According to Zhong Yi Finance Network, Dyson v 12 was officially listed on March 5, 20021. Dyson v 12 laser detection technology mainly uses laser to replace the conventional LED light source. The green laser diode is placed on one side of the end cover of the suction head. The laser is 7.3 mm away from the ground and forms an angle of 65438 0.5 with the ground. After being refracted by a special lens, it diverges outward to illuminate the area in front of the suction head. Dust on the floor can be instantly visualized by green laser.
