The modern smart market offers many solutions for cleaning automation, and Xiaomi is at the forefront. Choosing a wet cleaning model may seem like a simple process, but the variety of features often puts the buyer at a loss. You need to clearly understand the difference between basic features and advanced technologies, so as not to overpay for unnecessary options or, conversely, not to buy a device that will not cope with your tasks.
In this article, we will take a closer look at the key parameters to look for when choosing a smart assistant from the Chinese giant: navigation, carpet type, control through the application and the quality of materials – all of which affect the final result. A properly selected device will save you tens of hours of free time and ensure cleanliness in the house without your intervention.
Before you get to the technical details, you need to prioritize, some people want to navigate the complex layout perfectly, others want to be able to wash their floors without getting divorced, and understanding your own needs is the first step to making a successful purchase.
Type of navigation and map construction
One of the most important criteria for choosing a navigation system is how efficiently a robot moves around the apartment and can clean in the dark. Most modern Xiaomi models have a laser rangefinder (LDS) on top of the housing, which scans the room, builds an accurate map and allows the device to clean systematically, strip by strip, not chaotic.
There are models with camera-based navigation (VSLAM) or gyroscope. Camera robots can see obstacles perfectly, but can get lost in total darkness because they need light. Gyroscopic models build a less accurate map and often require human presence for initial adjustment or operate in zigzag mode without saving the map in memory. For full wet cleaning, laser navigation is better, because it allows you to specify virtual walls and exclusion zones.
⚠️ Note: Models without lidar (LDS) They may be worse at wet cleaning in larger apartments, as they cannot effectively divide the room into zones and return to the dock to refuel the water in the tank.
The smartphone app is the control center for the whole process, and through it you get access to an interactive map where you can:
- 📱 Install virtual partitions for areas where the robot should not enter (for example, a long-pile carpet).
- 🗺️ Divide the map into rooms for selective cleaning of specific areas.
- 🚫 Create forbidden zones around animal bowls or wires.
Importantly, the interactive map is stored in the device's memory, allowing the robot to know the layout even after recharging, especially for large homes where one charge may not be enough for the entire cleaning, the robot will return to base, recharge and continue to work from where it left off.
Design of the wet cleaning module
The quality of floor washing depends on the design of the module attached to the bottom of the robot. The Xiaomi and Roborock ecosystem (sub-brand) use different approaches. The basic version is a plastic platform with a water tank and a mount for a microfibre rag. Water is supplied by gravity or through a simple pump, which often leads to uneven moisturization.
More advanced models are equipped with an electronic pump that regulates the water supply to within a milliliter, which allows you to choose the intensity of humidification through the application: low for light dust, medium for daily cleaning and high for dried stains. Having electronic water management is a critical parameter for a quality wash.
Why is an electronic pump important?
And the vibrating platform models that we're looking at are not just sliding across the floor, but they're doing high-frequency vibrations that help to clean up pollution more effectively, and that brings the quality of the robot cleaning up closer to the effortless hand wash.
For apartments up to 60 square meters, a tank of 150-180 ml is enough, but for large areas it is better to look for models with a tank of 250 ml and above, which will allow wet cleaning throughout the apartment without having to add water in the process.
Suction power and types of carpets
Although the main focus of the article is wet cleaning, the suction power cannot be ignored. The robot must first collect dry dust and debris before wiping the floor. If not, the dust will mix with water and turn into dirty porridge that will be difficult to remove. Modern Xiaomi models offer suction power from 2000 to 5000 Pascals.
For carpet owners, having a carpet sensor is critical, and when the robot comes in, it has to automatically:
- 🔇 Increase the suction power for deep cleaning of the pile.
- 💧 Turn off the water supply so as not to wet the carpet.
- 📈 In some models, lift the wet cleaning module (Carpet Boost function).
If you have a lot of long-pile carpets in your house, you should consider models that can completely uncouple the rag or lift it by a few millimeters. Conventional models can simply bypass the mats if they are listed as a no-go zone, but automatic identification of the type of coverage is the premium segment level.
The suction power also affects the noise of the device, and at maximum speeds, even expensive models can make quite a lot of noise, but in Quiet or Night mode they work almost silently, allowing you to start cleaning even at night or while watching TV.
Battery autonomy and management
The surface area of the retractable surface depends on the capacity of the battery. Standard models can remove from 50 to 80 square meters on a single charge in maximum power mode. If you have a studio apartment or a small "two", this will be enough. For larger areas (100+ sq.m.), you need a more capacious battery or the function of continuing cleaning after recharging.
The important parameter is the running time. On average, Xiaomi robots last 90 to 150 minutes in standard mode. When Turbo is activated, the operating time can be reduced by half, so you should always pay attention to the declared operating time in the mode that you plan to use most often.
| Parameter | Budgetary models | Mid-segment | Flagship models |
|---|---|---|---|
| Battery capacity | 2600 mAh | 3200mAh | 5,200 mAh |
| Time to work. | 90 minutes | 120 minutes | 180 minutes |
| Return to base | On discharge. | On discharge. | Auto-charging and continuation |
| Cleaning area | up to 60 m2 | up to 100 m2 | up to 250 m2 |
Auto Recharge & Resume is the standard for middle- and high-end, and the robot knows that it runs out, drives to base, charges up to 80 percent, and returns exactly where it left off, and without that, large apartments will be able to clean up their devices manually.
Passability and dimensions of the device
The geometry of the robot plays an important role, especially if you have a lot of furniture. The height of the device should be less than the distance from the floor to the bottom of the sofa or cabinet. The standard height of Xiaomi models with lidar is about 9.6-10 cm. This allows them to go under most modern sofas, but you can have problems with low beds or tables.
Wheel diameter also affects cross-country ability. Larger wheels allow you to cross thresholds up to 2 cm high and go on carpets with a high pile. Small wheel models can get stuck at the junctions of tile or get entangled in the fringe of the carpet. Notice the presence of wheel suspension, which ensures tight contact of the brush with the floor even on uneven surfaces.
⚠️ Attention: Laser rangefinder (LDS) If you are critically interested in getting the robot under very low furniture (less than 9 cm), consider models without top lidar (with navigation). VSLAM gyroscope, but consider their navigation limitations.
Clearance is also important: If the robot is too low, it can suck in small objects lying on the floor or get stuck on thick carpets. Optimal clearance allows the main brush assembly to fit tightly to the surface without losing ground.
Services and supplies
Buying a robot is just the beginning, and in order for the device to last long and clean properly, you need to maintain it regularly, especially the main brush, the side broomstick, the HEPA filter and the wet cleaning cloth, and the availability and price of consumables is an important economic factor.
Xiaomi and Roborock models are easy to find consumables, as they are popular brands. However, for the more rare sub-brands of the ecosystem (for example, Dreame or Viomi), components may cost more or have to be ordered from abroad. Always check the availability of filters and brushes in local stores before buying a particular model.
☑️ Daily maintenance of the robot
The fine cleaning filter (HEPA) requires regular replacement, usually every 2-4 months, depending on the dustiness of the room. If not, the suction power will fall, and the motor may overheat. The floor rag must be washed after each wet cleaning, so as not to spread dirt around the house and prevent the appearance of unpleasant odor.
Comparison of popular series
Xiaomi and partners’ robot vacuum cleaners are extensive. Model names can be difficult to understand, and can be divided into several categories. The budget series (often labeled Mijia or Xiaomi Vacuum without additional letters) offers basic navigation and simple wet cleaning.
The Roborock series is considered the gold standard, with the best mapping algorithms, a high-quality electronic water pump, and powerful suction, a choice for those who want to get the most functionality and are willing to pay for it.
The Dreame sub-brand (L10, L20, etc.) often offers innovative features at a more affordable price, such as the ones that used to have automatic base washing and drying functions, which now has migrated to other lines, and the choice between these brands often comes down to affordable budgets and stock availability in stores.
💡
When choosing between models from different years of release, choose a newer model, even if the characteristics seem similar. Newer versions usually improve the algorithms for avoiding obstacles and optimize power consumption.
When choosing a particular model, pay attention to the year of release. Technology is developing rapidly, and a model three years ago can significantly inferior to the novelty in the speed of mapping and object recognition.
