On the floor surface F, the T-shaped pipe joint 16 and the pair of blowers are covered by the lid body 20 that covers from above. A space is formed in which the side surfaces are closed to the pulling pipes 17 and 17 and the upper surface is closed to the lid 20. Therefore, minute dust is not trapped in the space and does not fly up.

[0041]   The dust blown to the central portion passes through the position as the truck 11 travels. Is sucked and removed by the suction port 13.

[0042]   Thus, the width W2 wider than the width W1 of the suction port 13 can be cleaned.

[0043]   By the way, the pair of blow-off pipes 17, 17 are located in front of the suction port 13. Therefore, when cleaning a wall or the like, the suction port 13 is blocked by the blow-off pipe 17 so as not to cover the wall. It may not be possible to reach it with, but in this case both blows in a substantially horizontal state. The pulling pipes 17 and 17 and the lid 20 are turned upward by a turning means so that they are substantially vertical. After standing up, hold the pipe hook 29 on the conduit 18 and keep it in the standing up state (See FIG. 2).

[0044]   By keeping both blower pipes 17 and 17 and the lid 20 in the upright state, The suction pipe 13 can reach the wall without disturbing the pulling pipe 17, The part can be cleaned.

[0045]   In the above embodiment, the pair of blow-off pipes 17 and 17 are arranged in a V shape. However, the present invention is not limited to this, and even if it is arranged parallel to the outside of the width of the suction port 13, the center of the dust is similarly It is possible to get the effect of blowing to the part, and it is also possible to sweep the robot using a self-propelled trolley. Not only when applied to a vacuum cleaner, but also when applied to any suction type vacuum cleaner. Wear. Further, the pipe hook 29 is provided not on the lid 20 but on the blowing pipe 17. Therefore, even when the lid 20 is not attached, the pair of blow-up pipes 17, 1 7 can be raised and held upwards.
