In the vertical vacuum cleaner according to the first embodiment, the electric blower 2 is arranged in the vertically long cleaner body 21, and the dust collecting chamber 3 is provided in the upper portion of the body 21. The dust collection chamber 3 is shielded from the outside air by a lid 11 that can be freely opened and closed. An opening 22 is formed on the upper rear surface side of the main body 21, and an elbow-shaped connecting member 23 having one end facing the opening 22 and the other end facing the dust collection chamber 3 is installed inside the opening 22. The upper end of the bellows-shaped hose 7 which is a suction air passage inserted through the opening 22 is airtightly coupled to the end of the opening 22 on the side thereof. Therefore, the end of the connecting member 23 on the opening 22 side constitutes the suction port 4 on the main body side. The other end of the hose 7 extends rearward of the main body and then faces downward, and a connection pipe 13 fixed to the lower end of the hose 7 has an upper end of a cylindrical connection port 12 integrated in a lower portion of the main body surface and extending in an obliquely vertical direction. It is detachably inserted into. At the lower end of the connection port 12, a connection pipe 15 on the suction tool 14 side that can be turned up and down is detachably inserted.
That is, the hose 7 is installed in a bare state between the main body 21 and the suction tool 14.
