ことにもなる。It is also practiced to neglect the troublesome replacement operation and to slide the floor brush 1 still attached to the extension pipe back and forth while pressing it strongly against the floor surface to forcefully suck in the dust in the corner. . In this case, the repeated strong sliding motion of the main body 2 may cause the floor brush 1 to be worn or damaged. In addition, turbulent airflow is generated by the reciprocating motion of the floor brush 1 and back and forth, and dust and dust are floated up on the floor surface. The dust or dust that is lifted up will enter the inside of the storage portion 10a through the gap G of the floor sensor 10. As a result, the dust that has entered inside adheres to the bearing of the swing shaft 16 and the surface of the ball 18, and a frictional force is generated at the contact portion, which makes movement unsmooth and causes a malfunction in the detection of the floor surface. Also becomes.
