A cleaner includes a battery which is detachable from a main body, a printed circuit board (PCB) provided in the main body, a first connector provided on the PCB and including a first terminal portion, a second connector provided in the battery and including a second terminal portion coupled to the first terminal portion when the battery is mounted onto a battery mounting portion, and a heat dissipation structure provided on the PCB and configured to dissipate heat from the first terminal portion. The heat dissipation structure including a heat dissipation pad provided on the PCB and a plurality of heat dissipation patterns arranged two-dimensionally on the heat dissipation pad.

Cleaner with heat dissipation structure

A method of controlling an operation of a cordless vacuum cleaner includes storing information about predefined movement patterns corresponding to a plurality of control commands in a memory of the cordless vacuum cleaner, in response to detecting that docking or charging of the cordless vacuum cleaner on a station device is terminated, detecting at least one movement pattern among the predefined movement patterns by analyzing movement information obtained via at least one motion sensor, identifying at least one control command corresponding to the detected at least one movement pattern, and controlling an operation of the cordless vacuum cleaner based on the identified at least one control command.

Cordless vacuum cleaner and method of controlling operation of cordless vacuum cleaner

A cleaning device including a suction motor; a suction head including a suction port; a rotatable brush inside the suction head; a brush motor; a pressure sensor; a memory storing coefficient tables including coefficients of a hyperplane equation for determining a type of surface to be cleaned; and a controller. The controller is configured to, in a first state with the suction head separated from the surface, select a reference coefficient table corresponding to a first suction pressure and a first load of the brush motor, in a second state with the suction head in contact with the surface, identify a type of the surface based on a second suction pressure, a second load of the brush motor, and the reference coefficient table, and adjust an output of the suction motor and/or the brush motor based on the identified type of the surface to be cleaned.

Cleaning device and control method thereof

An operating method of a station device for discharging dust from a cordless vacuum cleaner includes detecting occurrence of an event requesting discharging dust from a dustbin included in the cordless vacuum cleaner to the station device, and performing a dust discharge operation for discharging dust in the dustbin to a collector of the station device based on detecting of the occurrence of the event. The performing a dust discharge operation includes transmitting, to the cordless vacuum cleaner via short-range wireless communication, a control signal for operating a first suction motor of the cordless vacuum cleaner, and operating a second suction motor of the station device in cooperation with the first suction motor.
