What is the difference between Xiaomi vacuum cleaners: a complete guide to lines and technologies

Choosing cleaning equipment in the Xiaomi ecosystem often turns into a difficult quest due to the huge number of sub-brands and models that visually can seem the same. At first glance, all devices look stylish, minimalistic and offer smart management, but the technical content can vary dramatically depending on the price segment. Understanding these differences is critical, since overpaying for unnecessary functions or, conversely, saving on key characteristics can spoil the impression of owning a gadget.

The main confusion is that Xiaomi often acts as an investor for a variety of startups such as Dreame, Roborock and Viomi, branding their designs or selling them under its own name. The key difference lies not only in the logo on the case, but also in the engines used, the types of navigation and the quality of air filtration. In this article, we will discuss the architectural and functional features so you can choose the device that will solve your cleaning tasks.

It’s worth noting that the fundamental difference between wireless vertical models and Xiaomi’s robot vacuum cleaners is the autonomy and depth of carpet cleaning, which is often overlooked when you first get acquainted with the range. If you’re planning a purchase, you need to clearly prioritize whether you need total robot autonomy or high suction power of a handheld device to quickly clean local contaminants.

Architecture of brands: Xiaomi, Dreame, Roborock and Viomi

The first thing a customer needs to understand is the structure of the Smart Home ecosystem from the Chinese giant. Devices sold under the Mi Home brand or just Xiaomi are often basic versions or the result of collaborations. For example, popular models of robot vacuum cleaners with the letter “S” in the name are often produced by Dreame Technology, which specializes in high-speed engines.

Roborock, in turn, has historically been responsible for top-end models with advanced navigation and laser rangefinder (LDS), although in recent generations the boundaries have blurred somewhat. Viomi often focuses on integration with smart kitchen appliances and specific features such as wet cleaning with ultrasound. The difference between these manufacturers within the Xiaomi ecosystem is the software and the available algorithms for building a room map.

⚠️ Note: When choosing a management app, make sure the model supports your region in the Mi Home app.Some devices released for the domestic Chinese market under sub-brands may require a region change to China, which slows down the server response.

It's also important to distinguish between the intended purpose of the lines. If Dreame relies on powerful suction and turbo brushes to prevent hair wounding, Roborock often implements better navigation and obstacle avoidance systems.

Navigation technologies: LDS, VSLAM and gyroscopes

The most significant difference in price between Xiaomi’s robot vacuum cleaners is in the navigation system. Budget models, often labeled “Gyro” or “Planning,” use gyros and accelerometers to plot their route, move in a snake-like manner, but do not create an accurate map of the room, and can get lost when they interrupt, starting cleaning again.

The middle and upper segments are equipped with a laser rangefinder (LDS) that is in a characteristic round thickening on the body. These devices scan the room, build an accurate floor plan in the application and allow you to set virtual walls. More advanced models, such as the flagship Xiaomi Vacuum X or the top-end Roborock, use a combination of LDS and artificial intelligence cameras to recognize objects (cables, socks, shoes).

There's also VSLAM technology, which uses a camera to navigate in space. It works worse in total darkness, but it does a great job in well-lit, complex-plan apartments. The difference in cleaning efficiency between gyroscopic and laser navigation is enormous: if a laser robot takes 95% of the area in one pass, a gyro robot can skip corners or get stuck, requiring human intervention.

• 🔹 Gyroscopic navigation – chaotic movement, no map, suitable for studios up to 40m².
• 🔹 LDS (Laser) – accurate map, division into rooms, work on schedule, zone cleaning.
• 🔹 AI + Camera - recognition of the type of pollution, bypassing obstacles, working in the dark (with IR illumination).

When choosing a model, pay attention to the height of the laser sensor. In some versions of Xiaomi, the sensor is made flatter, which allows the device to go under low furniture, but this may slightly affect the angle of view in rooms with very complex terrain. For most standard apartments, the difference is not noticeable, but for homes with many rapids and narrow passages, this can be a decisive factor.

Filtration systems and air quality

For allergy sufferers and families with young children, the difference between Xiaomi vacuum cleaners can be critical in the filtration system: Basic versions are often equipped with simple mesh filters that trap large dust but let fine particles and allergens back into the air. More expensive models are equipped with a multi-stage cyclone filtration system in combination with the HEPA-filter E11 or E12.

The vertical models of the Xiaomi G9, G10 or Dreame V11/V12 series use cyclone technology, where air spirals and dust falls into the glass under centrifugal force without clogging the filter instantly. Robot vacuum cleaners often use a simpler scheme where the filter is the main barrier, which requires more frequent cleaning.

Some flagship models, like the Xiaomi Robot Vacuum X10+ or Dreame, offer self-cleaning stations, which have a powerful motor that sucks dust from a robot container into a large bag in the base. This dramatically changes the experience of using: you don't have to come into contact with dust for weeks. The difference in noise levels between a self-cleaning station and a conventional vacuum cleaner is also significant - the bases work louder, but shorter.

⚠️ Attention: Never wash HEPA-water filters unless explicitly stated in the instructions that they are washable, 90% of the time the water destroys the microfibers, and the filter loses its properties, turning into a regular cloth that allows dust to pass through.

Suction power and engine types

One of the main marketing metrics that buyers look at is suction strength, measured in Pascals (Pa) or Aerowatts (AW). Xiaomi’s lineups show a clear gradation: budget models offer about 2000-2500 Pa, medium ones - 3000-4000 Pa, and top-end devices such as the Dreame V12 or Xiaomi Vacuum G10 Plus reach 5000 Pa and above.

But dry numbers don't always reflect reality. The difference is the efficiency of the engine. Modern models use brushless motors that can reach speeds of up to 125,000 to 150,000 rpm. The high speed of rotation creates the thinning necessary to pull dust from the depths of the carpet pile, while simple models only collect surface debris.

It is important to consider that maximum power is only available in Turbo or Max mode, which quickly lands the battery. In the automatic mode that most users use, the difference between the model 2500 Pa and 4000 Pa may not be so noticeable on hard floors (laminate, tile), but will become apparent on the carpet. For owners of long-pile carpets, having a powerful motor is a must.

• 🔸 2000-2500 Pa - enough for smooth floors and collecting wool from the surface.
• 🔸 3000-4000 Pa - the gold standard, copes with medium-fat carpets and large garbage.
• 🔸 5000+ Pa – professional cleaning, knocking dust from the depths of textiles and carpets.

Also worth noting is the difference in noise. The more powerful engines in new Xiaomi models often work quieter thanks to improved body aerodynamics and quality bearings, whereas the older powerful models could buzz like a jet on takeoff. Engineers learned to balance power and acoustic comfort.

💡

When choosing a vertical vacuum cleaner, pay attention to the weight of the main unit (motor pipes). If it exceeds 1.5 kg, cleaning high curtains or ceiling webs will quickly tire your hand, regardless of the power of the motor.

Autonomy and types of batteries

Energy saving is a hot topic, especially for owners of larger apartments or houses. The difference between models often lies in the capacity and chemical composition of batteries. Older or budget models can be equipped with elements with a lower capacity (2000-2500 mAh), which provides 20-30 minutes of maximum power.

Modern flagships such as the Xiaomi Vacuum G11Dreame V16 use batteries with a capacity of up to 3000-4000 mAh or more, and also support fast charging. The key difference is also the possibility of a removable battery. In some Xiaomi models, the battery is non-removable, and if it degrades in 2-3 years, the device will have to be carried into service or discarded. In more sophisticated models, the battery can be removed and replaced by yourself in a minute.

For robot vacuum cleaners, not only is battery size important, but the logic of return to base. Smart room map models (LDS) can interrupt cleaning, return to charging, and then resume from the same place. Cheap models without a card when discharged simply turn off, and you have to manually carry them to the base and re-start them, hoping that they do not go off the route.

Full charging times also vary: Standard models charge around 3-4 hours, whereas fast charging technologies can restore capacity to 80% in just 1.5-2 hours, which is critical if you use a vacuum cleaner several times a day or live in a large apartment that requires recharging during a single general cleaning.

Wet cleaning function: vibration and pressure

Many Xiaomi models are positioned as 2-in-1, combining dry and wet cleaning. However, there is one of the biggest differences. Basic robots simply put a rag on the floor under their own weight. This helps remove light dust, but does not wash away the dried stains. More advanced models, such as the Xiaomi Mop 2 Pro series or Dreame Bot, use vibration platform technology (Sonic Mopping), which makes up to 3,000 vibrations per minute, simulating hand movements.

Even higher up are downforce robots, which lowers the platform with the rag more when it detects the carpet (to avoid wetting it), or presses it against the floor for better launderability. Xiaomi vertical vacuum cleaners are also evolving in this direction, with separate tanks for clean and dirty water, and a self-cleaning function for the brush with hot water, which prevents smearing of dirt.

⚠️ Warning: Even if the model supports wet cleaning, never add household chemicals or chlorine to the water tank unless explicitly authorized by the instruction.Aggressives destroy pump seals and can cause electronics to break, and also cancel the warranty.

Notable for this is the spray mops that have been introduced in Xiaomi's lineup recently, which don't just wipe the floor, they spray the cleaning solution in front of the brush and suck in the dirty water immediately, the difference between the cleanup and the usual wet wipe, like the sky and the ground, especially in the kitchen or in the hallway.

Comparative table of popular series

To organize information, let's summarize the major differences in a single table, and that helps you navigate quickly through a sea of names and indexes.

As you can see from the table, the difference between models within a category can be as great as between different device classes, and the choice of a particular model should be based on your real needs, not just on an attractive price or a recognizable logo.

💡

Main conclusion: Do not chase the maximum performance. For an apartment of 50 m2 with laminate enough basic LDS-robot, while for a house with carpets and a dog, a powerful vertical vacuum cleaner with a HEPA-filter.
