A moving robot is provided. The moving robot includes: a main body forming the exterior appearance; a moving means for moving the main body; a bumper configured to protrude on the outer perimeter of the main body; impact sensors placed at an angle on the main body to sense the movement of the bumper; and pressure parts formed in a bent shape at the end of the impact sensors.

A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.

An apparatus for cleaning a floor includes a housing, chassis, wheels, motor, steering mechanism, cleaning assembly, optionally a squeegee assembly, and at least one of a side sweeping system, front sweeping system, and pick-up system. The side sweeping system includes a turntable with central axis, a drive wheel disposed in coaxial relationship with the turntable, a sweeper motive device in communication with the drive wheel, a plurality of brushes distributed radially around the drive wheel and adapted to be driven by rotation of the drive wheel, and a pivoting connector configured to enable the side sweeping system to pivot laterally in response to contact with a wall while at least one of the brushes maintains contact with the floor adjacent the wall while the apparatus is in operation, and the brushes move debris disposed on the floor adjacent the wall toward the front of the apparatus.

A robot cleaner includes a main body forming an external appearance of the robot cleaner, moving units configured to move the main body, a cleaning module arranged at one side of the main body so as to contact a floor and rotated, a module driving unit arranged in the main body and rotating the cleaning module, and a dust pocket configured to remove foreign substances attached to the outer circumference of the cleaning module.

Disclosed is a floor cleaning device, including a water tank; a cleaning cloth wrapped around the water tank; a plurality of support shafts and a plurality of transmission shafts which are respectively provided in the water tank to support the cleaning cloth; a driving mechanism connected to the transmission shafts to drive the cleaning cloth to move circularly in the water tank; and a cleaning mechanism provided above the cleaning cloth to remove dirts on the surface of the cleaning cloth. The disclosure achieves a self cleaning at the same time of the floor cleaning, so that there is no need for the user to wash the used cleaning cloth or change a disposable cloth after the floor cleaning, realizing a true cleaning without producing the secondary pollution.

A self-propelled robot autonomously travels on a structure having a target plane and performs work on the plane of the structure. The robot includes a robot main body provided with a moving means for autonomous traveling, a control unit that controls movement of the robot main body, and a working unit that performs work on the target plane. The control unit includes an edge detection unit that detects an edge of the target plane, and the edge detection unit includes an outer detection unit located outward from the working unit in the traveling direction of the robot main body and an inner detection unit located closer to the robot main body than the outer detection unit in the traveling direction of the robot main body.

A robot cleaner includes a first cleaning module including left and right spin mops configured to rotate clockwise or counterclockwise when viewed from above while being in contact with a floor, and a second cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while being in contact with a floor, the rolling member being spaced apart from the left and right spin mops in an anteroposterior direction. A controller controls rotational motion of the left and right spin mops and rotational motion of the rolling member.

A rotary-body support structure includes: a rotary body including a rotary shaft and a contact portion spirally wound around the rotary shaft; and bearing parts that rotatably support the rotary body. The amount of engagement of the rotary body with a contact body that is in contact with the contact portion of the rotary body changes when the rotary body moves toward one side in a rotation axis direction.

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.
