How Does The LDS System Work

You might be wondering, what’s this LDS system in your Deebot and why is it so important? Let’s unravel this mystery together and understand its vital role in your robotic vacuum’s operation.

LDS stands for Laser Distance Sensor, a cutting-edge technology integrated into your Deebot that helps it navigate your home with remarkable precision. It’s like the eyes of your Deebot, scanning the surroundings constantly to create a virtual map of your home.

This enables your little helper to avoid obstacles, detect drops, and efficiently clean every nook and corner of your house without any supervision.

So, how does it work exactly? The LDS system projects a laser beam that bounces off surfaces and returns to the sensor.
