## Abstract

A cleaning system, including a robot cleaner and a station are provided. The cleaning system includes a robot cleaner including a dust collector, the dust collector provided with a dust outlet, and an outlet door configured to open and close the dust outlet. The robot cleaner further includes a station including a lever device configured to open the outlet door and communicate with the dust collector when the lever device is pressed by the robot cleaner, and a collector configured to communicate with the lever device, and generate a suction force to suction dust collected in the dust collector.

## Claims

### Claim 1

A cleaning system comprising:
a robot cleaner including:
a dust collector provided with a dust outlet, and an outlet door configured to open and close the dust outlet; and
a station including:
a lever device configured to open the outlet door and communicate with the dust collector when the lever device is pressed by the robot cleaner, and
a collector configured to:
communicate with the lever device, and
generate a suction force to suction dust collected in the dust collector,
wherein the station comprises a cleaner seating portion on which the robot cleaner is seated,
wherein the lever device includes:
a lever having one end configured to be pressed by the robot cleaner, and
a connection member arranged at the other end opposite to one end of the lever, the connection member configured to be connectable to the dust outlet,
wherein, when the robot cleaner is seated on the cleaner seating portion, the robot cleaner is positioned to press the lever, and
wherein, when the lever is pressed by the robot cleaner, the lever is rotated and moves the connection member toward a direction in which the connection member is connected to the dust outlet.

### Claim 2 (depends on 1)

The cleaning system of claim 1, wherein the outlet door is slidable about the dust collector.

### Claim 3 (depends on 2)

The cleaning system of claim 2, wherein the robot cleaner comprises a door elastic member configured to apply an elastic force to the outlet door in a direction of closing the dust outlet.

### Claim 4 (depends on 1)

The cleaning system of claim 1, wherein the robot cleaner further includes:
a cleaner inlet formed toward a surface to be cleaned;
a cleaner suction device configured to generate a suction force to suction dust; and
a cleaner outlet configured to discharge air introduced through the cleaner inlet.

### Claim 5 (depends on 4)

The cleaning system of claim 4, wherein the robot cleaner further includes a drum blade arranged on the cleaner inlet.

### Claim 6 (depends on 1)

The cleaning system of claim 1,
wherein the lever device further includes:
a lever support member configured to rotatably support the lever.

### Claim 7 (depends on 1)

The cleaning system of claim 1, wherein, when the robot cleaner is seated on the cleaner seating portion, the connection member slides along a surface on which the dust outlet of the dust collector is formed, and the connection member opens the outlet door.

### Claim 8 (depends on 1)

The cleaning system of claim 1,
wherein, when the robot cleaner is seated on the cleaner seating portion, the connection member protrudes to an outside of the cleaner seating portion so as to be connected to the dust outlet, and
wherein, when the robot cleaner is not seated on the cleaner seating portion, the lever protrudes from the outside of the cleaner seating portion.

### Claim 9 (depends on 1)

The cleaning system of claim 1, wherein the lever device comprises a lever elastic member configured to apply an elastic force to the lever to allow one end of the lever to protrude from the cleaner seating portion.

### Claim 10 (depends on 1)

The cleaning system of claim 1, wherein the collector comprises:
a station suction device configured to generate a suction force;
a collection chamber in which dust suctioned from the robot cleaner is collected; and
an extension member configured to connect the connection member to the collection chamber.

### Claim 11 (depends on 10)

The cleaning system of claim 10, wherein the extension member comprises a stretching member provided to be stretchable.

### Claim 12 (depends on 10)

The cleaning system of claim 10 wherein the station comprises a station outlet configured to discharge air suctioned by the station suction device.

### Claim 13 (depends on 1)

The cleaning system of claim 1, wherein the connection member comprises a sealing member configured to seal a periphery of the dust outlet when the connection member is connected to the dust outlet.

### Claim 14 (depends on 1)

The cleaning system of claim 1,
wherein the robot cleaner comprises a battery mounting portion and a cleaner charging terminal electrically connected to the battery mounting portion, and
wherein the station comprises a station charging terminal provided to be electrically connected to the cleaner charging terminal when the robot cleaner is seated on a cleaner seating portion.

### Claim 15

A station comprising:
a cleaner seating portion on which a robot cleaner is seated;
a lever device arranged in the cleaner seating portion, the lever device configured to communicate with a dust collector provided in the robot cleaner when being pressed by the robot cleaner; and
a collector configured to:
communicate with the lever device, and
generate a suction force to suction dust collected in the dust collector,
wherein the station comprises a cleaner seating portion on which the robot cleaner is seated,
wherein the lever device includes:
a lever having one end configured to be pressed by the robot cleaner, and
a connection member arranged at the other end opposite to one end of the lever, the connection member configured to be connectable to a dust outlet,
wherein, when the robot cleaner is seated on the cleaner seating portion, the robot cleaner is positioned to press the lever, and
wherein, when the lever is pressed by the robot cleaner, the lever is rotated and moves the connection member toward a direction in which the connection member is connected to the dust outlet.

### Claim 16 (depends on 15)

The station of claim 15, wherein the lever device further comprises a sealing member configured to seal a portion in contact with the robot cleaner to communicate with the dust collector.

### Claim 17 (depends on 15)

The station of claim 15, wherein the lever device further comprises:
a lever support member configured to rotatably support the lever; and
a lever elastic member configured to elastically press the lever to a direction of protruding from the cleaner seating portion.

### Claim 18
