The motor is an important accessory of the intelligent sweeping robot. The speed of the motor directly affects the cleaning effect of the sweeping machine. The Ecovacs Magic Diamond intelligent sweeping robot uses a Nidec digital brushless motor imported from Japan, with a speed of up to 16,000 rpm, providing a super suction power of 1,000Pa to the body and not letting go of any tiny dust particles. At the same time, the brushless motor has low loss, high efficiency, and the noise can be effectively controlled. Together with Ecovacs' patented roller brush and floor-mounted suction nozzle, it has fully realized the self-transcendence of intelligent sweeping robots in the three aspects of "high power, low loss, and deep cleaning".
