The modern smart-tech market is oversaturated with offerings, and it’s getting harder to choose the perfect cleaning gadget. Xiaomi has been leading the way for years, offering solutions from budget washers to advanced AI stations. If you’re confused about LDS, LiDAR and wet cleaning types, this material will help you figure it out.
The challenge is that one brand is a very different ecosystem and navigation technology, and some models just randomly poke around the walls until they've cleared the floor, while others build the most accurate map of the space in minutes, and understanding these differences is the key to buying that won't disappoint.
In this article, we're not just going to list the characteristics, but we're going to look at why suction power isn't the only parameter worth looking at, and how having an ultrasonic sensor actually affects the quality of life of a carpet owner, and choosing the right one will save you hundreds of hours of free time in the future.
The evolution of navigation: from gyroscope to LiDAR
The first thing a customer encounters is the type of navigation that determines whether a robot will take a logical route or operate in a drunken penguin mode. Budget models often have a gyroscope that only roughly tracks traffic, leading to skips and long work.
The gold standard for Xiaomi is LiDAR laser navigation. The turret on the device's body rotates, scanning the room and creating a digital map. This allows the robot to not just drive, but to understand where it is, and plan the optimal path. In 2026, buying a model without a laser makes sense only on a very limited budget.
Why does the robot lose the map?
It is important to note the difference between conventional laser navigation and advanced systems with a high-performance laser navigation system. AI-The camera recognizes objects in real time, by going around wires, socks and toys, whereas a classic laser rangefinder can try to suck in the cord from charging the phone.
- 🚀 LiDAR (LDS): Builds an accurate map, works in the dark, ideal for large apartments.
- 🧭 Gyroscope: Moves in flat stripes, but can be lost, cheaper to maintain.
- 👁️ AI-Camera: Recognises objects, requires good lighting, is much more expensive.
Wet cleaning: myths and the reality of technology
Many users still believe that a robot can completely replace a mop. This is a misconception. However, the wet cleaning technology in Xiaomi models has gone far ahead. A basic function known as "wiping" is implemented by a simple rag that vibrates or is statically pressed to the floor.
More advanced models use Y-trend technology or reciprocating, which allows for better drying of dried spots, but the real breakthrough is rotating disk systems and, most importantly, automatic carpet lifting, and if the robot sees the carpet, it picks up a wet cloth to keep the pile from getting wet.
💡
Use only distilled water or special solutions for robot vacuum cleaners. Conventional tap water contains salts that over time clog micro-pumps and nozzles, rendering the wet cleaning module out of order.
And the self-cleaning station models that deserve special attention, not only sucking garbage out of the container, but also washing, drying and pressing rags, transforming the robot from a toy into a full-fledged assistant that requires human intervention only once every few weeks.
| Type of system | Cleaning quality | Carpet lifting | Price. |
|---|---|---|---|
| Static rag | Collects dust. | No. | Low. |
| Vibrational platform | Cleans the stains. | Often not. | Medium |
| Rotating discs | High. | Got it (automatically) | Tall. |
Comparison of popular series: S, M, X and Vacuum
Xiaomi’s lineup of devices and Roborock’s sub-brand (often in the same ecosystem) can be confusing.The Vacuum series usually refers to classic models with a laser, but without the complex washing functions.
The Mijia series (often marked with the letter M) is a middle ground. Here you get great navigation, good battery and basic wet cleaning at an adequate price. For most apartments up to 80-90 square meters, that's more than enough.
The flagship X and Ultra series are technological monsters, equipped with self-service stations, AI cameras and maximum suction power, and it makes sense to overpay for them if you have a complex layout, a lot of furniture on the floor or have pets.
Choice criteria for animal owners
If you have cats or dogs, a normal robot can be a source of stress, and the hair can be wrapped on the brush, and the harsh sounds can be frightening to pets. The basic brush without bristles is critical for these cases. Rubber turbo brushes keep the wool from getting tangled and easy to remove and clean.
The second important aspect is noise level: models with suction power above 4,000 Pa can be quite loud, especially in Max mode. For pets, you'd better choose a model with Quiet Mode or night cleaning when pets are asleep.
⚠️ Warning: Do not leave bowls of water or food on the floor while the robot is running. AI-The camera can accidentally touch the bowl and turn it over, especially if it is lightweight.
Also worth paying attention to is the height of the body, which can be frightened by a tall robot walking on top of it, and in such cases, the "Do Not Disturb" feature in the app, which limits the device to the hours of activity of the pets, helps.
Mi Home Ecosystem and Application Management
Iron is only half the story. The other half is software. All modern robots are controlled through the Mi Home app or Xiaomi Home. The interface allows you to build virtual walls, divide the map into rooms and customize smart home scenarios.
For example, you can set up a scenario where you say, "When everyone's gone, geolocate, launch a robot." Or, "If air quality is down, turn on the cleaner and the robot vacuum cleaner." And integration with voice assistants like Alice, Siri, or Google Assistant is also stable.
☑️ Pre-purchase check
There is a regional nuance, however: Some models designed for the Chinese market may require a region change in the app to "China", which sometimes leads to delays in notifications. RUS boxed.
Maintenance and durability of the device
A robot vacuum cleaner is a maintenance mechanism, and HEPA filters need to be changed every 2-3 months, side brushes wear out in six months, and the main brush and wheels need to be cleaned of hair regularly, ignoring this leads to overheating of the motor and shortened battery life.
Pay special attention to the contacts of the charging station. Over time, they oxidize, and the robot stops charging. Rub them with dry cloth every time you clean the device itself. Also remember to clean the Cliff sensors and bumper, as the dust on them causes navigation errors.
💡
Regular cleaning of sensors and wheels prolongs the life of a robot vacuum cleaner by 2 times. Don't wait until it starts to give out errors, do the TA once a month.
In case of breakdown, it is important to have service centers. Xiaomi’s popular models are easily repairable and parts for them are available on marketplaces even years after the model was released. With niche brands from the same ecosystem (such as Dreame or Viomi), it can be difficult to find original water tanks.
Final recommendations: what to take in 2026
The market has stabilized, and the choices are your priorities. If you have a budget, take a Mijia laser model. If you want perfect dry cleaning and you have carpets, look towards the S series with a turbobrush. For those who want maximum comfort and are willing to pay for no contact with dust, a self-cleaning flagship will do.
Do not chase a record suction power in 6000+ Dad, if you don't have long-pile carpets, you'll have enough for smooth floors and short carpets. 2500-3000 More important is the quality of the algorithms for building a map and the amount of battery.
⚠️ Note: When buying, pay attention to the type of battery. In older or very cheap models, there are still batteries that are difficult to replace. In modern Xiaomi models, the battery is usually removable, but it is better to specify this in the specification.
Remember that a smart home starts with a clean floor, and a well-chosen robot vacuum cleaner will be the most used gadget in your apartment, freeing up time for the really important things.
