Choosing an automatic cleaning assistant has become a challenge in today’s world, with the sheer number of models on the market. Xiaomi’s robot vacuum cleaner has been leading the way for years, offering the best value for money. If you’re looking for a device that not only collects dust, but also cleans the floors, you need to understand the intricacies of navigation and tank types.
In this article, we will make a detailed comparison of current lines so you can understand which robot vacuum cleaner Xiaomi is best for a wet house. We will look at the differences between mapping systems, suction power and, most importantly, the effectiveness of floor washing algorithms.
The focus is not just on suction characteristics, but also on the design of the water tank, which is what determines whether the floor will be left with divorces or clean. Current models of the Mijia and Roborock ecosystem offer completely different approaches to this problem, from simple gravity to ultrasonic vibration.
Selection criteria: navigation and types of wet cleaning
The first thing to look at when choosing a navigation system is the budget models often use chaotic motion or a gyroscope, making quality wet cleaning impossible, since the robot simply does not know where it has already been. LDS-Navigation (laser rangefinder) or more advanced vSLAM (camera) allow you to build an accurate map of the room. Without an accurate map, the robot will miss areas or, conversely, rub one place for too long, leaving puddles.
The second critical parameter is the water supply mechanism. Simple models have a passive tank where water flows through the fabric. This often leads to uneven moisture: at the beginning of the harvest, there is a lot of water, and at the end of the cloth is already dry. More advanced systems use an electronic pump that doses water with high accuracy, ensuring that the wipe is stable throughout the cleaning.
⚠️ Warning: Never pour hot water or water with aggressive cleaning agents into the robot vacuum cleaner water tank unless explicitly authorized by the instructions.This can damage the pump membrane or cause internal elements to corrosion.
The most modern solution is vibration washing technology. In devices like the Xiaomi Vacuum-Mop 2 Ultra series, the napkin makes thousands of reciprocal movements per minute. It allows you to wipe off dried stains, which is impossible to make a conventional static rag. It's also worth paying attention to the possibility of automatically lifting the carpet so that the robot does not wet the pile during wet cleaning.
Top budget models: functionality for reasonable money
If you're getting into smart appliances for the first time or your budget is limited, you should pay attention to the entry level. Xiaomi Robot Vacuum E10 or Mijia 1C are popular options that can build a map, but have restrictions on wet cleaning. These models use a passive tank where water is fed by gravity. This is normal for keeping clean, but it won't help to wash old contaminants.
A more interesting option in the budget segment is the Xiaomi Vacuum-Mop Essential. This model already has electronic water control, which is rare for this price. The robot can adjust the humidity level through the Mi Home app, choosing between low, medium and high levels. However, it does not have a laser rangefinder, navigation is carried out through the camera, which requires good lighting.
- 📉 Pros of public sector: affordable price, the presence of a basic card, management from a smartphone, quiet work.
- 📈 Cons: weak suction force compared to flagships, lack of auto-lift rags, passive or simple electronic water supply.
- 🔋 Autonomy: usually enough to 90–110 minutes, which is enough for an apartment to 60-70 square-meter.
For small studio apartments or one-room rooms budget models with LDS-They're able to collect wool and dust efficiently, and wet cleaning is going to be a light refresher, and the key is not to expect them to be the perfect wiping of kitchen fat.
💡
When buying a budget model, be sure to check the availability of spare filters and side brushes in the kit or their availability on sale, as consumables will have to be changed every 3-6 months.
Mid-segment: Balance of price and technology
The golden middle of the market is represented by the Xiaomi Vacuum-Mop 2 and 2 Pro series. This is where the real quality cleaning begins. The key difference is the presence of a laser rangefinder LDS and, in some versions, the Y-shape function (moving along a trajectory resembling the letter Y for better corner washing). Models with the Pro or Plus prefix often equipped with sonic technology, where the wipe vibrates 3,000 times per minute.
This class of devices has a smart logic of operation, and it understands the difference between carpet and hard surface, and when it's wet, it can either bypass carpets, or if it has an electric valve, automatically lift the water and cloth module a few millimeters, a critical feature for combined-coated homes.
| Model | Type of navigation | Suction force (Pa) | Type of wet cleaning |
|---|---|---|---|
| Mijia 1S | LDS (Laser) | 2000 | Electronic pump |
| Vacuum-Mop 2 | LDS (Laser) | 2200 | Electronic pump |
| Vacuum-Mop 2 Pro | LDS (Laser) | 3000 | Sonic (Vibration) |
| Vacuum-Mop 2 Ultra | LDS + Camera | 4000 | Sonic + Auto-Lift |
An important aspect of the mid-range is the integration with the smart home. You can create scenarios where the robot starts cleaning when you leave the house, or stops if sensors detect an obstacle. The Mi Home app allows you to create virtual walls and exclusion zones, which is especially true for wet cleaning, so that the robot does not go into areas with carpets or children's play on the floor.
💡
Mid-size vibratory sink (Sonic) models can handle 90% of household pollution in the kitchen and hallway, making the purchase of expensive self-cleaning stations optional for most users.
Flagship solutions: self-cleaning stations and advanced washing
The top of evolution is self-cleaning robots like the Xiaomi Robot Vacuum X10+ or Mijia S10, which don't just wash the floor, they serve themselves. The base automatically shakes the dust out of the robot into a big bag, and also washes and dries the rags, and you only have to throw out the dust bag once a month and put the water in a clean tank once a week.
The flagship models feature double rotating floorwashing discs, and unlike the vibration platform, the two round rags rotate at high speed, simulating hand movements when washing the floor. The pressure on the floor in these models is much higher, which allows you to remove even dried stains from coffee or juice. AI-Recognition allows the robot to bypass wires, socks and other small objects that can get stuck in conventional models.
Another unique feature of the top models is the automatic addition of detergent, and there's a special compartment in the database where the concentrate is poured, and the robot doses it itself, depending on the regime and the area of cleaning, which provides disinfection and better removal of fat without the risk of spoiling the flooring with excess chemistry.
⚠️ Note: When using a self-cleaning base with hot air drying, make sure the robot is installed in a well-ventilated place. Humidity in a closed cabinet can cause mold to appear on the base elements.
The cost of these complexes is high, but it pays off with minimal human input, and in fact, you just start cleaning with your voice or schedule, and all the dirty tasks (contact with dust and dirty rags) are taken over by the machinery, which is ideal for large houses, pet owners and people with allergies.
The Hidden Possibilities of Self-Cleaning Bases
Navigation comparison: LDS vs vs. vSLAM and gyroscope
Understanding the type of navigation is key to deciding which robot to buy for your home. Gyroscopic navigation is the cheapest option. The robot moves in straight lines, pushing against the walls. The map is either not built at all or is built very conventionally. For wet cleaning, it's a bad option: a robot can miss the whole corner of a room or, conversely, drive around one place ten times.
LDS-The Laser Distance Sensor uses a rotating laser rangefinder on the top panel, and it scans the room 360 degrees to create a very precise plan, and the robot knows where each chair and leg of the table is. This allows him to build the optimal route, not to fight against furniture and wash the floors in smooth parallel strips, which guarantees no passes.
vSLAM (Visual Simultaneous Localization and Mapping) uses a camera that is usually located in the front or top. It "sees" the ceiling and objects, determining its position. Pros vSLAM: the robot is lower in height and can go under low furniture where LDS will not fit. Cons: requires good lighting, in the dark, efficiency drops, and on mirrored surfaces navigation can fail.
- 👁️ LDS: Operates in complete darkness, very accurate map, but requires a place on top (height about 10 cm).
- 📷 vSLAM: Low body, sees obstacles in the face, but depends on light.
- 🌀 Gyroscope: Cheap but chaotic, not recommended for complex layouts.
For high-quality wet cleaning, it is definitely worth choosing models with LDS. Only laser navigation provides the sequence of movements that is necessary for uniform wetting and wiping of the floor. Chaotic movements of public sector workers lead to the fact that some areas of the floor are washed three times, while others remain dry.

Management and integration into the smart home ecosystem
All modern Xiaomi robots are controlled through the Mi Home app (or Xiaomi Home), the interface allows you not only to start cleaning, but also to zone the room. You can divide the apartment into rooms, name them and set your own mode for each, for example, in the kitchen set maximum suction power and intensive washing, and in the bedroom – quiet mode and only easy wiping.
An important function is to create virtual walls and exclusion zones, and on an app map you draw a red line or a square, and the robot will never cross that border, and this is indispensable for wet cleaning, you can prevent the robot from entering the living room carpet or the area where children's toys are scattered, and you can create areas of increased cleaning, where the robot will go twice or make zigzag movements.
Integration with voice assistants Aliice, Google Assistant and Yandex Alice (through skill) allows you to control voice cleaning. The phrase "Alice, turn on the robot in the kitchen" will start the device in the desired area. This is convenient when your hands are busy, or if you need to quickly remove spilled liquid before it dries.
⚠️ Warning: When you first set up the robot, be sure to update its firmware through the app. Often manufacturers release updates that improve the algorithms for mapping and fix pump bugs that were in the factory version.
