Robot vacuum cleaner Xiaomi: what are the differences of models and how to choose

The smart home appliances market today is full of offerings, and it can be extremely difficult to understand them the first time. If you're planning to buy a robot vacuum cleaner, Xiaomi's lineup will seem like an endless maze of numbers, letters and acronyms. Many users get lost in not understanding why seemingly identical devices can cost differently and perform a completely different set of functions.

The main confusion is that Xiaomi is not only made by its engineers, but also by ecosystem partners like Dreame, Roborock and Viomi, which is why you can find devices on store shelves that look almost identical but have radically different algorithms and specifications. Understanding these nuances is the key to saving budget and getting the desired result.

In this article, we will take a closer look at how different generations and series of devices differ so you can make an informed decision, and we will touch on navigation, cleaning and integration in a smart home, because these are the parameters that determine the comfort of use in the long run.

Navigation system: laser, camera or gyroscope

The first and most critical difference to consider when choosing is the type of navigation that determines whether your assistant will randomly scatter around the room, bumping into the legs of chairs, or build an accurate map of the apartment and clean up every inch of space. Old or budget models often have a gyroscope that allows you to move in more or less straight lines, but does not store a map of the room in memory.

More advanced devices use Laser Distance Sensor (LDS) technology, a laser rangefinder located in a characteristic "turret" on the body, which scans the room, creates a digital copy of it and builds the optimal route, which allows it to stay on the base to recharge and continue cleaning from the stop, and work in "kitchen only" or "only around the sofa".

There is also camera navigation (vSLAM), which visually scans the ceiling and walls, and is often found in very low profile models where a laser sensor cannot be built in, but these devices require good lighting and can get lost in complete darkness.

⚠️ Warning: Models with gyros can't build maps in an app, you can't stop them from entering a carpet area or send them to clean a particular room remotely.

When choosing between a laser and a camera, consider the layout of your apartment. Laser models such as the Xiaomi Vacuum-Mop 2 Pro are considered the gold standard for most apartments due to their high accuracy and independence from lighting.

Dry and wet cleaning: types of tanks

The second important classification parameter is the ability of the device to wash floors. Basic models can only vacuum by collecting dust into the main container. However, most modern Xiaomi robots are hybrids that combine the functions of a vacuum cleaner and a mop, and it is important to distinguish between the types of water tanks, because this depends on the quality of wet cleaning.

The simplest option is a mechanical tank, where water is fed to the cloth by gravity or under minimal pressure, which often leads to puddle formation or, conversely, to a dry strip at the beginning of the passage. More advanced systems use an electronic pump that doses water to the napkin depending on the intensity selected in the application.

Flagship models are equipped with a vibrating platform. In such devices, for example, in the Dreame L10s Ultra series or Xiaomi-branded analogues, the rag performs thousands of vibrations per minute, effectively cleaning off old stains, rather than simply wiping the dust, which dramatically changes the result of cleaning on kitchen surfaces.

• 🧹 Mechanical tank: cheap solution, requires water level control, possible leakage.
• 💧 Electronic pump: uniform wetting, adjustment via smartphone, suitable for laminate.
• 🌀 Vibroplatform: imitation of hand washing, better removal of contaminants, high price.

You shouldn’t expect a robot vacuum cleaner to do the perfect floor cleaning as you would after a manual heavy pressure cleaning, but to keep clean between general cleanings, electronic systems do a great job.

Series of devices: Mi, Robot Vacuum-Mop and Pro

Understanding the model names helps you understand the product line. Xiaomi uses several prefixes that indicate the positioning of the device. The base series is often labeled simply as the Xiaomi Robot Vacuum or Mijia Robot Vacuum. These are usually "workhorses" with laser navigation and basic functionality, without the frills like automatic dust unloading.

Vacuum-Mop shows wet cleaning. Name numbers (1, 2, 3) represent a generation. The higher the number, the newer the model, the more sophisticated the algorithms. Pro or Ultra models typically have enhanced suction, a more capacious battery, and additional sensors, such as carpet recognition.

Also worth mentioning are devices developed by partners but sold under the Xiaomi brand. Roborock often creates top-end engineering solutions that can then be released under the Mijia label. It is important to look not only at the name on the box, but also at specific features, as the model range is updated annually.

Autonomy and maintenance of the base

The comfort of using a robot vacuum cleaner depends on how often you have to interfere with its work. The key factor here is the volume of the dust container and the water tank, as well as the availability of an automatic base. Standard models require emptying the container after every 1-2 cleanings, which can be inconvenient for pet owners.

Modern trends dictate the installation of self-cleaning bases, which automatically suck the garbage out of the robot into a large bag that needs to be changed every 1-2 months. Some flagships have gone even further: they automatically fill the robot tank with water, wash and dry the cloth with hot air so that it does not become moldy.

Battery life also varies. Budget models can last 60-90 minutes, after which they require recharging. Advanced devices with high-capacity batteries can clean up to 150-180 minutes, which is enough for 2-3 bedroom apartments even in maximum power mode.

If you choose a model without a self-cleaning base, be sure to check the availability of consumables (filters, brushes) in your area so maintenance doesn’t become a problem.

Smart Functions and Integration into the Ecosystem

All Xiaomi robots are controlled through the Mi Home app (or Xiaomi Home), but the feature set may differ. Basic scenarios such as running on schedule or choosing a cleaning mode are available everywhere. However, advanced models support multi-layer mapping, which is true for two-storey homes.

One of the most useful features is creating virtual walls and no-go zones, so you can color over an area on your phone that the robot is not allowed to enter (such as a place with wires or an animal tray), which in older models may not be available or work properly.

Integration with voice assistants (Alice, Google Assistant, Siri) allows you to control voice cleaning, and support for smart home scenarios, such as launching a robot when everyone is gone, or stopping when the front door is open.

⚠️ Note: To work all the smart features (maps, zones, schedules), Xiaomi servers must be available. In some regions, you may need to install the “China” region or use special methods of connecting.

Update software (firmware) periodically brings new algorithms to bypass obstacles and improve the stability of the connection, so a regular update through the application is mandatory.

Comparative Characteristics Table

To organize the information, let's compare the conventional categories of models that you can find on sale, which will help you quickly navigate the sea of specifications.

As you can see from the table, the difference in price is often due to the presence of a self-service base and type of navigation. For a small studio, a budget model may suffice, whereas for a large house with pets, it is better to look towards flagships.

💡

When buying, pay attention to the height of the case. If you have a lot of furniture with low clearance, a model with a laser sensor ("tower") may not fit there, unlike models with a camera at the top.

Final selection recommendations

Choosing a specific Xiaomi robot vacuum cleaner should be based on your real needs and housing layout. There is no point in overpaying for a vibrator platform and auto-unloading dust if you have a small apartment without carpets and animals. Conversely, saving on navigating in a large space will lead to nervous breakdowns and constant running for a stuck gadget.

The best choice for most users today is mid-range models with laser navigation and electronic pumps, which provide a balance between price and cleaning quality, allowing you to fully automate the process of maintaining cleanliness, flagship solutions are about maximum comfort and minimal human participation.

Remember that even the smartest robot requires a room to be prepared: cleaning the wires off the floor and lifting the curtains if they hang low. Only in tandem with the right training will Xiaomi’s tech show its true potential.

💡

The main criterion for choosing is the type of navigation. Laser (LDS) is mandatory for apartments with complex layout and the presence of many obstacles, as it alone guarantees the construction of an accurate map and a logical route.
