The modern smart appliance market is full of offers, but when it comes to robot vacuum cleaners, the Xiaomi brand and its sub-brands (Roborock, Dreame, Viomi) remain the undisputed leaders. Consumers often face the dilemma of overpaying for a flagship model or choosing an affordable option that will do just as well.
In this article, we will take a closer look at what kind of robot vacuum cleaner you want to buy if you want to clean your floors properly, and we will look at key technologies, compare current models, and make honest recommendations based on performance and real-world experience, and choosing the right one will save you nerves and money in the long run.
Before we go into specific models, we need to understand what marketing terms mean. Many users mistakenly assume that all devices are washed the same way, but the difference between a simple simulated wash and a real hygienic cleaning is huge. Understanding these nuances will help you avoid disappointment after buying.
Key Wet Cleaning Technologies from Xiaomi
The main difference between low-cost and advanced models is the water supply system, the simplest versions use a passive system where water flows by itself through a cloth, which often results in uneven moisture: the floor is filled at the beginning of the harvest, and the floor is dry at the end. More advanced solutions are equipped with electronic water control, which allows you to adjust the intensity directly from the application.
Flagship models like the Roborock S7/S8 series or the Dreame L10/L20 use vibration or rotating disc technology. Vibration allows dried spots to be wiped off by mimicking hand movements with a rag, and disc elements provide circular scrub cleansing. This is critical for tile and linoleum, where mechanical action is required.
Special attention should be paid to the carpet lifting system. If you have carpets in your home, the robot must either bypass them or lift the detergent module to avoid wetting the pile. In medium- and high-end models, it has an intelligent lift of several millimeters, making the device versatile for mixed floor types.
- 🌊 Electronic pump: Accurate dosage of water, excludes puddles and dry bald spots.
- 🔄 Vibration platform: High frequency vibrations for removal of complex contaminants (VibraRise technology).
- 🤖 Automatic lift: Carpet sensors force robot to lift mop on 5-15 mm.
⚠️ Attention: Passive water supply system (gravitational) is categorically not suitable for a low-moisture resistance laminate, since there is a high risk of overmoisturizing the joints.
Navigation: Why LiDAR is more important than a gyroscope
Cleaning efficiency depends on how well the robot builds the route. Budget models often have a gyroscope or chaotic navigation, which can allow them to skip areas or wander for a long time in search of a base. For quality wet cleaning, LiDAR navigation (laser rangefinder) is critical, which builds an accurate map of the room.
With a map, you can actually use virtual walls and zoning, you can stop a robot from entering a particular room, or you can just send it to the kitchen after cooking, and without a map, these functions don't work properly or are not available at all, making a smart device a toy.
In addition, modern route-making algorithms allow robots to avoid returning to areas that have already been washed away, saving battery life and time, especially for large apartments where one charging cycle may not be enough for the entire area when driving chaoticly.
Can we do without a map?
When choosing a model, pay attention to the height of the laser sensor. Too high "towers" can prevent the device from entering low furniture, leaving dust there. Xiaomi engineers are constantly working to reduce the size of the sensors, maintaining their accuracy.
Comparison of popular series: Roborock, Dreame, Viomi
Xiaomi’s ecosystem includes many brands, and it’s not easy for a beginner to understand them. Roborock is traditionally considered a premium segment with the best algorithms and reliable build. Dreame offers aggressive pricing and often introduces innovations (such as mop self-cleaning) before competitors. Viomi and Mijia occupy the niche of affordable solutions with good basic functionality.
If you prioritize perfect wet cleaning, you should look at models with base self-cleaning function, which automatically rinse and dry the cloth after each pass or after cleaning is completed, which saves the user from contact with dirt and prevents the unpleasant smell that is inevitable when hand washing rags.
The table below compares the key characteristics of current models so that you can quickly decide on the choice:
| Model | Type of navigation | Feature of wet cleaning | Autonomy |
|---|---|---|---|
| Roborock S8 Pro Ultra | LiDAR + 3D | Vibration + Carpet lift + drying | 180 minutes |
| Dreame L10s Ultra | LiDAR + Camera | Rotating discs + hot drying | 210 minutes |
| Xiaomi Robot X10+ | LiDAR | Rotating discs + auto-dolling | 150 minutes |
| Viomi V3 Max | LiDAR | Y-shaped trajectory, electronic pump | 150 minutes |
💡
For families with children and animals, models with a self-cleaning base (Ultra-series) are the most hygienic choice, as they exclude contact with dirt.
The influence of the type of flooring on the choice
The choice of robot vacuum cleaner depends on what the floor in your apartment is covered with. For ceramic tiles and porcelain, models with rotating discs or powerful vibration are ideal, since these surfaces require active mechanical action to remove contaminants in the seams.
If you have laminate or parquet, you have to prioritize humidity control, and you have to have carpet sensors (which work like elevation sensors) and a precise electronic pump, and excess water can blow up the laminate, so you better get around the models without water level adjustment.
Owners of combined coatings (tile in the kitchen/corridor, laminate in rooms) should pay attention to hybrid solutions, such robots are able to recognize the type of coating (though not always perfect) or allow you to set different cleaning scenarios for different rooms through the application.
- 🏠 Tile/Stone: Requires high friction force and abundant (but controlled) moisture.
- 🪵 Wood/Laminate: Needs minimal water and fast drying.
- 🧶 Carpets: Require mop lifting or automatic zone bypassing.
⚠️ Warning: Even if the robot (states) is safe for laminate, it is recommended to pre-check your coating's response to moisture in an inconspicuous place by setting a minimum water supply level.
App and smart home: control from the phone
All modern Xiaomi robots are controlled through the Mi Home or Xiaomi Home app. The interface allows you to adjust the suction force, water supply level, build virtual walls and set a schedule. It is important that the application server is chosen correctly (often for devices from China or Europe you need to change the region).
Integration with a smart home opens up additional possibilities: you can customize the script: "When I leave the house, the cleaning starts" or "After cooking in the kitchen, the robot washes the floor." Voice control through Aliice, Google Assistant or Yandex Station (through integration) adds another level of comfort.
Cleaning maps, history and service settings are also available in the app, and regular firmware updates can improve obstacle avoidance algorithms and washing efficiency, so keep the device up to date.
Some advanced features, such as object recognition (cables, socks, toys), require data processing that can be done both on-device and in the cloud. A stable connection to Wi-Fi (2.4 GHz band) is a must for all smart functions to work.
Maintenance and durability of the detergent module
Buying a robot is just the beginning, and in order for the device to last and clean the floor, it needs to be taken care of. The main consumable is a microfiber wipe, which needs to be washed regularly and changed periodically (every 3-6 months), as the pile wears out and loses its ability to hold dirt.
It is important to keep the sensors and wheels clean. Sand and hair wrapped on brushes and axles can damage the mop lifting mechanisms or cause sensor errors. Regular cleaning of the main dust container and water tank will prevent mold and unpleasant odor.
If you use detergents, choose only specialized liquids for robot washers. Conventional household chemicals can contain foaming components that will disable the pump, or aggressive substances that destroy plastic and rubber seals.
☑️ Weekly service
Timely maintenance not only prolongs the life of the device, but also ensures that cleaning quality remains high even after a year of active operation. Neglecting to clean the sensors often leads to the robot becoming dull and crashing into obstacles.
Recommended recommendations: how not to make a mistake when buying
To sum up, the ideal wet-cleaning robot should combine precise navigation, smart water supply and ease of maintenance, and avoid chasing the cheapest model if you're looking for real help around the house rather than a toy.
When you choose, consider the availability of LiDAR navigation, the ability to build maps and, if possible, the availability of a self-cleaning station, if budget allows, which radically change the experience of interaction with machinery, making the cleaning process truly automatic.
Remember that a robot vacuum cleaner is a tool for keeping clean, not cleaning heavily polluted rooms. Regular use (every day or every other day) will give a better result than rare but intense sessions.
💡
When buying, pay attention to the availability of consumables (wipes, filters, side brushes) for a particular model in your area, so as not to face maintenance difficulties.
