The navigation system of the Xiaomi Mi Roborock Sweep One S55 robot vacuum cleaner consists of a laser rangefinder and a set of obstacle sensors that provide optimal movement during cleaning. Determines terrain features, builds a map, sees elevation differences. Remotely controlled. Provides dry and wet cleaning. A similar model of the manufacturer - S50, differs in color, body is white, S55 is black. Another design option is offered by the S52 model - with the emblem of the Inter football team. What the Roborock S55 robot vacuum cleaner offers - its functionality, pros and cons, we will consider in the review.
Specifications
- Powered by 5200 mAh Li-lon battery, provides 2.5 hours of operation, charging lasts 2.5-3 hours. During this time, it manages to process up to 250 square meters of premises.
- Suction power 400-2000 Pa.
- Pass obstacles up to 2 cm high.
- Garbage container for 640 ml.
- Height 9.7 cm.
- Noise during operation no more than 54 dB.
- In the waste container, a HEPA filter of class E11, a protective Teflon coating, filters out up to 95% of small debris.
Design
The body of the robot vacuum cleaner Xiaomi Mi Roborock Sweep One S55 is made of plastic with a glossy finish, as mentioned above, in black. Dimensions are small - diameter 35 cm, height only 9.65, this figure was measured to the protrusion of the laser rangefinder. Lidar is the main sensor in the navigation system; it scans the space 360 degrees and updates the data on obstacles on the way every second.
On the top panel there are 3 mechanical control buttons that can be used to launch Roborock S55 or direct it to the docking station. On the front there is a mechanical bumper with a slight backlash when it comes into contact with objects. If a touch occurs, information about this goes to the processor and the robot realizes that it has stumbled upon an object. This algorithm, coupled with the work of the lidar, helps the vacuum cleaner build a map of the room.
On the opposite side there are 4 height difference sensors and a pair of large tires with rubber tread, a front wheel for maneuvering. There are also two contacts for connecting to a charging station, a side brush, a main turbo brush and a battery compartment.
Functional
For cleaning in the Xiaomi Mi Roborock Sweep One S55 robot vacuum cleaner, only one side brush is provided, but the movement algorithm is configured in such a way that it is always on the side of the obstacle when the vacuum cleaner moves around the perimeter of the room. Effectively cleans up space along walls. After passing through all the walls, the robot begins to move with the shuttle around the space of the room, which explains the absence of the need for a second brush.
The main turbo brush is designed as a row of medium hardness brushes and three curved silicone blades. The working surface is 17 cm long, it picks up solid debris and small dust particles and directs them to the suction inlet. The noise level is determined by the operating mode and the suction power:
- 400 Pa - quiet mode;
- 800 Pa - standard;
- 1200 Pa - increased power;
- 2000 Pa - maximum.
Another mode is normal movement, the robot carries out wet cleaning, during wet cleaning, the side brush continues to work, it sweeps debris from the surface.
The vacuum cleaner has surface recognition function, it selects the mode suitable for carpet or hard floor. Wet cleaning is carried out using a separate fluid reservoir. Water is supplied to the napkin automatically by an intelligent system.While the vacuum cleaner is moving, water is supplied, as soon as its movement stops, the water supply also stops. This prevents puddles from forming under the bottom, even if the robot is stuck in wires or skidded.
A laser system is used for navigation, it scans the surrounding space in a circle, and SLAM algorithms are implemented. Based on the data obtained, a map of the room is built and a plan for cleaning it is created.
The control system is implemented using buttons on the case and through the proprietary Mi Home application. In it, you can set up operating modes, build a cleaning schedule, independently build a movement plan, set marks restricting movement and much more.
Equipment

Pros and cons
After analyzing the characteristics and customer reviews of the Xiaomi Mi Roborock Sweep One S55, I have identified the following pros and cons.
Benefits:
- Modern and stylish design in three color options.
- Small overall.
- Voice commands and sound indication during operation.
- High-capacity battery.
- High suction power with the ability to increase and decrease, which regulates the sound of work, the speed of the end of the battery charge.
- Wet cleaning with the supply of water to the napkin from the container by automatic equipment brings you closer to full-fledged wet cleaning.
- Connecting to a smartphone via an app.
- Main turbo brush.
- Low noise level during operation.
Disadvantages:
- The set does not include a remote control and a motion limiter, but the motion limiter function is in the application, where you can indicate places in the room that the robot should not enter.
- Only one turbo brush, contrary to the manufacturer's statements, it still reduces the overall efficiency.
- Not Russified.
- At the moment it has not yet been officially presented in our country.
