Choosing a smart home cleaning assistant is a challenge due to the sheer number of models released under the Xiaomi brand and its sub-brands. The market is crowded with devices that look similar, but radically different in navigation, suction power and wet cleaning functionality. A user looking for an answer to the question of which robot vacuum cleaner is better, encounters dozens of items where the price difference can reach several times, and visually distinguish a budget from a flagship without studying the specifications is impossible.
The key factor in 2026 was not just suction strength measured in Pascals, but the intelligence of the navigation system and the quality of the algorithms for building a room map. Laser rangefinder (LiDAR) has become the standard even for the mid-range segment, displacing chaotic motion and gyroscopic navigation from top-end lines. However, even among laser models, there are significant differences in scanning speed, accuracy of circumventing obstacles and the ability to save several floor maps.
In this article, we will discuss in detail the technical nuances that are hidden behind the beautiful names of models, and help determine what configuration is necessary for your type of housing. We will not just list the characteristics, but explain how they affect the actual operation of the device in a Russian apartment with carpets, wires and furniture of complex shapes.
The evolution of navigation: why sensor type is more important than power
The first thing to look at is navigation, because it determines cleaning efficiency and speed. Older models that use a gyroscope move like snakes, often skipping corners or getting stuck in one place. Modern flagships use LiDAR navigation, which allows you to scan a room in 360 degrees and build an accurate map in real time, which gives the device the ability to clean rooms sequentially without losing orientation even with a discharged battery.
But there is a gradation among laser systems. Budget models can have one static laser that is worse at handling low obstacles, such as sills or chair legs. Top-end devices like the Xiaomi Robot Vacuum X20+ series or the Dreame L20 Ultra (Xiaomi ecosystem) are equipped with additional depth sensors and AI-recognition cameras, which allow the robot to see wires, socks and toys by going around them rather than getting entangled in them.
It's important to understand the difference between navigation and obstacle recognition. A laser maps walls and large furniture, but it doesn't see small objects on the floor. Only models with a front camera and structured light can identify the type of object, such as a carpet from a linoleum or a cable from a plinth. If there's a lot of stuff scattered in the house, the savings on this module will lead to constant stuckness and the need to save the robot.
When choosing a model for a multi-storey house or apartment with redevelopment, the ability to save several cards is critical. Budget versions often allow you to store only one card, which forces the robot to re-scan the room every time the base moves to another floor. Advanced algorithms in the Mi Home application allow you to save up to 4 cards, automatically recognizing the floor by the location of the charging station.
Wet cleaning: from a simple rag to a vibrating wash
Wet cleaning has gone from a simple rag attached to the bottom to complex systems with automatic washing and drying. In 2026, the standard for quality cleaning has become a vibrating wash, where a platform with a rag makes reciprocal movements, simulating hand friction, the only way to remove parched stains that a normal rag hose simply can’t handle.
The most advanced models, such as the Xiaomi Robot Vacuum X10+ or Mijia 1S, are equipped with self-cleaning stations. After cleaning, the robot returns to the base, where the detergent modules are automatically washed with clean water and the dirty one is drained into a separate tank. Some models even know how to dry rags with warm air, preventing mold and unpleasant smell, which is a common problem when hand washing.
Special attention should be paid to the automatic lifting of the carpet. If there are carpets with a long pile in the room, the robot must either bypass them or lift the detergent module to avoid wetting the textiles. The lifting mechanism can be mechanical or hydraulic, and its presence significantly increases the cost of the device, but for mixed floors it is a necessary condition for comfortable operation.
And don't forget water consumption. Smart dosing systems only deliver water to the cloth when you're driving and depending on the mode you're in (economical, standard, intense), which avoids puddles on the floor and excessive laminate wetness. In cheap models, water can simply drip by itself, which can damage the flooring.
Comparison of top models: characteristics and features
To make it easier to choose, we've compiled a comparison table of current models, which shows key parameters that affect cleaning quality and usability. Note that the suction power is in Pascals (Pa), and for most tasks, values of 4,000 Pascals or higher are sufficient.
| Model | Type of navigation | Power (Pa) | Wet cleaning | Self-cleaning |
|---|---|---|---|---|
| Xiaomi Robot Vacuum X20+ | LiDAR + Camera | 6000 | Vibro wash + lift | Yeah (washing/drying) |
| Mijia Robot Vacuum-Mop 2 Pro+ | LiDAR (LDS) | 3000 | Electronic pump | No. |
| Dreame L20 Ultra | dToF + AI Camera | 7000 | Vibro wash + hot water | Yes (full cycle) |
| Xiaomi Vacuum E10 | gyroscope | 4000 | Gravitational | No. |
The Xiaomi Robot Vacuum X20+ represents a middle ground for most users, combining powerful suction, an efficient carpet-lifting vibration wash, and a full self-service station, which is capable of fully autonomously serving an apartment of up to 80-100 square meters for a month without human intervention.
For owners of large, complex homes and spaces, the Dreame L20 Ultra series is a better option, and its advanced object recognition and hot water floor washing make it the best quality machine in the final result, but the price of such a device can be two to three times higher than that of the basic laser models.
Mi Home Ecosystem: Management and Automation
The hardware is only half the success. The other half is the software and the Mi Home mobile app, which is where virtual walls are set up, cleaning schedules and filter monitoring are monitored. The app interface allows you to create rooms, name them, and set each room to its own cleaning mode, such as Quiet for the bedroom at night or Maximum for the kitchen.
Smart home integration allows you to start cleaning according to scenarios. For example, a robot can start working immediately after you leave the house (geolocation of the smartphone), or after a smart outlet fixes the vacuum cleaner shutdown. Voice control via Yandex Alice, Google Assistant or Siri (via HomeKit) adds another level of convenience, allowing you to start cleaning with a voice command.
⚠️ Note: For all functions, including voice control and scripting, the application server must be selected correctly. For devices purchased in Russia, the “Russia” region is usually suitable, but some global versions may require changing the region to “China” or “Singapore”, which can complicate integration with local assistants.
The app also provides a cleanup history and a map of contamination, where the color indicates the places with the most dust, which helps to identify problem areas and, if necessary, increase the frequency of cleaning in specific rooms. Regular updates to firmware through the application often bring new algorithms and bug fixes, so it is recommended to keep the software up to date.
Maintenance and durability: what to look for
Buying a robot vacuum cleaner is an investment that requires proper maintenance to maintain its effectiveness over the years. The main consumables are HEPA filters, which trap fine dust and allergens. They need to be changed every 3-6 months depending on the dustiness of the room and the availability of pets. The use of washable filters is possible, but their resource is significantly lower than that of the original replacement ones.
The main brush is also prone to wear. The bristles wear off over time and hair winds up on the ends, which can lead to engine jamming. Many modern models are equipped with bristles-free (silicone) brushes that are easier to clean and more efficient at harvesting wool. The side brushes serve less than the central ones and often require replacement every six months, as their pile quickly loses elasticity.
Wheels and bearings are another node that needs attention, often stuffed with dust and wool, which creates resistance and increases the load on the batteries, regular cleaning of wheel niches and lubrication of bearings (if necessary) will prolong the life of the undercarriage, and it is also worth checking the status of the charging station contacts, the oxidation of which can lead to problems with charging.
The battery degrades over time, and battery life decreases. On average, lithium-ion batteries last 2-3 years of active use. The advantage of popular Xiaomi models is the availability of spare parts on the market, which allows you to replace the battery or motor yourself without resorting to the services of a service center.
Budget vs. flagships: is it worth overpaying?
The question of whether to buy an expensive device is always relevant.Budget models like Xiaomi Vacuum E10 Mijia 1C, They do a great job of collecting dust and fine debris on flat surfaces, and if you have a small apartment, no high-pile carpets and no animals, you overpay for self-cleaning functions. AI-The camera may not make sense.
But if you think of cleaning as a way to free up time, flagship models benefit from being completely autonomous. The ability to not take out the trash for a month and not wash the rags by hand changes the user experience dramatically. Vibro washing in expensive models really wipes away stains, while public sector workers only slightly dust off, leaving divorces.
Cost of ownership is also worth considering: A cheap robot may require more frequent replacement of filters and brushes because of a less efficient filtration system that allows fine dust into the engine. Expensive models often have better sealing and filtration systems, which prolong the life of the engine.
