What robot vacuum cleaner Xiaomi is better to buy for an apartment with wet cleaning: the choice of experts

Choosing an automatic cleaning assistant in 2026 has gone from finding a curiosity to scrutinizing technical specifications. Xiaomi’s market and Mijia’s ecosystem offer dozens of models, and it’s extremely easy for a beginner to get confused with acronyms like LDS, LiDAR, and LDS 2.0. The main challenge is finding a device that not only collects dust, but also conducts a quality wet cleaning without turning the floors into wet mess.

Many forum users argue about whether they need an automatic base cleaning function or just a vacuum cleaner with a large water tank. The answer lies in the area of your apartment and the types of flooring. If you have a predominantly laminate or parquet flooring, water dosage requirements become critical. In this article, we will analyze current models available this year and help you decide on your purchase.

And the community's opinion is not to be ignored, because real-world experience often reveals nuances that are not visible in booklets, like the passability of thresholds or the ability not to get stuck on carpets with high pile, and we've analyzed hundreds of discussions and technical tests to give you an objective picture.

The evolution of wet cleaning in the ecosystem Xiaomi

Until a few years ago, wet cleaning in robot vacuum cleaners was about wiping the floor with a barely wet cloth attached to the bottom. Today, technology has gone a long way. Today's flagships use vibration platforms or rotating discs that mimic the movement of a human hand, which allows them to effectively remove dried spots, rather than just smear dirt on the surface.

The key was separation, and the top models learned to automatically raise the washing platform when they hit the carpet so they wouldn't wet it, which was previously only available in the premium segment, but in 2026, these features are also reaching the mid-range, and it's important to understand the difference between a static rag and an active washing system.

⚠️ Attention: Even the most advanced robots will not replace full-fledged cleaning of floors with chemicals in severe pollution.

Intelligent algorithms now allow you to adjust the water supply depending on the type of coating. Electronic control ensures that the tank output will be just as much liquid as the application specifies, which is especially important for owners of combined floors, where tiles and sensitive wood coexist.

Key selection criteria for an apartment

Navigation is paramount when choosing a device for an apartment. The laser rangefinder (LiDAR) remains the gold standard for mapping; it allows the robot to effectively plot routes, avoid hitting furniture, and return to the base for refueling. Models without lidar, working on a gyroscope or chaotic principle, in 2026 should be considered only for very small studios.

The second criterion is the type of detergent: there are systems with one rotating disc, two discs (double vibration) and a retractable cloth. For apartments with a large area, models with automatic base cleaning are better suited, they rinse and dry the mops themselves, which prevents the appearance of unpleasant mold odor.

• 🤖 Navigation: Choose LDS/LiDAR For accurate mapping and construction of virtual walls.
• 💧 Type of wet cleaning: Vibration platform (Sonic) is more effective than static rag.
• 🔋 Autonomy: Batteries with capacity from 5000 That's enough for a m. 150-200 m2 in quiet cleaning mode.

Also (don't ignore) the height of the case. If you have a lot of low-clearance furniture, a tall robot with a lidar tower may not get under the sofa or cabinet, and in such cases, you should pay attention to models with a recessed sensor or camera navigation, although the latter works worse in low light.

Comparison of top models of 2026

Consider the market leaders that are most often recommended on profile forums: first of all, this is the flagship Xiaomi Robot Vacuum X20+ series and the more affordable Mijia 1S. The difference between them is huge: if the first model has a full-fledged self-cleaning station and rising mops, the second offers a basic wipe function.

For pet owners, the Xiaomi Vacuum S10+ or its equivalent is especially relevant, with special brushes that confuse the wool less, and a powerful engine, but if floor washing is the priority, then you should look at devices with hot drying of rags, which prevents the reproduction of bacteria.

When comparing, remember to consider the cost of consumables. Filters, side brushes and rags for different models can cost differently. Original Xiaomi components are usually available, but for rare models, finding them can take time.

Review Analysis: Real User Problems

And by studying forums, you can identify recurring problems that marketers don't talk about, and one of the common complaints is that virtual walls don't work properly, and the robot can ignore restricted areas if they're too narrow, or make a huge hook around them, and that's solved by updating the firmware or reconfiguring the map.

The second common problem is getting stuck in wires and dark corners. Despite the presence of sensors, some models perceive black surfaces as a cliff (step) and go around, leaving dirty stripes along the boards. Dark floors require caution when choosing a model.

⚠️ Warning: Before starting the robot, be sure to remove wires, socks and small objects from the floor. No sensor guarantees 100% protection against entanglement in thin charging cords.

Users also note the importance of regular maintenance: If you don't clean the main roller mechanism of hair, the motor can burn or the cleaning efficiency will fall to zero. Some models have self-untangled brushes, which is a huge plus for owners of long-haired households or pets.

Instructions: Preparing an apartment for a robot

To make Xiaomi's robot vacuum cleaner work as efficiently as possible, you have to prepare your apartment properly. It doesn't require major repairs, but you can't avoid changes (small changes) in your habits. You have to organize the floor space first.

Start by cleaning the wires. Use cable channels or just raise them higher. Then assess the thresholds between the rooms. If the height difference is greater than 2 cm, the robot may not overcome it, and you will have to carry it manually or build ramps. For wet cleaning, it is important that the floor is pre-cleaned of large debris.

Recommended sequence of actions:


1. Remove small objects from the floor.




2. Hide the dangling curtains and tablecloths.




3. Close the doors to the "dangerous" areas (bathroom, toilet).




4. Pour water into the tank and start building the map.

After the first cleaning, make sure to check the map in the app, divide it into rooms, name them, and set no-go zones around animal water bowls or around computer desks with wires, which will take 10 minutes, but save hours of your time in the future.

💡

Use magnetic tape (if supported by a model) or virtual walls to enclose the area around the animal feeder so that the robot does not sprinkle food and stain the bowl with water.

Service and extension

The durability of the device depends on the quality of care: the HEPA filter must be changed every 2-3 months, and the main brush must be cleaned of hair after each cleaning. Remember to wash the dust container and especially the dirty water container in the self-cleaning base to avoid odor.

For wet cleaning, use only distilled water or reverse osmosis water. Tap water contains salts that quickly clog the nozzles and leave white plaque on the floor and inside the system, which is critical to maintaining the guarantee and performance of the pump.

• 🧹 Brush: Cleanse your hair and threads weekly.
• 💧 Water tank: Change water daily, don’t leave it in the tank overnight.
• 🔋 Contacts: Wipe charging contacts on the robot and base with dry cloth.

Check the wheels regularly for hair wounds. If the wheel stops spinning, the robot will start spinning in place and report an error. Simple prevention once a week will extend the life of the machines for years.

💡

Using distilled water is the only way to prevent scale from forming in the water supply system and keep the floor clean without dilution.

Final verdict: what to choose?

So to sum up, there's no perfect robot, there's a perfect choice for your environment. If you're on a budget, you can take a model with a self-cleaning base and a mop lift, which is 2026 comfort level. If you're on a budget, a Mijia with laser navigation would be a great compromise.

The key is not to expect a miracle from cheap models with chaotic traffic. For a wet apartment, systematic and intelligent route construction is important. Investment in good navigation will pay off with saved nerves and clean floor.

Now you know which robot vacuum cleaner Xiaomi is best to buy for a wet apartment, judging by the forums and technical data. Choose wisely, given the peculiarities of your home.
