fixing tool 41 toward the rear surface of the cleaner body 2 against the compression spring 45, and at the same time, moves the vertical movement receiving portion 15.
To move the wheel support member 12 downward. As a result, the wheel 16 protrudes downward from the wheel support 11. Then, the fixing portion 44 of the handle fixing tool 41 is fitted into the fixing hole 35 of the handle 30 by the urging force of the compression spring 45, and its movement is stopped, and the handle 30 is fixed to the cleaner body 2. At this time, the grip portion 32 of the handle 30
Is located behind and above the cleaner body 2.

In this state, if the user holds the grip portion 32 of the handle 30 and operates without bending down, the wheel 1
6, the gravity W of the cleaner body 2 moves toward the floor suction device 8 by the angle θ, so that the floor suction device 8 comes into contact with the floor surface while pressing the floor surface, thereby increasing the suction performance. You can run and clean easily.

Also, the handle fixed storage portion 40 is
And a part of the operating force of the handle 30 mounted above the rear part of the cleaner main body 2 reliably acts on the suction port 3 and the floor suction tool 8 Adhesion with the floor surface can be maintained. By the way, if the handle fixed storage part 40 is provided behind the wheel 16, not only the operation force of the handle 30 is not transmitted to the wheel 16, but also the suction port of the cleaner body 2 using the wheel 16 as a fulcrum during use. The third side is easily lifted, and the suction performance tends to be reduced.

Next, when cleaning a narrow area of the floor surface, furniture, a desk, or the like, the wheels 16 and the handle 30 collide with the corners and become obstructive and lack a small turning property. It is desirable that the handle 30 be removed. Therefore, first, the rotary operation body 25 is rotated to push the pressing portion 2.
The short side h of 7 is positioned below (state in FIG. 2). Next, the handle fixing tool 41 is pulled outward (in the direction of the arrow).
As a result, the fixing portion 44 is disengaged from the fixing hole 35 of the handle 30 and the lock is released, and the handle 30 is in a free state and pushed up by the compression spring 21, so that the handle 30 is pulled out from the handle fixing storage portion 40. At this time, the wheel supporting member 12 is raised by the urging force of the compression spring 21, and the vertical movement receiving portion 15 comes into contact with the pressing portion 27 of the rotary operation body 25 and stops, and as shown in FIG. It is housed in the wheel support 11. Thus, it is possible to easily carry out cleaning by holding the handle 5 even in a narrow place.

When it is desired to perform cleaning while running the cleaner main body 2 with the wheels 16 out, the rotary operating body 25 is rotated to position the long diameter side L of the pressing portion 27 downward. As a result, the pressing portion 27 presses down the vertical movement receiving portion 15 to lower the wheel support member 12 and cause the wheel 16 to protrude. Thereby, cleaning can be performed while the cleaner body 2 is running while holding the handle 5.
