## Abstract

A cleaner for collecting dust is provided. The cleaner includes a suction head, a dust collector having a first end mounted on the suction head and including a first dust collecting chamber, an extension member slidably mounted on the dust collector at the other end opposite to the first end of the dust collector, and a first dirt removing member disposed at one end of the extension member and having elasticity.

## Claims

### Claim 1

A cleaner comprising:
a suction head;
a dust collector having a first end mounted on the suction head and including a first dust collecting chamber;
an extension member slidably mounted on the dust collector at a second end opposite to the first end of the dust collector; and
a first dirt removing member disposed at one end of the extension member and having elasticity.

### Claim 2 (depends on 1)

The cleaner according to claim 1,
wherein the dust collector includes a filtering device disposed inside the dust collector, and
wherein the filtering device is configured to filter dirt introduced through the suction head.

### Claim 3 (depends on 2)

The cleaner according to claim 2, wherein the first dirt removing member is configured to be slid on one surface of the filtering device on which dirt is filtered when the extension member slidingly moves with respect to the dust collector.

### Claim 4 (depends on 2)

The cleaner according to claim 2, further comprising:
a dirt separator disposed in a rear of the filtering device along a direction in which air introduced through the suction head is discharged.

### Claim 5 (depends on 4)

The cleaner according to claim 4, wherein the dirt separator includes a mesh member disposed inside the dust collector.

### Claim 6 (depends on 5)

The cleaner according to claim 5, further comprising:
a second dirt removing member configured to be slid on one surface of the mesh member on which dirt is filtered when the extension member slidingly moves with respect to the dust collector.

### Claim 7 (depends on 4)

The cleaner according to claim 4,
wherein the dirt separator is configured to generate at least one cyclone, and
wherein the dirt separator includes a second dust collecting chamber in which the dirt separated from the at least one cyclone is collected.

### Claim 8 (depends on 4)

The cleaner according to claim 4, wherein the first dirt removing member is configured to be movable from a first position between the filtering device and the dirt separator to a second position protruding outside the dust collector.

### Claim 9 (depends on 1)

The cleaner according to claim 1, further comprising:
a button device configured to fix a position of the extension member with respect to the dust collector.

### Claim 10 (depends on 9)

The cleaner according to claim 9, further comprising:
a fixing member,
wherein the button device includes a button configured to be movable with respect to the dust collector, and
wherein the fixing member is configured to fix or release the extension member with respect to the dust collector as the button is moved.

### Claim 11 (depends on 10)

The cleaner according to claim 10, wherein the button device further includes an elastic member for pressing the button to a fixing position so that the extension member is fixed with respect to the dust collector.

### Claim 12 (depends on 1)

The cleaner according to claim 1, further comprising:
a handle device disposed at the second end of the extension member opposite td one end of the extension member connected to the dust collector; and
a fan motor disposed inside the handle device for generating a suction force.

### Claim 13 (depends on 12)

The cleaner according to claim 12, further comprising:
a filter disposed in front of the fan motor along a direction in which air introduced into the handle device is discharged.

### Claim 14 (depends on 1)

The cleaner according to claim 1, further comprising:
a cover,
wherein the dust collector includes an opening/closing member having a chamber inlet through which air introduced from the suction head passes and configured to open and close the first dust collecting chamber, and
wherein the cover is configured to:
open and close the chamber inlet, and
open the chamber inlet in a direction in which air is introduced into the first dust collecting chamber.

### Claim 15 (depends on 2)

The cleaner according to claim 2,
wherein the dust collector includes an outer case and an inner case disposed inside the outer case to form a passage between the inner case and the outer case, and
wherein the filtering device is mounted on the inner case.

### Claim 16

A cleaner comprising:
a dust collector including a first dust collecting chamber;
an extension member slidably mounted on the dust collector at a first end of the dust collector;
a filtering device disposed inside the dust collector and for filtering dirt; and
a first dirt removing member configured to be slid on one surface of the filtering device on which the dirt is filtered when the extension member slidingly moves with respect to the dust collector.

### Claim 17 (depends on 16)

The cleaner according to claim 16, further comprising:
a dirt separator disposed in a rear of the filtering device along a direction in which air passing through the filtering device is discharged.

### Claim 18 (depends on 17)

The cleaner according to claim 17, wherein the first dirt removing member is movable from a first position between the filtering device and the dirt separator to a second position protruding outside the dust collector.

### Claim 19 (depends on 16)

The cleaner according to claim 16, further comprising:
a fixing member disposed to fix or release the extension member with respect to the dust collector; and
a button for guiding a movement of the fixing member.

### Claim 20

A cleaner comprising:
a suction head;
a dust collector having a first end mounted on the suction head and including a first dust collecting chamber;
an extension member slidably mounted on the dust collector at a second end opposite to the first end of the dust collector;
a filtering device disposed inside the dust collector and configured to filter dirt;
a first dirt removing member disposed in the extension member and configured to be slid in a state of being in close contact with the filtering device when the extension member slidingly moves with respect to the dust collector; and
a dirt separator disposed in a rear of the filtering device along a direction in which air introduced through the suction head is discharged.
