First coupling portions 914, 1210 disposed to contact the hollow portions 913, 1130 formed by penetrating between the first surfaces 911, 1110 and second surfaces 912, 1120 of the cleaning cloth 91, 1100. );
Second coupling parts 923 and 1220, which are coupled to the first coupling parts 914 and 1210 at one end and include cleaner coupling parts 921 and 1222 that protrude upward from the second surfaces 912 and 1120. Contains,
The vacuum cleaner coupling portions (921, 1222) are a coupling structure having a shape that can be fastened to the predetermined portion (143) of the cleaners (1, 2). According to clause 9,
At least one of the first coupling portions 914 and 1210 and the second coupling portions 923 and 1220,
A coupling structure in which the surface facing the cleaning surface includes the same material as the cleaning cloth (91; 1100). According to clause 9,
The vacuum cleaner coupling portions 921 and 1222 are,
A coupling structure that has a cylindrical shape and protrudes and extends upward from the second surface (912, 1120), and a shape that can be coupled to the predetermined portion (143) of the cleaner includes a thread formed on the outer peripheral surface of the cylindrical shape. According to clause 9,
The vacuum cleaner coupling portions 921 and 1222 are,
It has a cylindrical shape and protrudes and extends upward from the second surface (912, 1120),
A coupling structure in which a shape that can be coupled to the predetermined portion 143 of the vacuum cleaner includes a protrusion or groove formed on an outer circumferential surface of the cylindrical shape. According to clause 9,
The second coupling portion 923 is,
A coupling structure disposed so as not to protrude downward from the first surface 911 through the hollow portion 913. According to clause 9,
The first coupling portion 1210 is disposed to contact the hollow portion 1130 on the first surface 1110 side,
The second coupling portion 1220 is disposed to contact the second surface 1120 and is coupled to the first coupling portion 1210. A method of coupling the cleaning cloth (91, 1100) to the predetermined portion (143) of the vacuum cleaner (1, 2) using a coupling structure,
The vacuum cleaner is
It is provided with a motor and a cleaning member fastening part 143 that can be rotated by rotation of the motor,
The combined structure is,
It protrudes upward from one side (912, 1100) of the cleaning cloth (91, 1100) and includes a cleaner coupling portion (921, 1222) having a shape that can be fastened to the predetermined portion (143) of the cleaner (1, 2). do,
The above method is,
An operation of determining whether the predetermined portion 143 is disposed at a predetermined position for combination with the cleaning cloth 91, 1100, and
In response to the determination, the method includes an operation of driving the motor to rotate the cleaning member fastening portion 143 so that the cleaner coupling portions 921 and 1222 are fastened to the predetermined portion 143.
