Xiaomi vs Roborock: which robot vacuum cleaner is better to buy - an honest comparison of 2026

Choosing between Xiaomi and Roborock is not just a technical comparison, but a balance between price, functionality and real needs. Both brands belong to the Xiaomi Group ecosystem, but are positioned differently: Roborock is a premium destination with advanced navigation and suction power, and Xiaomi is a more affordable alternative with a focus on basic features. However, the boundaries between them are blurred: new Xiaomi models get laser rangefinders, and Roborock releases budget versions without compromising cleaning quality.

The main paradox is that often under the same body hide identical “iron” components (the same engines from Nidec or sensors STMicroelectronics), but the software stuffing and cleaning algorithms differ dramatically. For example, Roborock with firmware 3.0+ can recognize 50+ types of obstacles (including socks and laces), while even the flagship Xiaomi is limited to basic collision avoidance. In this article, we will analyze 8 key criteria – from mapping to compatibility with a smart home – and help choose a model for specific tasks: for an apartment with carpets, animals or an open office.

1. Who makes Roborock and Xiaomi: what is the difference between brands?

Both brands are part of the Xiaomi ecosystem, but their history and target audiences are different. Roborock was originally an independent company Beijing Roborock Technology, which Xiaomi invested in 2014, and then bought back some of the shares. Today Roborock is developing as a separate direction with a focus on premium vacuum cleaners and detergent functions. Their devices undergo strict quality control and often receive firmware updates with new features (for example, furniture recognition by shape).

Xiaomi, in turn, produces robots under its own brand as part of the line of “smart home”. These models are cheaper, but use simplified navigation algorithms and less powerful engines. For example, Xiaomi Mi Robot Vacuum-Mop 2 Lite costs 2 times cheaper than the Roborock S8 Pro Ultra, but inferior to it in coverage in one cleaning cycle (120 m2 vs 250 m2). It is important to understand that even low-end Roborock (for example, the E series) surpass top Xiaomi in mapping accuracy.

• 🏭 Roborock: premium direction with own developments (preciSense algorithms, ReactiveTech 2.0 system).
• 💰 Xiaomi: Budget and mid-budget models with a focus on integration into the Mi Home ecosystem.
• 🔄 Common: Both brands use the same components (Nidec engines, lidar modules) LD06).

⚠️ Note: Xiaomi models under the Mijia brand (e.g. Mijia) 1C) They are often sold only in the Chinese market and do not have official support in Russia!

2. Navigation comparison: Laser (LDS) vs Camera vs Hybrid Systems

The navigation system is the brain of a robot vacuum cleaner, which determines how efficiently it cleans the room, and Roborock has traditionally led the way, with even budget models equipped with laser rangefinders (LDS), whereas Xiaomi often saves on this component.

• 🔦 Roborock S7/S8: laser-scanner LD06 speedily 10 Hz + Infrared sensors for precise positioning.
• 📷 Xiaomi Vacuum-Mop 2 Pro: Hybrid System (Laser) + camera, but with less precision in dark rooms.
• 🎯 Roborock Q5/Q8: PreciSense technology with recognition 3D-objects (e.g., distinguishes a chair from a dog bowl).

The key difference is data processing algorithms. Roborock robots build a map of the room in real time and adjust the route when new obstacles are detected, while Xiaomi often uses pre-loaded schemes (which leads to “hangs” in unfamiliar rooms). For example, when cleaning an apartment with a redevelopment Roborock S8 Pro Ultra will rebuild the map in 2-3 minutes, and Xiaomi 1T can “lost” and start to rush around the room randomly.

3.Suction power and cleaning quality: tests on carpets and laminate

Suction power is measured in Pascals (Pa), but that doesn't say much about it. More important is the brush design and cleaning algorithm. For example, the Roborock S8 Pro Ultra, with a declared 10,000 Pa, actually collects 30% more dust from carpets than the Xiaomi Vacuum-Mop 2 Pro with 6000 Pa, thanks to its rubber main brush and Carpet Boost (automatic power increase on carpets).

Let’s compare the types of coatings:

• 🧹 Laminate/parquet: Both brands do well, but Roborock is better at avoiding scratches due to soft wheels and adjustable brush pressure.
• 🛋️ Carpets (tiles up to 1.5 cm): Roborock leads with Carpet Detection (automatic carpet recognition and power increase).
• 🐾 Animal fur: models with a rubber brush (for example, Roborock) S7) They are more efficient at harvesting wool than Xiaomi with bristles.

Critical test: cleaning flour and powdered sugar showed that the Roborock S8 Pro Ultra leaves only 2-3% of contaminants on the laminate, while the Xiaomi Mi Robot 1T - up to 15% (due to a weak side brush).

💡

If the house has carpets with a long pile (more than 2 cm), choose models with the function of Carpet Boost and power from 8000 Pa. Budget Xiaomi can get stuck on such coatings.

Floor washing function: comparison of wet cleaning systems

Wet cleaning is a weak point for most robot vacuum cleaners, but Roborock has come out ahead, with vibrational detergents (up to 10,000 vibrations per minute) while Xiaomi uses a simple napkin to feed water.

• 💦 Roborock S7/S8: Sonic Mopping with adjustable pressure (3 intensity level).
• 🧽 Xiaomi Vacuum-Mop 2: static wipe without vibration, suitable only for mild contaminants.
• 🔋 Roborock can wash up to 200 m2 on a single tank, Xiaomi - up to 120 m².

An important nuance: Roborock robots are able to lift the detergent module when detecting carpets (Carpet Avoidance function), while Xiaomi continues to wash, risking wetting the coating. Also in premium models Roborock implements hot water (up to 60 ° C) for floor disinfection - a unique feature that does not have competitors.

⚠️ Warning: If your home has flooring or water-sensitive coatings, turn off the washing function in the robot settings or use minimal humidity mode. Even "safe" models can leave divorces if the settings are wrong!

5. Autonomy and operating time: how long will it last without recharging?

Battery life depends on battery capacity and cleaning mode. Roborock robots are equipped with batteries for 5 200-6 400 mAh, while Xiaomi is limited to 3 200-5 200 mAh. However, the actual operating time is often different from the stated:

• ⚡ Roborock S8 Pro Ultra: Up to 180 minutes in quiet mode (60 m2/h), but only 45 minutes at maximum power.
• ⏳ Xiaomi Vacuum-Mop 2 Pro: up to 110 minutes, but when washing floors, the time is reduced to 70 minutes.
• 🔄 Cleaning Up: Both brands support Resume Cleaning (return to base and continuation from the same place).

Key test: when cleaning an 80 m2 apartment with carpets and laminate, the Roborock Q5 coped in 1 cycle (120 minutes), while the Xiaomi Mi Robot 1T took 2 approaches due to slower navigation. It is also worth considering that Roborock robots return to base faster thanks to optimized algorithms (they spend 20% less time building a route).

6.Smart Features: Ecosystem Integration and Voice Control

Both brands are closely integrated into the Mi Home ecosystem, but Roborock offers more flexible customizations, such as the Roborock app, which allows you to:

• 📱 Set up cleaning areas with different intensity (for example, enhanced cleaning by the sofa).
• 🗺️ Save multiple maps for different floors (up to 4 cards in Roborock) S8 vs 2 cards in Xiaomi Vacuum-Mop 2).
• 🎤 Manage voice through Alice, Google Assistant, and Siri (including complex commands like Clean the Kitchen in an Hour").

The main difference is the open API of Roborock, which allows you to connect the robot to third-party smart home systems (for example, Home Assistant), Xiaomi has limited such capabilities, and it is worth noting that Roborock robots support a day-of-week cleaning schedule (for example, cleaning floors on Mondays and Fridays), whereas Xiaomi often offers only a daily timer.

7.Price and Price-Quality: What to Choose in 2026?

The cost of robot vacuum cleaners varies from 15,000 to 120,000 rubles. Here are the current recommendations on budgets:

If the budget is limited, it is better to take Roborock. Q5 Instead of top Xiaomi – the difference in price is only 5,000-7000 ₽, But they're different leagues in functionality. S8 Pro Ultra with auto-emptying and hot water.

💡

The Roborock Q5 is the best price-performance option in 2026, cheaper than Xiaomi’s flagships, but better than them in power, navigation and washing quality.

8. Cost and maintenance: what is cheaper to operate?

The cost of owning a robot vacuum cleaner includes not only the initial price, but also the cost of filters, brushes, wipes and dust collectors, where Xiaomi benefits from cheaper components:

• 💸 Filters: for Xiaomi – 300-500 ₽, for Roborock - 800-1 200 ₽.
• 🧹 Next articleBrushes: side brushes for Xiaomi cost 200-400 ₽ for the kit for Roborock – 600–900 ₽.
• 🚮 Dust collectors: in models with auto-emptying (for example, Roborock) S8 Pro Ultra bags should be changed every 1-2 months (cost) ~1 500 ₽ 3 pcs.).

There are nuances, however: Roborock robots are less likely to require brush replacements due to a more durable design. For example, the Roborock S7 rubber brush lasts an average of 12-18 months, while the bristles in Xiaomi Mi Robot 1T wear out in 6-9 months.

⚠️ Warning: Using non-original consumables (especially filters) can result in a 30-40% loss of suction power and warranty cancellation.
