A robot cleaner comprising:
- a main body including a suction portion disposed thereon;
- main wheels for moving the main body;
- and
- a side brush assembly disposed on the main body, the side brush including:
- a housing forming an exterior of the side brush assembly;
- a first force transmitter disposed in the housing, the first force transmitter being configured to rotate by receiving a driving force;
- a belt connected to the first force transmitter;
- a second force transmitter connected to the first force transmitter by the belt, the second force transmitter being configured to receive a rotational force of the first force transmitter;
- and
- a side brush coupled to the second force transmitter,
- wherein the first force transmitter, the belt and the second force transmitter are configured to permit slip between the belt and one of the first force transmitter and the second force transmitter so that when slip occurs, a rotational angular speed of the first force transmitter and a rotational angular speed of the second force transmitter become different from each other.
A robot cleaner comprising:
- a suction portion including:
- an agitator configured to contact a floor and to rotate;
- and
- a suction hole configured to suck external foreign substances from the floor;
- main wheels for moving the robot cleaner;
- and
- a side brush assembly including:
- a first force transmitter configured to rotate by receiving a driving force;
- a belt connected to the first force transmitter;
- a second force transmitter connected to the first force transmitter by the belt to receive a rotational force of the first force transmitter;
- and
- a side brush coupled to the second force transmitter,
- wherein the first force transmitter, the belt and the second force transmitter are configured to permit slip between the belt and one of the first force transmitter and the second force transmitter so that when slip occurs, a rotational angular speed of the first force transmitter and a rotational angular speed of the second force transmitter become different from each other.
