Vacuum cleaners are also suggested.

In this vacuum cleaner, the opening frame provided at one end of the dust collection bag is held at an angle opposite to the slanted suction port, so that the dust collection bag can be placed inside the dust collection chamber of the main body of the vacuum cleaner. Although it is designed to be worn, the vacuum cleaner body is generally shaped like a rectangular parallelepiped box.
Since the dust bag also has a substantially rectangular parallelepiped shape, a space is inevitably created in front of the dust bag on the lower side inside the dust collection chamber. And this space becomes a half-finished and wasteful space. Therefore, it is conceivable to form the dust collection bag itself into a shape that includes the above-mentioned space, but since little wind flows through this space, the dust collection capacity will not be improved much.

In addition, in the vacuum cleaner described in the above publication, the lid is installed at an angle on the front side of the vacuum cleaner body, so it becomes larger in the front and back direction, making it easier to cross over thresholds etc. when moving the vacuum cleaner body. There are some issues that will no longer be addressed.

In addition, in the vacuum cleaner shown in FIGS. 3 and 4, a handle 1 for transportation is provided on the front side of the vacuum cleaner body 1, 8.
However, since the handles 13 and 14 protrude in this way, the vacuum cleaner bodies 1 and 8 become larger and the handles 13 and 14 are provided in a protruding manner, respectively, when the cleaner bodies 1 and 8 are running. 14 collides with furniture, etc., which impairs smooth running.

(Problems to be Solved by the Invention) As mentioned above, in conventional vacuum cleaners, the handle protrudes from the front side of the vacuum cleaner body, so the handle gets in the way and becomes large. Vacuum cleaners with slanted mouths have the problem of creating wasted dead space in the dust collection chamber.
