Abstract: A cleaner is provided. The cleaner includes a pressure sensor, a current sensor, a suction motor, a brush motor, memory, comprising one or more storage media, storing instructions, and one or more processors coupled to the pressure sensor, the current sensor, and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the cleaner to obtain a suction pressure value of air sucked into the cleaner from the pressure sensor, obtain a driving current value of the brush motor from the current sensor, determine whether the cleaner has been lifted up from a floor based on the suction pressure value and the driving current value, and decrease suction power of the cleaner by decreasing a rotation speed of the suction motor according to a determination that the cleaner has been lifted up from the floor for a reference time or more.
