• Advanced Dtof navigation technology: lefant T1 emits infrared light outward, and then reflects it to the end of the camera when it encounters an object. From this distance, the time difference or phase difference from the emission to the reflection back to the camera is calculated to obtain a three-dimensional and accurate 3D composition . Precise composition, precise cleaning, no dead space, and deep cleaning of the whole house.
