The lidar is the device's main sensor, scanning rooms. It performs a 360-degree scan every second.
When viewed from above, the front panel contains three mechanical buttons that are responsible for starting the robot vacuum cleaner and directing it to recharge.

The front of the Xiaomi S55 features a mechanical bumper that moves when touched anywhere, sending a signal to the processor when an obstacle is detected. A sensor is located in the center and on the right side, measuring the distance to objects.

Functional capabilities
The Xiaomi Mi Roborock Sweep One S55 cleans with a single side brush, moving along the contours of the room so that the side brush is positioned on the side facing obstacles to sweep debris along them. The robot vacuum then moves in a shuttle pattern across the entire room, thanks to the lack of a second side brush.
Overcoming obstacles
The robot vacuum's turbo brush consists of a row of medium-hardness brushes and three curved silicone paddles. It has a working length of seventeen centimeters and is capable of effectively capturing larger solid debris as well as fine dust.
Main operating modes:
- quiet (400 Pa);
- standard (800 Pa);
- increased power (1200 Pa);
- maximum (2000 Pa).
The Xiaomi Mi Roborock S55 has a separate mode that allows the robot to move normally, where it only performs wet cleaning of the surface, while the side brush works and sweeps debris from the floor.
The Xiaomi robot vacuum cleaner automatically recognizes the type of surface being cleaned, selecting the most optimal cleaning mode. A separate liquid reservoir is provided for wet cleaning. As the robot mops, the microfiber cloth is automatically moistened thanks to a special smart water supply system. While the robot is working, water flows to the cloth; when the cleaning is complete, the system shuts off the water supply, preventing excess water.
Installing a wet cleaning unit
The robot vacuum cleaner is equipped with a lidar-based laser system that scans the surrounding space 360 degrees and uses SLAM algorithms. Based on this information, the robot creates a map of the room and creates a cleaning plan.
Building a map in the app
