Abstract
A vacuum cleaner according to one embodiment of the present invention is characterized in that whether to output a cleaning cloth replacement signal notifying about the replacement of a cleaning cloth is determined on the basis of the value of a mop motor (182) current measured by a current sensor.
Claims20
A cleaner comprising:
- a body;
- a rotary mop, on which a cleaning cloth is mounted, including a rotary plate rotatably installed on the body;
- a mop motor providing driving force to the rotary mop;
- a mop sensor measuring revolutions per minute (RPM) of the mop motor;
- a current sensor measuring a current value of the mop motor;
- and
- a controller determining whether to output a cleaning cloth replacement signal notifying about replacement of the cleaning cloth based on the current value of the mop motor measured by the current sensor.
