Abstract: A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.

Abstract: A cleaner includes: a body which forms an outer appearance; and a mop module which is detachably connected to the body. The mop module includes: a pair of spin mops which contacts a floor while rotating clockwise or counterclockwise when viewed from a top; and a module housing which connects the pair of spin mops. The cleaner may travel autonomously due to the rotation of the spin mops.

Abstract: A cleaner includes a first cleaning module including a left spin mop and a right spin mop configured to contact the floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module configured to contact the floor in front of the first cleaning module, and a body supported by the first cleaning module and the second cleaning module. A point on the bottom surface of the left spin mop that receives the largest frictional force from the floor is located on a left-front side of the rotation center of the left spin mop, and a point on the bottom surface of the right spin mop that receives the largest frictional force from the floor is located on a right-front side of the rotation center of the right spin mop.

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.
