Robot vacuum cleaners Xiaomi has long ceased to be exotic — today it is a full-fledged assistant in cleaning, able to replace the traditional vacuum cleaner in 80% of cases. But the range of the brand is so wide that it is difficult to understand it without preparation: here and budget models for 15 thousand rubles, and flagships with laser navigation for 60+ thousand. What is the difference between the series Mi Robot, Dreame and Viomi? Why is one model worth 2 times more than another, although at first glance differs only in color? And what key parameters are really important when choosing?
In this article, we will take a closer look at Xiaomi’s current line of robot vacuum cleaners, compare them on 10 criteria, from navigation to wet cleaning support, and give specific recommendations on which model to choose for an apartment, a house with animals or a large cottage.
1. The main lines of robot vacuum cleaners Xiaomi: who is who
Under the Xiaomi brand, three main families of robot vacuum cleaners are produced, which differ not only in price, but also in the approach to development:
- 🔹 Mi Robot is a classic lineup developed directly by Xiaomi, and it's a collection of time-tested laser navigation models (LDS), Minimalist design and deep integration with the Mi Home ecosystem, ideal for those who value stability and do not pursue innovation.
- 🔹 Dreame is a premium-focused sub-brand of Xiaomi, where you will find the most powerful suction modules (up to 4000 Pa), advanced navigation systems (including the most powerful suction modules). 3D-Scanning and unique features like automatic cleaning mode change. Dreame often becomes a test site for technologies that later appear in Mi Robot.
- 🔹 Viomi is another sub-brand, but with a focus on design and multifunctionality. Viomi models often come with custom options (such as a UV lamp for disinfection or automatic brush lifting), and their body is made in a more “home” style than the strict Mi Robot.
It’s important to understand that all three brands share a common platform (for example, many models run on the same Cortex-A7 processor), but differ in firmware, hardware and feature set. This means that even a budget Mi Robot can be more reliable than some Viomi models of the same price segment – it all depends on the specific task.
2. Navigation systems: laser vs camera vs gyroscope
One of the key parameters that determines how efficiently a robot cleans your home is the type of navigation, and here Xiaomi offers three basic approaches, each with its pros and cons.
| Type of navigation | Principle of work | Pluses | Cons | Example of models |
|---|---|---|---|---|
| Laser rangefinder (LDS) | Scans the room with a laser beam, builds a map in real time | ✅ Accuracy to 1 cm✅ Works in the dark.✅ Supports zoning | ❌ More expensive than other solutions❌ May be blinded in the sun or reflections | Mi Robot Vacuum-Mop 2 Pro, Dreame D9 |
| Camera (VSLAM) | Oriented by visual labels (ceiling, furniture) | ✅ Cheaper than a laser.✅ It works well in daylight. | ❌ Lost in the dark❌ Problems with mirrors and monochromatic walls | Viomi V3, Mi Robot Vacuum-Mop Essential |
| Gyroscope + sensors | It moves along a random trajectory, focusing on obstacles. | ✅ The most budgetary option✅ Simplicity of construction | ❌ Chaotic cleaning❌ Longer cleaning.❌ No room map. | Mi Robot Vacuum 1S, Redmi Robot Vacuum |
In practice, laser navigation is the most reliable solution, but it is only relevant for apartments with complex layouts (many rooms, corridors, steps). If you have a studio or a one-bedroom apartment, it makes no sense to overpay for LDS, so can the camera. But gyroscope models should be considered only as a second vacuum cleaner to maintain cleanliness between general cleaning.
💡
If your apartment has a lot of mirrors or glass partitions, avoid models with camera navigation (VSLAM) – they will constantly “lost” from the route.
3. Suction power: myths and reality
Manufacturers like to specify the maximum suction power in the pascals in the characteristics of robot vacuum cleaners (Pa). On paper, the difference between 2000 Pa and 4000 Pa seems huge, but in practice it is not so clear.
- 🌀 Real efficiency depends not only on power, but also on turbine design and brush density. D10 Plus with 4000 Pa can yield in cleaning the wool Mi Robot Vacuum-Mop P with 2500 Pa, if the latter has a better side brush.
- 🔋 Turbo mode is rarely used in practice - it quickly drains the battery and creates unnecessary noise. 90% In some cases, the robot works 60-70% maximum capacity.
- 🧹 Type of garbage: for dust and small litter will be enough 1500-2000 Pa, and for animal wool or large debris (for example, children's crackers) need a reserve of 2500 Pa+.
The more important thing to look at is the type of filter. Budget models often have the usual filter type. HEPA-A filter that is clogged in 2-3 months and needs to be replaced. Z10 Pro) a cyclone filter is used, which lasts for years and better retains allergens.
💡
Suction power is not the main criterion. Much more important is the design of the brushes, the type of filter and the cleaning algorithm, for example, a robot with 2,500 Pa and a good side brush will collect the wool more efficiently than a model with 4,000 Pa, but a weak turbine.
4.Wet cleaning: which models really wash the floor
Almost all modern Xiaomi robot vacuum cleaners are positioned as 2-in-1 devices – vacuum and wash.
- 💧 Passive system (platform cloth): found in most budget models (Mi Robot Vacuum-Mop 2 Lite). The cloth is simply wetted and dragged on the floor - efficiency is minimal, suitable only for fresh spots.
- 🌊 Active system with vibration: the cloth vibrates, simulating manual cleaning (Dreame) D9, Viomi V3). It can wash dry spots, but requires frequent water replacement.
- 🧼 Electric pump system: water is supplied at dosed pressure (Dreame) Z10 Pro, Mi Robot Vacuum-Mop 2 Pro. The most efficient option, but also the most expensive.
The key thing is that the robot is not going to replace the mop in principle, and the best it can do is keep the floor clean between general cleanings, if you have laminate or tiles, an active system with vibration is the best choice, and if you have flooring or expensive linoleum, you'd better limit it to dry cleaning or use a minimum water supply regime.

5. Autonomy and operating time: how much the robot will work without recharging
The autonomous operation time of the robot vacuum cleaner depends on three factors:
- Battery capacity: in budget models there is a battery for 2000-2600 mAh (enough for 60-90 minutes), in flagships - 5200 mAh (up to 180 minutes).
- Cleaning mode: at maximum power (4000 Pa), the robot will discharge 2-3 times faster than in eco-mode (1000 Pa).
- Area and type of coating: the robot uses more energy on the carpet than on the laminate, and the number of obstacles (the more there are, the more often the robot maneuvers and lands faster) also affects the number of obstacles.
In practice, for an apartment of 50-70 m2, a robot with a 2600 mAh battery (for example, Mi Robot Vacuum-Mop 2 Lite) will be enough. For large houses (100 m2 +), you need a battery from 5200 mAh (Dreame D10 Plus) or support for automatic refueling (the robot itself returns to the base, recharges and continues cleaning).
Store the robot on the base at a temperature of 15-25 ° C
Do not leave it empty for a long time.
Use eco-mode for regular cleaning
Clean the charging station contacts 1 time per month
Avoid cleaning at maximum capacity without needing to-->
6 Intellectual functions: what is really needed and what can be done without
Xiaomi’s modern robot vacuum cleaners are packed with smart chips, but many of them turn out to be marketing tricks, including what features are worth overpaying and what are easy to do without:
| Function | Appointment | Do I need it? | Example of models |
|---|---|---|---|
| Zoning | Dividing the apartment into zones with different cleaning settings | ✅ Yes, if you have different coatings (carpet/laminated) | Mi Robot Vacuum-Mop 2 Pro, Dreame D9 |
| Voice assistant | Manage via Alice, Google Assistant or Siri | ❌ No, that's enough of an app. | All models with Mi Home support |
| Automatic emptying of the container | Robot unloads garbage to the station after cleaning | ✅ Yes, if you have allergies or animals | Dreame D10 Plus, Viomi V3 Pro |
| 3D-scanning (ToF) | Determines the height of obstacles (does not run on the mat) | ⚠️ Useful, but not critical. | Dreame Z10 Pro |
| UV lamp | UV-disinfected floor | ❌ No, the effectiveness is questionable. | Viomi V2 Pro |
The most useful feature to pay for is automatic emptying of the container, which not only saves time, but also reduces the amount of allergens in the air (especially for families with children or pets), but the UV lamp or voice control is more marketing than real benefit.
💡
If you have pets, look for models with fecal recognition (like the Dreame D10 Plus) that bypass the pets' surprises without smearing them on the floor.
7.Compatibility with Xiaomi ecosystem: what you need to know
All Xiaomi’s robot vacuum cleaners work through the Mi Home app (or Dreame Home for Dreame models), but there are a few nuances:
- 📱 Region-specific: Some models (e.g. Mi Robot Vacuum-Mop 2 Pro) are officially sold only in China.
- 🔄 Firmware updates: Dreame robots get updates more often than Mi Robot, but sometimes new firmware versions break stability (for example, after an update, the robot can start to “hang” in corners).
- 🤖 Integration with other devices: The robot can automatically turn on when everyone leaves home (via Mi Home Automations) or sync with smart sockets to recharge.
If you plan to use the robot in conjunction with other Xiaomi gadgets (for example, smart lamps or motion sensors), choose models that support Mijia Mesh - they are better integrated into the ecosystem.
💡
Before buying a Xiaomi robot vacuum cleaner, check if it supports your region in Mi Home.Some Chinese models may require you to create a new account with a China-based connection, which is inconvenient for Russian users.
8 Which model to choose: recommendations for different tasks
In order not to get confused in dozens of models, we have prepared specific recommendations based on your needs:
- 🏡 Apartment 50-70 m2, laminate / tile: Mi Robot Vacuum-Mop 2 Lite - optimal price / quality ratio, laser navigation, wet cleaning.
- 🐶 House with animals: Dreame D10 Plus – powerful suction (4000 Pa), automatic emptying, recognition of excrement.
- 🏠 Large house 100m²+: Dreame Z10 Pro - battery 5200 mAh, 3D-scanning, multi-card support (you can save a plan of several floors).
