The modern smart appliance market is oversaturated with offerings, but it is Xiaomi’s brand and its sub-brands (Roborock, Dreame, Viomi) that set the standards for quality and functionality. When a user asks which robot vacuum cleaner Xiaomi should choose, they often encounter a confusing nomenclature of models where the numbers and letters in the title are not always obvious. From entry-level budget decisions to AI flagships, the choice depends on a variety of factors, including flooring type, availability of pets and space.
The biggest mistake in buying is focusing on price or suction power, and the type of navigation and the quality of the mapping algorithms are really key, and that's what makes the device randomly scatter around the room or methodically clean every inch of the floor, and in this article, we'll take a look at the nuances so you can make an informed decision.
It's important to understand that the Mijia ecosystem has dozens of devices under one control, but not all models work equally well with voice assistants or support complex automation scenarios, so prioritize before buying: do you just need dry wool cleaning or a full-fledged floor wash with disinfection?
The evolution of navigation: from gyroscope to LiDAR
The first thing to look at when choosing is the navigation system, which determines the intelligence of the device. Budget models often have a gyroscope or even run chaoticly, which is acceptable for studios, but catastrophically small for apartments over 40 square meters, in which cases the robot can skip lots or get stuck in the same places.
The gold standard today is a laser rangefinder. LDS (The Laser Distance Sensor, which is located in a distinctive drum on the top panel, scans the room 360 degrees to create an accurate map. More advanced flagships use LiDAR technology, or a combination of laser sensors with cameras and structured light, to recognize small objects such as wires, socks or toys.
If you choose a model without a laser rangefinder, be prepared for it to run slower and less efficiently.Camera Navigation (vSLAM) also shows excellent results, but requires good lighting and clean camera lens.
⚠️ Note: Models with eye navigation or gyros often don’t know how to build permanent maps in an app, which means you can’t stop them from entering certain areas or putting them in a room to clean.
The difference in price between a chaotic cleaner and an LDS model can be twofold, but the difference in experience is tenfold. You stop being a "guard" who constantly saves a stuck device, and you can delegate the cleaning to the technician completely.
Dry and wet cleaning: myths and reality
Many users are looking for a two-in-one device, expecting the robot to vacuum perfectly and clean floors to shine. The reality is that wet cleaning is very much dependent on the type of design. Basic models will just put a cloth behind them, which is only good for removing fresh dust, but not for removing dried stains.
More advanced systems use a vibration wash (as in Xiaomi Robot Vacuum-Mop 2 Pro+ models) or rotating discs. Vibration simulates the movement of a hand with a cloth, effectively erasing dirt. Flagship stations can also automatically lift carpets to avoid wetting them, or even wash the cloth itself in a hot water base.
Water tank volume also matters. For apartments up to 60 sq.m. enough tank for 200 ml, but for large areas it is better to choose models with electronic water control or combined tanks, where water is supplied dosed, preventing the formation of puddles.
⚠️ Warning: Never pour hot water, chlorine-containing products or foaming detergents into the robot vacuum cleaner tank, which will corrosion the pump, break down the rubber seals and cause the device to fail, which is not a warranty.
If you have a lot of long-pile carpets in your house, the wet cleaning function can be a problem. Make sure that the model you choose can automatically unfasten the module with the cloth or lift it, otherwise the carpet will be hopelessly spoiled.
Autonomy and self-service bases
The current trend is to minimize human involvement in the cleaning process, whereas before the robot required attention after each run (shake the container, wash the cloth), now there are Auto-Empty and Auto-Wash stations, and the dust dumping bases allow you to forget about the container for 30-60 days, sucking garbage into a large bag.
Top stations can also automatically wash and dry rags with hot air, which is critical to preventing odor and bacteria from spreading, and Hot Air Drying is a feature worth looking for first if you plan to use washing mode actively.
Battery capacity also plays a role. For a standard apartment, it is enough 3000-4000 mAh, which allows you to clean 1-2 times. For houses with an area of more than 100 square meters. and complex layouts, it is better to focus on batteries from 5000 mAh so that the robot does not return to recharge in the middle of the room.
☑️ Criteria for choosing a self-service base
These are expensive, but they're a game-changer, and you can go on vacation for two weeks and then you can get clean floors back, but remember, these systems require regular replacements of consumables, dust bags, filters and cleaning solutions.
Comparison of popular series and models
To avoid confusion, consider the main lines, which can be divided into budget, middle class and premium, and the table below compares the key characteristics that will help you decide on your choice.
| Series/Model | Navigation | Suction force | Wet cleaning | For whom? |
|---|---|---|---|---|
| Xiaomi Essential / Basic | gyroscope | up to 2,500 Pa | Passive (rag) | Small apartments, studios. |
| Robot Vacuum-Mop 2 Lite | LDS (Laser) | 2200 Pa | Electronic filing | Optimal budget choice |

The Lite series often lacks some smart home features, but offers a full-fledged laser. Pro models typically have a more powerful motor and improved obstacle-detection algorithms. Sub-brand flagships often offer technologies that are later introduced into Xiaomi's core lineup.
When choosing between brands within the ecosystem (like Roborock vs. Dreame), the difference often lies in the software and build quality of the main nodes. Roborock is famous for reliability and better algorithms, and Dreame often offers richer functionality for less money.
⚠️ Note: Pay attention to the region of the device version (Global) when buying, CN, EU). Chinese versions (CN) You may have problems connecting to servers in your region or voice control in Russian without additional router settings.
Smart management and integration into the ecosystem
All modern robots are controlled through the Mijia app (or Xiaomi Home), which allows you to build virtual walls, set no-go zones and clean schedules, and it is important that the app supports splitting the map into rooms, which allows you to send the robot to clean only the kitchen after cooking.
Integration with voice assistants Alice (Yandex), Siri (HomeKit through the gateways) or Google Assistant adds comfort. You can say, "Alice, wash the floor in the kitchen," and the robot will execute the command. However, this feature requires a stable Internet and the correct setting of accounts.
The No-Go Zone feature is critical if you have animal bowls, wires or fragile objects on the floor at home. Laser models build these zones very precisely, while gyroscopic models can err by a few centimetres, sometimes resulting in stuckness.
Secrets of setting up virtual walls
Maintenance and durability of machinery
Buying a robot vacuum cleaner is not a one-off action, but the beginning of a relationship with a device that requires care. The main enemy of any technology is hair and wool that is wound on a brush. Even the best models with anti-entanglement brushes require cleaning every 1-2 weeks.
HEPA filters need to be knocked out regularly, changed every 3-6 months. A clogged filter reduces suction force and overloads the engine. The side brushes also wear out and start to pick up debris from angles worse.
To prolong the life of sensors (especially laser rangefinder and drop sensors), they must be periodically wiped with dry soft cloth. Dust on the sensors can cause the robot to “blind” and start to move or fall down stairs randomly (if you have a two-level apartment without rapids).
💡
Extend battery life: If you're away for a long time and don't plan on using the robot, disconnect it from the grid and turn off the switch (if any) or leave it at a base with a charge level of 50-60%. Storing a fully discharged or fully charged lithium-ion battery is harmful.
