The front portion of 17 is opened, the roller 26 comes into contact with the wall surface W, and a space is maintained between the bulging portion 25 and the wall surface W.

In this state, the rotating brush 18 can be brought close to the wall surface W, and dust near the wall can be removed to the vicinity of the wall surface W. Moreover, coupled with the suction of air from the front side of the floor suction tool 6 through the gap formed between the bulging portion 25 and the wall surface W by the pair of rollers 26, the dust on the wall surface W is further collected. It can be efficiently removed to the vicinity.
And in the state which pressed the front surface of the suction tool 6 for floors against the wall surface W, the suction tool 6 for floors is moved to a horizontal direction, and the edge of a wall is cleaned. At that time, since the raised cloth 22 and the roller 26 abut against the wall surface W, the floor suction tool 6 can be moved in the lateral direction with good operability.

When the floor suction tool 6 is moved in the lateral direction with the front surface of the floor suction tool 6 pressed against the wall surface W, the grip portion 7 and the handle portion formed on the proximal side connection pipe 4 at the tip of the hose 2. 11 can be gripped by hands and moved laterally with both hands, and the lateral operability can be further improved.
Next, an operation for cleaning a gap between a wall surface and furniture or between furniture and furniture will be described. The gripping part 7 and the handle part 11 of the hand side connection pipe 4 are each gripped by hand and rotated so as to be turned upside down so that the handle part 11 is positioned upward.

  As shown in FIGS. 1, 3, and 4, the case where the proximal side connecting pipe 4 is rotated leftward (counterclockwise) as viewed from the user will be described as an example. As shown in FIG. 4, when the proximal side connecting pipe 4 is rotated about 90 ° counterclockwise (counterclockwise), the extension pipe 5 is also rotated with the rotation of the proximal side connecting pipe 4, and the first rotating pipe 15 is rotated. Rotate about 90 ° to the left. When the first rotating tube 15 rotates, the second rotating tube 16 rotates, and accordingly, as shown in FIG. 4, the main body case 14 rotates counterclockwise in plan view.

  From this state, when the proximal side connecting pipe 4 is further rotated leftward (counterclockwise), the rear portion of the main body case 14 is lifted upward with the front end portion (the cover body 23 side) as a fulcrum. In the state where the hand side connecting pipe 4 is rotated by 180 °, as shown in FIGS. 3 and 11 to 13, the cover body 23 is opened, and the front side of the suction port 17 of the main body case 14 is opposed to the floor surface. Erect posture (upright posture). In this state, as shown in FIG. 12, the longitudinal direction of the main body case 14 extends along the extending direction of the second rotary tube 16, and the first rotary tube 15 is moved from the main body case 14 by the holding means. The rotating position is held.

  In this state, the floor suction tool 6 is inserted into the gap between the wall surface and the furniture, and the gap between the wall surface and the furniture is cleaned by holding the handle 11 and moving the floor suction tool 6 in the front-rear direction. To do. Since the first rotating tube 15 is held by the holding means in a state along the longitudinal direction of the main body case 14 with respect to the main body case 14, the first rotating tube 15 even if the floor suction tool 6 is moved in the front-rear direction. The body case 14 does not rotate with respect to 15, and the operability is not impaired.

  In this state, the raised cloth 22 and the roller 26 are in contact with the floor surface, improving the mobility of the floor suction tool 6 and preventing the floor surface from being damaged. Since the cover body 23 rotates and the air inlet 17 opens on the front side of the floor suction tool 6 facing the floor surface, dust or the like in the gap between the wall surface and the furniture can be efficiently sucked. In addition, since the hand side connecting pipe 4 is formed to be rotatable with respect to the hose 2, the hand side connecting pipe 4 is prevented from being twisted even if the hand side connecting pipe 4 is rotated about 180 ° from the normal use state. There is no loss of selfishness.

Further, when cleaning a high place or the like, with the floor suction tool 6 removed, the gripping part 7 and the handle part 11 can be gripped and the extension pipe 5 can be supported with both hands. The operation can be performed in a stable state, and the operability can be improved.
In the above embodiment, the handle portion 11 formed separately from the proximal side connecting tube 4 is fixed to the proximal side connecting tube 4 with screws or the like, but the handle portion 11 is integrally formed with the proximal side connecting tube 4. Also good.
