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. The controller is configured to determine 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, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.
Claims13
A robot cleaner comprising:
- a spin module including left and right spin mops configured to rotate clockwise or counterclockwise while being in contact with a floor, and a spin drive unit including at least one motor connected to the left and right spin mops and configured to drive the left and right spin mops;
- a sensor unit comprising a plurality of sensors;
- and
- a controller configured to:
- determine a specific area of the floor to be a contaminated area based on data detected by the sensor unit,
- control the robot cleaner to perform a skirting traveling operation wherein the robot cleaner skirts around the contaminated area, or a concentrated cleaning operation wherein the robot cleaner cleans the floor in the specific area, and
- determine the specific area to be the contaminated area based on a change in load current of the at least one motor connected to the left and right spin mops.
