Document Type and Number:
WIPO Patent Application WO/2024/034798
Kind Code:
A1
Abstract:
A cleaner and an adjustment method for adjusting suction power according to suction pressure are provided. The cleaner according to one embodiment of the present disclosure comprises a pressure sensor, a current sensor, a suction motor, a brush motor, at least one memory for storing one or more instructions, and at least one processor, wherein the at least one processor executes the one or more instructions stored in the memory so as to detect, from the pressure sensor, suction pressure of air suctioned into the cleaner, acquire, from the current sensor, a driving current value of the brush motor, determine, on the basis of the suction pressure and driving current, whether the cleaner has been lifted up from the floor, and, if it is determined that the cleaner has been lifted up from the floor for a reference time or longer, lower the suction power of the cleaner by lowering the rotational speed of the suction motor.
