Choosing an automatic cleaning assistant has become a challenging quest because of the sheer number of models produced by the Mijia ecosystem. At first glance, all devices seem the same: a round case, a pair of rotating brushes and a smartphone app. However, the price difference between the base model and the flagship can be as high as threefold, and it is not in branding, but in navigation technology and cleaning quality.
To avoid overpaying for unnecessary functions or, conversely, not to buy a device that will get stuck on the doorsteps, you need to understand the key differences in the hardware. It depends on the type of sensors and the design of brushes whether the gadget will become your best friend or the next dust collector in the corner.
In this article, we will take a closer look at how different lines differ, what types of wet cleaning are available, and what to look for when buying this year, and you will learn to read specifications and understand which use case is right for your home.
Navigation: LDS vs LiDAR and gyroscope
The most important factor that influences cleaning efficiency and device price is the spatial orientation system. Budget models often have a gyroscope that allows you to build a rough layout of the room, but sees no obstacles in real time, and these robots move along algorithmic lines, sometimes hitting furniture.
More advanced versions use a laser rangefinder (LDS) located in a characteristic bump on the top panel, which rotates and scans the room, creating an accurate map, the robot with LDS will never get lost, can clean up the rooms and return to the base to recharge to continue from the interrupted place.
Flagship models are moving to LiDAR technology, or a combination of a laser with visual navigation (cameras), which allows the device not only to map, but also to recognize objects: wires, socks, toys, such robots bypass obstacles, not push them.
- 📍 Gyroscope – chaotic movement, no map, low price.
- 📍 LDS (laser) – accurate map, cleaning rooms, average price tag.
- 📍 LiDAR + AI — object-recognition, 3D-card, high cost.
⚠️ Note: Models without laser rangefinder (LDS) They can’t build a permanent map in the app, so you can’t set virtual walls or no-go areas for cleaning.
If you have a lot of small objects on the floor or have pets, it is best to look straight at models with LDS or camera. Gyroscopic models are only suitable for studios with minimal furniture and free flooring.
Types of wet cleaning: from simple rag to car wash
Many users mistakenly believe that all robots clean floors the same way, and there are actually three fundamentally different approaches to implementing wet cleaning, and you shouldn't confuse them.
The first and easiest option is passive wet cleaning, and you attach a plastic platform with a microfiber to the bottom of the robot, which is slightly pressed to the floor, and the robot just carries a wet cloth behind it, which is effective only against fresh dust, but it won't wash away dried stains.
The second level is the vibration platform, where the rag is mounted on a plate that performs high-frequency vibrations (up to 3,000 times per minute), which mimics the movement of a person's hand and allows for the removal of more serious contaminants, systems that are often found in mid- and high-end models.
The third, most technologically advanced option is rotating disks or even full-fledged self-cleaning stations, where two round rags rotate, actively cleaning the floor, and after cleaning, the robot comes to the base, where they are automatically washed off and dried with hot air.
| Type of cleaning | Efficiency | Availability in models | Price. |
|---|---|---|---|
| Passive (rag) | Low (dust collection) | Budgetary (Lite, Essential) | $ |
| Vibration. | Medium (spots) | Medium (Pro, G10) | $$ |
| Rotating discs | High (pollution) | Flagships (X10+, X20+) | $$$ |
When choosing a device, honestly answer yourself: do you need a full floor wash or just keep the floor fresh? For families with young children who often pour juices, a passive rag will be useless.
Brush design and suction capacity
Suction power, measured in Pascals (Pa), is a marketing parameter that is often looked at first. 4000-5000 Pa looks impressive, but the real efficiency depends on the design.
The classic main brush is a villi shaft. It collects dust well, but animal hair and fur are often wound on it, requiring regular cleaning with scissors. For pets owners, this can be a problem.
The alternative is a lilaless brush (Silent Brush or equivalent), which is made of tight rubber with a slanted tread pattern, which is almost no way to collect hair, it's just sucked into a container, but on high-pile carpets, the effectiveness of a rubber brush may be lower.
The suction power only makes sense when it's coupled to a good turbobrush, and if the duct is poorly designed, even 5,000 Pa won't pull the trash out of the carpet, and at maximum power, the robot runs very loudly and discharges quickly.
- 🌀 Pile brush is better for carpets, but confuses hair.
- 🌀 Rubber brush – perfect for wool, easier to clean.
- 🌀 Side brush - mandatory for knocking garbage out of corners.
⚠️ Attention: Do not chase the record indicators of Pa. For an ordinary apartment with laminate and carpets is quite enough 2500-3000 Pa, which will provide silence and economical battery consumption.
Note the volume of the dust container. LDS models usually have a smaller dust collector because of the laser module, and if you have a large apartment and a lot of garbage, you have to shake it out after each cleaning.
App and ecosystem: Mi Home vs Xiaomi Home
Software is your robot’s brain. Mi Home has long been the standard, but in 2023-2026, the company began actively migrating devices to the new Xiaomi Home platform, causing confusion among users, as old models may not be supported by the new app and new ones may not be supported by the old one.
The app configures maps, schedules and zones, and allows you to create multi-storey maps (relevant to multi-level homes), adjust the sequence of cleaning rooms, and install virtual walls.
An important aspect is the integration with voice assistants. Officially, Xiaomi robots are friends with Alice (via the help of the voice assistants_skill_), Google Assistant and Amazon Alexa. However, voice control functionality is often limited to running a cleanup or sending it to base.
For advanced users, integration into smart home systems like Home Assistant is important. Most Xiaomi robots (especially those released for the global market) have open protocols or are easily hacked through a local server (such as Valetudo), which allows them to be managed without the cloud.
What if the robot is not visible in the app?
Connection stability depends on the router, and if the robot is constantly losing communication, it may be worth decoupling it with a separate guest network or using a Wi-Fi repeater in the middle of the apartment.
Autonomy and types of charging station bases
The average time of modern models is 90 to 180 minutes in quiet mode, enough to clean an apartment of up to 150-200 square meters, and the key function here is to return to the base for recharging and continue cleaning (Recharge & Resume).
The conventional base simply charges the device, and the more expensive stations have a powerful compressor that sucks garbage out of a small robot container into a large bag in the base, so you can forget about cleaning for 1-2 months.
Top models are equipped with combined stations that not only suck dust, but also replenish the water tank, wash and dry rags, which take up more space and require connection to the water supply (in some versions) or frequent manual water change.
- 🔋 Standard base - only charging.
- 🔋 Auto-Devastatement Base - for Allergics and Large Apartments.
- 🔋 Full station - washing, drying, charging (maximum comfort).
When choosing a car-devouring station, consider the noise level. The dust-pumping process takes 10-15 seconds and sounds like a plane taking off. Don't put such bases in the bedroom or nursery if you plan to start cleaning during the day or evening.
⚠️ Warning: Dust bags in auto-waste stations are consumables, and check in advance for their cost and availability in your area, as the original ones can be expensive.
💡
If you have dark carpets or furniture, seal the fall sensors on the robot body with pieces of white tape, otherwise it may think that it is above the cliff and refuse to go to a dark surface.
Comparison of popular Xiaomi and Mijia series
It's hard to understand the nomenclature because the names change, and conventionally, all models can be divided into several lines, each with its own characteristics.
The Essential/Lite series is the entry ticket to the world of robotic cleaning. There's no laser rangefinder, the cleaning is chaotic or simple, a good option for a first purchase or a small studio.
The Pro/G series is the middle ground. It already has LDS, an accurate map, good power, and often a vibration washing platform, and these are the most popular models because of the balance of price and quality.
X/Ultra Series – flagships with all possible options: AI-Cameras, self-service stations, rotating cloths, that's a choice for those who want to get the most automation and are willing to pay for it.
Separately, Dreame and Roborock are sub-brands of the Xiaomi ecosystem that often release more advanced devices under their own name but are controlled through the same apps. For example, the Roborock S7 or Dreame L10s Ultra are technically Xiaomi Ecosystem devices.
| Series | Navigation | Wet cleaning | For whom? |
|---|---|---|---|
| Essential | gyroscope | Passive | Small apartments, economy |
| Pro / G | LDS (Laser) | Vibration. | Standard apartments |
| X / Ultra | LiDAR + Camera | Rotation + Wash | Big houses, pets. |

FAQ: Frequently Asked Questions
Can you run a Xiaomi robot vacuum cleaner without the Internet?
Does a robot fear water when washing floors?
How often should filters and brushes be changed?
Does the robot work on black carpets?
💡
The main criterion for choosing is the presence of a laser rangefinder (LDS), without which the robot will not be able to effectively remove complex layout, regardless of other characteristics.
To sum up, Xiaomi's robot vacuum cleaner choice depends on your specific conditions. For a small apartment without carpets, a budget model with a gyroscope will suffice. For a large family with pets and carpets, you must have a budget model with a gyroscope. LDS-navigation and auto-devour station, carefully study the characteristics, so that the equipment lasts long and enjoys cleanliness.
