Abstract: A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller configured to detect a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit. When there is a change in position and a change in load current, a specific area of a floor is determined to be a contaminated area.

Abstract: Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.

Abstract: The present application relates to a robot cleaner. The robot cleaner of the present application includes: a main body which forms an external shape; a water tank which stores water; a rotation mop which is in contact with a floor while rotating and moves the main body; a drive motor which rotates the rotation mop; a motion detection unit which measures a reference motion of the main body when the rotation mop rotates; and a controller which measures a slip rate based on an actual speed of the main body measured by the motion detection unit in the reference motion and an ideal speed of the main body estimated according to driving of the drive motor, and controls an amount of water supplied to the rotation mop.
