A cleaning method and a cleaning robot are provided. The method includes: after the cleaning robot obtains a cleaning instruction for a target scene, acquiring a current power of the cleaning robot and a scene map for the target scene; if it is determined that the current power is insufficient to clean all areas to be cleaned in the target scene, determining a target cleaning area from all the areas to be cleaned in the target scene, based on a target dirtiness level for each of the areas to be cleaned; cleaning the target cleaning area based on the scene map, the target dirtiness level for the target cleaning area and the current power. A more intelligent cleaning robot and a more reasonable cleaning process are realized.

Provided is a robot including main and peripheral brushes; a first actuator; a first sensor; one or more processors; and memory storing instructions that when executed by the one or more processors effectuate operations including: determining a first location of the robot in a working environment; obtaining, with the first sensor or another sensor, first data indicative of an environmental characteristic of the first location; adjusting a first operational parameter of the first actuator based on the sensed first data to cause the first operational parameter to be in a first adjusted state while the robot is at the first location; and forming or updating a debris map of the working environment based on data output by the first sensor or the another sensor configured to collect data indicative of an existence of debris on a floor of the working environment over at least one cleaning session.

A vacuum cleaner includes a base defining a suction chamber, a user-manipulatable handle coupled to the base, a brushroll driven by a brushroll motor, a transmitter and a receiver both of which are in wireless communication with a user-controlled electronic device, and a controller in communication with the transmitter and the receiver. The controller controls the brushroll motor in a default mode wherein the brushroll is configured to run at a first percent of power on a first floor surface and a second percent of power on a second floor surface. The controller receives a communication from the user-controlled electronic device via the receiver and configured to cause the controller to turn off the default mode and run the brushroll at a third percent of power at both the first floor surface and the second floor surface.

The present disclosure provides a control method capable of, by using a current value of a nozzle, determining whether a nozzle is separated from a vacuum cleaner and whether the nozzle is reconnected to the vacuum cleaner after separation. To this end, a vacuum cleaner may comprise a nozzle connectable to a suction unit for suctioning dusts. The nozzle may comprise a rotary cleaning unit for applying pressure to a cleaning target surface so as to separate a foreign substance therefrom, and a nozzle motor for driving the rotary cleaning unit. In order to drive the nozzle, a voltage having been controlled by a pulse width modulation (PWM) method is applied, and a measurement unit included in the vacuum cleaner may measure a current value of the nozzle, the current value depending on the applied voltage.

A cleaner, according to one embodiment of the present invention, comprises: a cleaner main body comprising a suction motor, a dustbin and a battery; a suction nozzle having formed thereon an opening part for suctioning in external air; and an extension tube for connecting the cleaner main body and the suction nozzle. The suction nozzle comprises: a housing forming the exterior and the opening part of the suction nozzle; a rotational cleaning unit accommodated in the housing and cleaning a surface being cleaned by means of a rotational operation; a motor inserted in one side of the rotational cleaning unit so as to rotate same; a suction nozzle battery for supplying power for driving the motor; and a wireless power receiving unit connected to the suction nozzle battery so as to provide same with power supplied by an external wireless power transmission unit.

A floor treatment appliance with a replaceable change component, a detection device for detecting an actual parameter that is influenced by wear of the change component, an evaluation device for determining a degree of wear of the change component based on the actual parameter and a communication device for communicating information concerning a required replacement of the change component to an external terminal that is communicatively linked to the floor treatment appliance. The change component is a floor treatment element that mechanically acts upon a floor surface to be treated, and the evaluation device calculates an average value of the actual parameter detected by the detection device referred to a defined time period of at least one hour, compares the average value with a defined reference value and determines the degree of wear of the change component in dependence on the result of the comparison.

The invention pertains to a system consisting of a first floor treatment apparatus that is exclusively guided manually within an environment by a user and a second floor treatment apparatus that is exclusively operated automatically, wherein the second floor treatment apparatus is designed for orienting and localizing itself within an environment. The first floor treatment apparatus is designed for detecting a movement path of the first floor treatment apparatus during a movement of the first floor treatment apparatus that is manually guided by a user, as well as for transmitting information on the detected movement path to the second floor treatment apparatus by means of wireless communication. The second floor treatment apparatus is designed for receiving the information and for autonomously traveling along the movement path within the environment based on the received information.

A surface treatment apparatus may include a surface cleaning head having an agitator, an agitator motor configured to cause the agitator to rotate, and a controller. The controller can be configured to determine a surface type corresponding to a surface to be cleaned and to transition the surface treatment apparatus between a first operational mode and a second operational mode based, at least in part, on the determined surface type. Determining the surface type may include measuring a plurality values corresponding to a current draw of the agitator motor over a predetermined time window at a predetermined time interval, determining an average corresponding to the measured values, comparing the average to at least a first threshold, and transitioning the surface treatment apparatus between the operational modes based, at least in part, on the comparison.

A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

A method for adaptively operating a cleaning robot based on height difference between floors and the cleaning robot are provided, and according to an embodiment of the present disclosure, the cleaning robot that adaptively operates based on the height difference between the floors includes a central controller that controls a height adjuster that controls a height of a floor cleaner based on height information related to a space stored in a map storage and height information sensed by a sensor.
