## Abstract

The present disclosure provides a cleaning device, cleaning apparatus and cleaning method. The cleaning device including a cleaning portion and at least one liquid amount control portion, the cleaning portion includes a cleaning surface which is capable of absorbing a cleaning liquid for cleaning an object to be cleaned; and the at least one liquid amount control portion is configured to be able to contact the cleaning surface and apply a contact pressure to the cleaning surface, so as to control a amount of the cleaning liquid contained in the cleaning surface of the cleaning portion as a generally determined value when in contact with the object to be cleaned.

## Claims

### Claim 1

A cleaning device including a cleaning portion and at least one liquid amount control portion, wherein
the cleaning portion includes a cleaning surface which is capable of absorbing a cleaning liquid for cleaning an object to be cleaned;
the at least one liquid amount control portion is configured to be able to contact the cleaning surface and apply a contact pressure to the cleaning surface, so as to control an amount of the cleaning liquid contained in the cleaning surface of the cleaning portion as a generally determined value when the cleaning surface is in contact with the object to be cleaned, and
wherein a first liquid amount control portion is configured to contact the object to be cleaned and be able to transmit the object to be cleaned by rotation.

### Claim 2 (depends on 1)

The cleaning device according to claim 1, wherein the at least one liquid amount control portion includes a roller.

### Claim 3 (depends on 1)

The cleaning device according to claim 1, wherein the cleaning surface includes a water-absorbing material selected from the group consisting of a cloth, a brush, and a sponge.

### Claim 4 (depends on 1)

The cleaning device according to claim 1, wherein the cleaning portion includes a cleaning roller, and the cleaning roller is configured to be rotatable for a cleaning operation.

### Claim 5 (depends on 4)

The cleaning device according to claim 4, wherein the at least one liquid amount control portion is provided to extend in an axial direction of the cleaning roller.

### Claim 6 (depends on 5)

The cleaning device according to claim 5, wherein a length of the at least one liquid amount control portion in the axial direction of the cleaning roller is the same as an axial length of the cleaning roller.

### Claim 7 (depends on 4)

The cleaning device according to claim 4, further comprising a second liquid amount control portion, wherein the first liquid amount control portion and the second liquid amount control portion are disposed on a front side and a rear side, respectively, of a position of the cleaning portion; wherein the second liquid amount control portion is configured to contact the object that has been cleaned, and be able to transmit the object that has been cleaned by rotation.

### Claim 8 (depends on 1)

A cleaning apparatus including a cleaning device according to claim 1.

### Claim 9 (depends on 8)
