Robot vacuum cleaner Polaris or Xiaomi: what to choose in 2026?

Choosing an automatic home cleaning assistant often turns into a difficult dilemma, especially when the time-tested Xiaomi brand is on one side of the scale, and the actively developing Polaris. Both manufacturers offer a wide range of modern technologies, but their philosophy and approach to the implementation of functions differ significantly. The user needs to clearly understand what tasks he assigns to the device, so as not to overpay for unnecessary options or, conversely, not to face the limitations of basic functionality.

The robotics market is oversupplied, and it's almost impossible to understand technical specifications without diving deep into specifications. Suction strength, type of navigation, water tank volume and ecosystem integration are just the tip of the iceberg. In this article, we'll do a detailed analysis to help you determine which robot vacuum cleaner will be better at handling your specific living conditions, whether it's a carpet apartment or a pet house.

Importantly, the comparison will be done not only in terms of dry numbers, but also in terms of the actual user experience. We will touch on reliability, availability of supplies and software quality, as these aspects often determine the final impression of the purchase. The key difference is ecosystem integration: Xiaomi offers a deep connection with the Mi Home, while Polaris relies on independence and versatility.

Navigation and mapping technologies

The fundamental difference between modern robots is the way they navigate. Xiaomi models, especially the Roborock series and more advanced versions under their own brand, traditionally use a laser rangefinder (LDS), which allows you to build an accurate map of the room, effectively plan the route and avoid repeat trips to already cleaned areas. Laser sensor scans the room 360 degrees, which provides high accuracy even in complete darkness.

Polaris, in turn, takes different approaches across price segments. Budget models often rely on gyroscopic navigation or chaotic movement with collision sensors. However, the brand’s flagship lineups also feature laser-based mapping devices that may be as good as competitors in mapping quality. Chaotic navigation significantly increases cleaning time, as the robot can repeatedly return to the same corners while skipping others.

And you have to consider that mapping quality has a direct impact on zoning, and advanced algorithms allow you to divide the map into rooms, virtual walls, and no-go zones, and if you're only critical to cleaning in a certain area, like around a pet tray or under the dining table, having an accurate map becomes a requirement, and in this regard, the leaders of the segment offer the most flexible customization tools.

💡

When choosing a robot with a gyroscope, make sure there is enough lighting in the room, as some optical sensors may not work properly in the dark.

The difference is clear: while one brand is committed to maximum automation and intelligent space analysis, another offers solutions focused on ease of use without complex settings. For large apartments with complex layouts, laser navigation is the only choice for efficiency and speed.

Suction power and quality of cleaning

One of the main parameters that buyers are paying attention to is the suction force, measured in Pascals (Pa). Xiaomi in its mid- and upper-end devices often shows rates from 2500 Pa to 5000 Pa and above. This power allows you to efficiently remove dust from the depths of the pile of carpets and collect large debris from hard coatings. The engines in these models are usually high energy efficiency and low noise.

The Polaris range also includes powerful devices, but in the budget segment, the figures can be more modest, ranging from 1500 to 2000 Pa. This is enough to support daily cleanliness on smooth surfaces such as laminate, tiles or linoleum. However, for homes with more carpeting or owners of molting animals, more serious traction may be required to avoid getting stuck in the brushes.

• 🌀 Type of brush: Combined brush (slat) + rubber) better collects wool without winding it, unlike purely pile counterparts.
• 🔋 Impact on the battery: Maximum suction power significantly reduces battery life, reducing the area of retractable territory.
• 📉 Adjustment: The possibility of automatic power increase on carpets is not all models, which is important to consider.

The quality of cleaning in corners and along walls also depends on the design of the side brush and the shape of the body. Some models have a shifted main brush or additional side brushes, which allows better dust removal from hard-to-reach places. The efficiency of filtering out air also plays a role, especially for allergic people, so the presence of a high-quality air conditioning system is also important. HEPA-High-end filters are a big plus.

Wet cleaning: functionality

Having a wet cleaning function has become the de facto standard, but the implementation of this option is radically different from one manufacturer to another: In the basic models of both brands, the most common passive humidification system is a system where water flows spontaneously to the cloth through micropores in the bottom of the tank, which is only suitable for light surface refreshment, but is not able to wash off dried stains or sticky traces.

More advanced Xiaomi models and top-end Polaris devices are equipped with electronic water supply. In such systems, the pump adjusts the amount of liquid supplied to the floor cloth, which avoids puddles and stains. Water level management is often carried out through a mobile application, where you can choose the intensity for different types of coatings. This is especially true for mixed floors, where carpet and tile are combined.

Special attention should be paid to robots with vibrating or rotating discs. Mechanical surface action allows you to remove more pollution by mimicking the movements of the human hand. If you want to know how to wash floors, not just wipe dust, you should consider models with such improvements, because a regular rag dragging on the floor often only smears dirt.

⚠️ Note: Do not use a wet carpet robot unless the design includes an automatic rag lifting system or a removable module.

The volume of the water tank also matters: the larger it is, the more area the robot can process without refueling. On average, the tanks can hold 150 to 300 ml, which corresponds to 60 to 100 square meters of area depending on the chosen moisture mode. For large apartments, the presence of an increased volume tank or a self-cleaning station will be the decisive factor.

Smart home and mobile applications

The ecosystem and software are the brains of your robot. Xiaomi is setting industry standards here using the Mi Home or Xiaomi Home platform. The app lets you not only run the cleaning, but also build detailed maps, set schedules, adjust power and track the history of cleaning. Moreover, Xiaomi devices easily integrate with voice assistants like Alice, Google Assistant and Siri, creating a single network of smart homes.

Polaris robot management applications like Poliris Home or Tuya Smart (depending on the model) are also functional, but may be inferior in interface polish and depth of settings. However, they often benefit in simplicity: the user does not need to create a region-specific account, which is sometimes required for Xiaomi devices. For those who value independence from the manufacturer's servers and want to manage the equipment locally, this can be an important advantage.

Connectivity stability is an important aspect: Robots running over cloud servers may lose connectivity when they encounter Internet problems, while locally controlled devices continue to execute commands over the LAN. Automation scenarios, such as running house cleaning when all family members leave home, are available in both ecosystems, but require fine-tuning in universal applications.

Autonomy and maintenance

The operating time on a single charge depends on the battery capacity and the chosen power mode. The average for modern models is from 90 to 150 minutes. This time is usually enough to clean an apartment with an area of 100-120 square meters. An important feature is the ability to automatically return to the base for recharging and continue cleaning from the stop, which is important for large areas.

Robot vacuum maintenance requires regular attention. Maintenance of hair and wool, sensors and wheels, and filters are wiped off. Xiaomi often uses standardized consumables that are easy to find on the market, but they can be more expensive than their counterparts. Polaris spare parts are also available, but depending on the specific model, finding original components can take longer.

Below is a comparative table of key characteristics of typical representatives of both brands:

⚠️ Before the first full-fledged cleaning, be sure to conduct an audit of the room: remove wires, socks and small objects from the floor that the robot can tighten inside the mechanism.

Summary comparison and recommendations

To sum up, the choice between Polaris and Xiaomi depends on your priorities. If you already own Xiaomi smart home devices and want to get the most integrated solution with advanced navigation algorithms, Xiaomi (or Roborock sub-brand) will be the most logical choice.

If you want a powerful machine with good functionality, but you don't want to be stuck in one ecosystem or you're looking for better value for money, Polaris offers decent alternatives, and they often have bigger batteries or water tanks at the same price point as their competitors.

Remember that even the smartest robot requires space preparation, regular maintenance and proper operation will extend the life of the device regardless of the brand you choose. Ultimately, the clean floor is the result of the work of the technology, but the competent choice of model makes this process invisible and enjoyable.

💡

For apartments with complex shapes and many obstacles, priority should be given to models with laser map construction (LDS), regardless of the brand.
