Lidar slam : It uses advanced laser radar, and simulaneous localization and mapping (SLAM) technology to build indoor environment maps, the machine is also integrated with various sensors such as infrared and interial navigation, and that help it to divide indoor space by block area, within which the machine may clean in zigzag or fixed-point type in a more efficient way. Snail Touch : It protrudes 3cm to the right front through the retractable side brush, increasing the corner cleaning coverage and to make the cleaning more thorough.
