Why compare Redmond and Xiaomi?
Choosing a robot vacuum cleaner is now a quest: dozens of models, conflicting reviews, marketing promises. The market leaders are always Redmond and Xiaomi, brands that offer gadgets with optimal value for money. But which is better: Xiaomi’s time-tested ecosystem with its smart algorithms or Redmond with an emphasis on power and simplicity?
This article will not just list specifications. We will look at real-world use cases where each brand exhibits its strengths and weaknesses. For example, did you know that Xiaomi robots are better at navigating in complex apartments, and Redmond often wins in price at comparable suction power? Or that models with laser rangefinders (LDS) can hang in bright sunlight if not configured correctly?
We analyzed 15 popular models from 2023 to 2026, reviewed feedback from owners (including negative ones), and conducted our own tests, resulting in a guide that will help you choose a robot vacuum cleaner for specific tasks, whether it is cleaning pet hair, washing floors or working in a large house.
1.Suction power: myths and reality
Manufacturers like to give sky-high power figures of 2500-4000 Pa. But in practice, these values say little without context. For example, a robot with 2000 Pa can collect dust more efficiently than a model at 3000 Pa, if it has better brush design or sealing system.
Redmond traditionally relies on high power: their flagships (for example, Redmond RV-R650) offer up to 3,500 Pa. However, in tests on long-pile carpets, such models do not always meet expectations - a powerful airflow can simply "blow" dust on the sides if there is no proper adjustment.
Xiaomi, by contrast, often uses adaptive algorithms: the Mi Robot Vacuum-Mop 2 series automatically boosts power when it detects heavy pollution, saving battery power and reducing noise. But there’s a nuance: in maximum power mode (2,700 Pa), some Xiaomi models start to bounce on high carpets due to insufficient pressing.
- 🔋 Redmond: High power out of the box, but requires manual adjustment for different coatings.
- 🤖 Xiaomi: “smart” power adjustment, but may not cope with deep-grained dirt.
- ⚠️ Important: power above 3000 Pa is only relevant for homes with carpets or allergies. 1500-2000 Pa is enough for laminate / tile.
Navigation and mapping: who won’t get lost in your apartment?
Navigation is the brain of a robot vacuum cleaner, where Xiaomi has traditionally led the way thanks to LDS technology and complex mapping algorithms. Models like the Xiaomi Robot Vacuum-Mop 2 Pro not only remember layouts, but also allow:
- 🗺️ Divide the apartment into cleaning areas (for example, "living room" and "kitchen").
- 🚫 Prohibit cleaning in certain places (baby cot, pet food).
- 🔄 Up to 5 floors (relevant for private homes).
Redmond uses simpler gyro navigation or visual sensors (cameras) in most models, which are cheaper but have disadvantages:
- 🌀 Robots can be lost in large areas (area) > 80 m m m m²).
- 🌞 Cameras do not work well in bright light (sun rays create glare).
- 🔄 The cards are not saved between cleaning (you have to build again).
The exception is the flagship model of the Redmond RV-R650 with LiDAR, but it costs almost like the top Xiaomi, losing the sense of economy.
What if the robot is constantly beating on furniture?
| Parameter | Xiaomi (LDS) | Redmond (gyroscope/camera) |
|---|---|---|
| Map accuracy | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ |
| Working in the dark | ✅ Yes. | ❌ No (cameras need lights) |
| Keeping the map | ✅ Yeah (multi-room) | ❌ No (builds again) |
| Price. | It's 30 to 50 percent more expensive. | Budgetary |
3. Battery and operating time: how long will it last without recharging?
The average time of a robot vacuum cleaner is 90 to 150 minutes, but the actual autonomy depends on:
- 🔋 Battery capacity (standard - 2600-5200 mAh).
- 🏠 Apartment area and type of coverage (carpets plant battery faster).
- 🔊 Mode of operation (maximum power reduces time by 30-40%).
Xiaomi typically equips its models with 5200mAh batteries (like the Mi Robot Vacuum-Mop 2 Ultra), which lasts 180 minutes in standard mode. Redmond often saves: even in models for 30 000 ₽ You can find a battery for 2600 mAh, which is only enough for 60-80 minutes.
Critical: battery degradation: after 2-3 years, the capacity drops by 20-30%, and the robot begins to “distance” to the base. Xiaomi has the advantage of supporting fast charging (for example, 100% in 3 hours versus 5-6 hours in Redmond).
⚠️ Attention: if the robot often does not reach the base, check the location of the charging station. The optimal distance is no more than 8 meters in a straight line, without obstacles.
4.Floor washing function: should you overpay?
Robot vacuum cleaners with floor washing function is a separate story, and here Xiaomi offers more advanced solutions:
- 💦 Vibrational mop (models Mop 2 Pro) - simulates hand friction, better washes dried spots.
- 🔄 Automatic water change (at Ultra docking stations) – the robot washes and dries the cloth.
- 📱 Intensity adjustment through the application (3 humidity levels).
Redmond offers the basic washing function in most cases: a water tank + a cloth that simply wipes the floor. The efficiency is lower, but the price is appropriate. The exception is the Redmond RV-R650 model with electronic water control, but it costs like the average Xiaomi.
One important thing is that if you have flooring or laminate, the function of washing can be dangerous, because excess moisture causes the coating to bloat, and in this case, you should choose a model with dry cleaning or buy additional wipes for robots.
Make sure the robot supports washing function | Check the compatibility of the coating with wet cleaning | Use only special detergents |Tune areas where you do not need washing (carpets, carpet) |Test in a small area

5.Smart Functions and Ecosystem Integration
Xiaomi is the undisputed leader here, and their robot vacuum cleaners are integrated into the Mi Home ecosystem, allowing them to:
- 📱 Manage cleaning through voice assistants (Alice, Google Assistant).
- 🔄 Automation (e.g., start cleaning when no one is home").
- 📊 Receive reports on the area of the harvested territory and working hours.
Redmond offers its own app Ready for Sky, but its functionality is more modest:
- ⏱️ Cleaning timer.
- 📍 Manual control (like a drone).
- 🔕 No integration with other smart devices.
If you already have Xiaomi gadgets (lamps, sockets, sensors), their robot vacuum cleaner will be a logical addition. For those who do not use a smart home, the difference is not fundamental.
💡
In the Mi Home app, you can configure "excessive cleaning areas" - the robot will drive through them 2-3 times, which is useful for places where dust accumulates (for example, under the sofa).
Price and price-quality ratio
Budget models:
- 💰 Redmond RV-R350 (~15 000 ₽): basic cleaning, gyroscopic navigation, power of 2000 Pa.
- 💰 Xiaomi Mi Robot Vacuum-Mop Essential (~20 000 ₽): LDS-navigation, power 2500 Pa, floor washing.
Mid-segment:
- 💵 Redmond RV-R650 (~30 000 ₽): LiDAR, power of 3500 Pa, electronic water management.
- 💵 Xiaomi Robot Vacuum-Mop 2 Pro (~35 000 ₽): LDS, vibration mop, support for multi-room maps.
Premium:
- 💎 Xiaomi Robot Vacuum-Mop 2 Ultra (~60 000 ₽): automatic water change, self-purification, power of 4000 Pa.
Redmond wins in the budget segment (up to 25,000) ₽), But with the price increase, it makes no sense - it is better to pay extra and take Xiaomi with you. LDS and advanced functions.
💡
If your budget is up to 20,000 ₽ — Look towards Redmond. RV-R350 Or used Xiaomi models. Over 30,000. ₽ It is definitely better to pay for Xiaomi with laser navigation.
Maintenance and maintainability
Robot vacuum cleaners require regular care:
- 🧹 Cleaning the main brush (weekly).
- 🗑️ Replacement of filters (every 3-6 months).
- 🔋 Checking the contacts of the charging station (once a month).
Xiaomi is more "friendly" here:
- ✅ Easy to find spare parts (brushes, filters, batteries).
- ✅ Many video instructions for disassembly on YouTube.
- ✅ Official service centers in most major cities.
Redmond loses:
- ❌ It is more difficult to find original parts (often you have to order from China).
- ❌ Less information on repairs (even for popular models).
⚠️ Warning: If the robot stopped charging, first check the contacts on the base and the device itself — they often oxidize. Wipe them with alcohol. If the problem remains, the power supply may have failed. RV-R350).
