Review of the Xiaomi Robot Vacuum S20+: LDS Navigation and High Suction Power

Each new robot vacuum model usually surpasses its predecessor. The design is improved, becoming more compact and incorporating an increasing number of useful features. The functionality expands in new models, meeting a wide variety of user needs.
The Xiaomi Robot Vacuum S20+ is no exception. It combines many of the best features from previous models and enhances them further. This gadget boasts an excellent navigation system, thoroughly collects debris, removes stubborn stains, and can perform extended cleaning sessions on a single charge. In this review, we will take a detailed look at each feature of the device.
Design and Navigation
The robot vacuum’s body is made from durable materials to withstand collisions with various objects in its path. With a height of just 97 mm, the device can easily navigate under low-profile furniture, cleaning hard-to-reach areas. It features a roller brush and two mops for wet cleaning, positioned on either side of the vacuum and slightly extending beyond the body. This design allows it to clean right up against objects.
The Xiaomi Robot Vacuum S20+ is equipped with an advanced laser navigation system. It continuously scans the surrounding space and instantly maps the room in its memory. The device then uses this data to plan the most efficient cleaning routes. The precise LDS navigation ensures the vacuum can approach objects closely for thorough cleaning without colliding with them.
A combination of edge-detection and obstacle-avoidance sensors enables the robot vacuum to maneuver effectively across flooring, avoiding collisions and preventing falls from heights. The gadget also detects low spaces it cannot pass through. It performs quick mapping, supports multi-floor map storage, and resumes cleaning from the point it stopped.

Functionality and Control
The Xiaomi Robot Vacuum S20+ is powered by a high-speed motor, delivering a suction power of 600 Pa. This strong suction capability enhances the robot’s efficiency, allowing it to perform thorough cleaning on any type of flooring. The device achieves even better results with dual mops that rotate and simulate manual pressure on the floor, effectively removing stubborn stains.
This model offers four cleaning modes, with adjustable suction power across four levels at any time. The modes include: dry cleaning, wet cleaning, combined dry and wet cleaning, and sequential cleaning (vacuuming followed by mopping). The vacuum is equipped with carpet detection, automatically lifting the mops when moving over rugs to avoid damaging them and simultaneously increasing suction power for a deeper clean.
The robot supports remote control through multiple methods. Using the Xiaomi Home/Mi Home mobile app, users can set a cleaning schedule, switch between modes, adjust suction power, create restricted zones, and manually guide the robot. Additionally, voice control is supported when connected to devices compatible with Amazon Alexa or Google Assistant, making operation even more convenient.

Battery Life
The Xiaomi Robot Vacuum S20+ is equipped with a 5200 mAh battery, ensuring extended autonomous operation. The device can clean continuously for nearly 3 hours on a single charge. If the battery runs low during cleaning, the robot automatically returns to its charging dock and then resumes cleaning exactly where it left off.

Conclusion
The Xiaomi Robot Vacuum S20+ is a versatile robot vacuum with an advanced LDS navigation system, a high-capacity battery, powerful suction, and numerous other features.
Pros:
- Compact design
- Multiple detection and movement sensors
- 6000 Pa suction power with various cleaning modes
- Convenient remote control options
Cons:
- Lack of a multifunctional docking station with maintenance capabilities for the robot vacuum.
