    Abstract: The present disclosure relates to a cleaner with improved safety with respect to a cleaning module. According to an embodiment of the present disclosure, changes in postures of the cleaning module may be measured through one or more sensors included in a motion detecting part. Therefore, there is an advantageous effect that a problem for the user to have injuries by a mop containing high temperature steam does not occur. In addition, according to the present disclosure, a planar motion displacement of the cleaning module may be measured through one or more sensors included in the motion detecting part. Accordingly, when a control unit detects that the cleaning module is left in a state of contacting a surface to be cleaned for a long period of time, the drive of a feedwater pump, a heater, and a mop motor is controlled to stop. Therefore, there is an advantageous effect that the flooring of the surface to be cleaned is not damaged.

    Abstract: Provided is a cleaner including: a suction nozzle configured to suck in outside air; a brush motor configured to rotate a brush installed in the suction nozzle and sweeping up dust; a suction motor configured to generate a suction force of the suction nozzle; an acceleration sensor installed on the suction nozzle and configured to sense accelerations along three axes that are orthogonal to each other in a spatial coordinate system; a power supply unit configured to supply power to the brush motor and the acceleration sensor; and a controller configured to control the brush motor, the suction motor, and the power supply unit based on a variation of an x-axis acceleration provided by the acceleration sensor and a sum of acceleration variations which is obtained by summing variations of x-, y-, and z-axis accelerations provided by the acceleration sensor.

    Abstract: The present disclosure relates to a wet mop rag module for a cleaner, the wet mop rag module including a module housing, a water tank configured to store water therein, at least one rotary cleaning unit to which a mop rag is coupled, and a steam generator configured to heat water supplied from the water tank, in which the steam generator includes a heating chamber having a flow path in which moisture flows, a heater configured to supply heat to the heating chamber, and an overheating shut-off device configured to cut off a supply of power to the heater when a temperature of the heating chamber is equal to or higher than a predetermined reference temperature, thereby preventing the heating chamber from being overheated.
