Document Type and Number:
WIPO Patent Application WO/2023/140592
Kind Code:
A1
Abstract:
The present invention comprises: a suction nozzle which sucks in external air; a brush motor installed on the suction nozzle to rotate a brush that sweeps up dust; a suction motor which generates a suction force of the suction nozzle; an acceleration sensor installed on the suction nozzle to sense accelerations in three axes of a spatial coordinate system, which are orthogonal to each other; a power supply unit which supplies power to the brush motor and the acceleration sensor; and a control unit which controls the brush motor, the suction motor, and the power supply unit, on the basis of an X-axis acceleration change amount provided from the acceleration sensor and a summed acceleration change amount obtained by summing X-axis, Y-axis, and Z-axis acceleration change amounts provided from the acceleration sensor.
