The connection port 5 is located below the dust collection chamber 3 for disposing
The sucked dust may fall from the connection port 5 through the floor nozzle 2 to the floor surface.

In addition, the floor nozzle 2 is connected in parallel with the longitudinal direction of the main body 1 and is directly connected to the dust collecting chamber 3. However, in order to secure a required dust collecting volume as a vacuum cleaner, the dust collecting chamber 3 is required. In particular, it is not possible to reduce the size in the front-rear and left-right directions, and the front-rear dimension of the main body near the connection port 4 is inevitably increased.

The present invention solves these problems.
It is an object of the present invention to provide an inexpensive and highly usable vertical vacuum cleaner.
