A protective strip for protecting a fixture includes a piece of flexible material having a first edge and a second edge, and a plurality of magnets spaced along the first edge. In another example, a system for protecting a fixture includes a protective strip having a plurality of magnets spaced along a first edge, and a cart. The cart has a vertical member configured to hold the protective strip when the protective strip is rolled. A method is also disclosed.

A cleaner includes a body forming an external appearance, and a spin-mop cleaning module configured to support the body and including at least one spin-mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side. The inclination angle of a lower surface of the spin mop is changeable relative to a horizontal plane.

A system for collecting waste from an area includes a robotic device including a housing, a control system within the housing, which includes a processor system and a memory system in operative connection with the processor system, a power system in operative connection with the control system, a sensor system in operative connection with the control system, one or more drive wheels (each of the drive wheels being in operative connection with a motor which is in operative connection with the power system and with the control system), a waste retrieval system in operative connection with the power system and with the control system, and a receptacle compartment within the housing. The control system includes one or more location/identification algorithms stored in the memory system and executable by the processor system to locate an object of animal waste in the area based upon data received from the sensor system. The control system further includes one or more positioning algorithms stored in memory and executable by the processor system to position the robotic device relative to the object of animal waste to enable collection of the object of animal waste via the waste retrieval system. Additionally, the control system includes one or more retrieval algorithms to actuate the waste retrieval system and control the waste retrieval system to bring the object of animal waste into the receptacle compartment.

Disclosed herein is a robot cleaner including a driving motor, a communication interface configured to receive, from an external cleaner, first cleaning record information including cleaning path information generated based on location information of the external cleaner, a memory configured to store second cleaning record information including the cleaning path information generated based on location information of the robot cleaner, and a processor configured to generate a cleaning plan of the robot cleaner based on the first cleaning record information and the second cleaning record information and control the driving motor such that the driving motor travels according to the cleaning plan.

A cleaning robot include a main body and a cleaning module. The cleaning module includes a box body, at least one driving mechanism, and at least one rotating plate assembly. The box body includes a first connector. The at least one driving mechanism is positioned on a bottom surface of the box body, electrically connected to the first connector, and includes at least one drive shaft. Each rotating plate assembly is connected to a corresponding drive shaft and includes a cleaning surface. The cleaning surface is configured to rotate under the drive of the corresponding drive shaft to clean a to-be cleaned surface. The main body includes a second connector. The box body is detachably positioned on the main body, such that the first connector is connected to or disconnected to the second connector.

An autonomous cleaning robot includes a drive system to maneuver the autonomous cleaning robot across a floor surface; a cleaning assembly for cleaning the floor surface; and a sensor system disposed at a forward portion of the autonomous cleaning robot. The sensor system includes a movable element having (i) a first configuration in which the movable element extends beyond a bottom surface of the autonomous cleaning robot by a first amount, and (ii) a second configuration in which the movable element extends beyond the bottom surface of the autonomous cleaning robot by a second amount less than the first amount; a spring mechanically coupled to the movable element, the spring being biased to hold the movable element in the first configuration; and a sensor assembly configured to generate a signal based on the configuration of the movable element.

A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.
