An automatic cleaning apparatus is configured to clean a floor and emit ultraviolet light for sterilizing the floor in a cleaning mode. Upon detecting that a wall is nearby, the automatic cleaning apparatus emits ultraviolet light toward a corner formed by the floor and the wall for sterilization.

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 robot cleaner includes a body, a first rotating plate, a second rotating plate, a first mop, a second mop, a first support wheel, a second support wheel, and a first lower sensor. The first lower sensor is configured to sense a relative distance from a floor. The first lower sensor is located between the first support wheel and the second support wheel, and is located further away from the first rotating plate and the second rotating plate than the first support wheel and the second support wheel. The robot cleaner may move while being supported by the first mop, the second mop, the first support wheel, and the second support wheel, and easily avoid a cliff in which the floor suddenly drops.

A multifunctional cleaning device includes a main body, a telescopic tube body, a cleaning head set and a control unit. Multiple drive units are mounted on one side of the main body. The main body has a detection unit for detecting cleaning range and path. The telescopic tube body is telescopically connected with the main body. The telescopic tube body has a first end and a second end. The first and second ends are respectively connected with the main body and the cleaning head set in communication therewith. The control unit is disposed in the main body to execute system control and judge received signals so as to give commands to the drive units for controlling the move of the main body.

A surface cleaning apparatus, such as a fluid delivery or steam mop, comprises a handle assembly comprising a steam distributor and a foot assembly pivotally attached to the handle assembly and comprising a base housing. The foot assembly can be used in two positions, whereby opposing sides of a cleaning pad on the base housing can selectively engage a surface to be cleaned. The foot assembly is further swivelable relative to the steam distributor, such that fluid can be delivered to the surface to be cleaned in both of the two use positions.

An autonomous floor cleaning robot includes a body, a controller supported by the body, a drive supporting the body to maneuver the robot across a floor surface in response to commands from the controller, and a pad holder attached to an underside of the body to hold a removable cleaning pad during operation of the robot. The pad includes a mounting plate and a mounting surface. The mounting plate is attached to the mounting surface. The robot includes a pad sensor to sense a feature on the pad and to generate a signal based on the feature, which is defined in part by a cutout on the card backing. The mounting plate enables the pad sensor to detect the feature. The controller is responsive to the signal to perform operations including selecting a cleaning mode based on the signal, and controlling the robot according to a selected cleaning mode.

A cleaning robot system including a robot and a robot maintenance station. The robot includes a robot body, a drive system, a cleaning assembly, and a cleaning bin carried by the robot body and configured to receive debris agitated by the cleaning assembly. The robot maintenance station includes a station housing configured to receive the robot for maintenance. The station housing has an evacuation passageway exposed to a top portion of the received robot. The robot maintenance station also includes an air mover in pneumatic communication with the evacuation passageway and a collection bin carried by the station housing and in pneumatic communication with the evacuation passageway. The station housing and the robot body fluidly connect the evacuation passageway to the cleaning bin of the received robot. The air mover evacuates debris held in the robot cleaning bin to the collection bin through the evacuation passageway.

A cleaning system comprising a vacuum source, a current sensor, a recovery tank having a shutoff float configured to float on a surface of fluid within the recovery tank, and a controller. The vacuum source is in fluid communication with a suction inlet via first and second air paths within the recovery tank. The shutoff float is further configured to block the first air path upon the fluid within the recovery tank reaching a desired level. The controller is configured to receive, from the current sensor, a signal indicative of the current drawn by the vacuum source. The controller is further configured to determine, based on the current drawn by the vacuum source crossing a threshold, the fluid within the recovery tank has reached the desired level and control an operating element of the cleaning system upon determining the fluid within the recovery tank has reached the desired level.

A floor cleaning machine including an electrochemical cell having an anode, a cathode, an electrolyte, an electrochemical cell controller in at least one of unilateral and/or bilateral communication with at least one of the anode, the cathode, and the electrolyte, and wherein the electrochemical cell is associated with at least one of a recovery tank sub-assembly, a vacuum fan sub-assembly, a solution tank sub-assembly, a solution flow sub-assembly, a control console sub-assembly, at least one of a frame and wheel sub-assembly and a frame and transaxle sub-assembly, a scrub head sub-assembly, a scrub head lift sub-assembly, and a squeegee sub-assembly.

A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.
