In addition, since the suction resistance increases due to the rag or mop, and the suction amount of the cleaner body decreases, there are disadvantages such as a decrease in dust suction capability and an overload applied to the electric blower.

Accordingly, the applicant of the present application has proposed a suction device in which suction ports are arranged in front and rear on the bottom surface of the suction device main body and a wiping member is mounted on the rear suction port in Japanese Patent Application No. 7-104429. In this suction tool, a wiping member is provided at the rear intake port so as to be movable up and down, and when cleaning a flooring or the like, the wiping member is projected from the intake port, dust is sucked from front and rear intake ports, and a wiping member is provided. At the same time, dust is adsorbed and the operation of wiping the flooring or the like is performed at the same time. When cleaning a tatami mat, a carpet, or the like, the wiping member is housed in a rear intake port, and dust is absorbed from a front intake port so that the wiping member does not touch the surface to be cleaned.

However, in this configuration, the wiping member is simply moved up and down. Therefore, when cleaning a carpet or the like, even when the wiping member is stored in the rear air inlet, the surface to be cleaned is not cleaned. May come into contact with the wiping member, unnecessarily soiling the wiping member, or soiling the surface to be cleaned by dirt attached to the wiping member.

Then, by pulling the support 26, the engagement between the locking claw 27 and the shaft member 24 is released, and the support is replaced with a new cloth 31.

If there is no cloth-like body 31 to be replaced, the wiping member 32 with the cloth-like body 31 removed is mounted on the shaft member 24, and the wiping member 32 is positioned on the bottom side of the suction tool main body 1. Perform the wiping operation in the state of being held. When the wiping member 32 has removed the cloth-like body 31, the elastic body 30 is in contact with the surface to be cleaned, and the elastic body 30 uses a brushed body. Therefore, the surface to be cleaned can be wiped and cleaned by the elastic body 30. . Since the wiping member 31 is configured to be detachable with respect to the shaft member 24, after the surface to be cleaned is cleaned by the elastic member 30, the wiping member 32 can be removed from the shaft member 24 to wash the elastic member 30. .

When cleaning a surface to be cleaned such as a tatami mat or a carpet,
By operating the operation unit 23, the shaft member 24 is rotated, the wiping member 32 is stored in the storage unit 17, and the roller 25 is positioned on the bottom side of the suction tool main body 1. When the wiping member 32 is stored, the front and rear wheels
33 and 34 and the roller 25 are grounded to the surface to be cleaned, and the mobility of the suction tool main body 1 is improved.

Further, since the roller 25 is disposed in the vicinity of the extension of the axis of the connecting pipe 4, that is, in the portion where the most force is applied when the suction tool main body 1 is pushed forward, the movement of the suction tool main body 1 is increased. The performance is further improved.

When cleaning unnecessary tatami or carpets with the wiping member 32, the wiping member 32 is stored in the storage portion 17, so that the cloth 31 of the wiping member 32 comes into contact with the surface to be cleaned. In addition, the wiping member 32 is not unnecessarily stained, and the wiping member 32 is not stained on the carpet or the like, so that the carpet or the like is not stained.

The locking claw 27 is formed at an eccentric position of the support 26, and the short side of the locking claw 27 is configured to rotate inside the storage portion 17, so that the height of the storage portion 17 can be reduced. The narrowing of the road 8 can be prevented.
