Roborock and Xiaomi: 7 fundamental differences that will affect your choice

When it comes to robot vacuum cleaners, Roborock and Xiaomi are often mentioned together. This is not surprising: both brands belong to the same ecosystem, but they offer fundamentally different approaches to cleaning. At first glance, it may seem that they are just two brands with the same devices under different logos. However, the difference between Roborock and Xiaomi affects not only design, but also software, navigation, smart home compatibility and even the philosophy of development.

If you’re looking at the Roborock S8 Pro Ultra vs. Xiaomi Mi Robot Vacuum-Mop 2 Pro, or just want to understand why some models cost 2 times more than others, this article will help you put it all together. We’ve analyzed 7 key differences that directly affect usability, cleaning quality and long-term satisfaction with your purchase. And at the end, you’ll find a comparison table and answers to the most common questions from users.

1.The Origins of Brands: Why is Roborock More Valuable than Xiaomi?

Roborock and Xiaomi are not competitors, but a subsidiary and parent brand, a story that began in 2014 when Roborock (then called Beijing Roborock Technology Co. Ltd.) partnered with Xiaomi to develop robot vacuum cleaners. The first model, the 2016 Mi Robot Vacuum, was released under the Xiaomi brand, but was actually created by Roborock engineers.

Over time, Roborock became a standalone brand (although Xiaomi remains its largest shareholder), focusing on the premium segment. S7 MaxV Ultra is worth it ~80 000 ₽, Xiaomi Mi Robot Vacuum-Mop 2 Lite ~20 000 ₽. Xiaomi offers “simplified” versions of Roborock technology, but under its own name and at a more affordable price.

• 🔹 Roborock is a premium brand with its own R&D centers and proprietary technologies (e.g. ReactiveAI 2.0 for obstacle recognition).
• 🔹 Xiaomi is a mass market where ready-made Roborock solutions are used, but with reduced functionality.
• 🔹 Both brands are compatible with the Mi Home ecosystem, but Roborock often gets updates sooner.

⚠️ Note: Some Xiaomi models (e.g. Mi Robot Vacuum-Mop P) are identical to Roborock E4, But they have different software and less accurate navigation!

2. Navigation and mapping: LDS vs visual sensors

One of the main differences is the navigation system. Roborock traditionally uses the same system. LDS-Laser Distance Sensor to map a room, while Xiaomi in the latest models switches to visual navigation (VSLAM) hybrid.

What does that mean in practice?

• 📍 Roborock (LDS):
• 📸 Xiaomi (VSLAM):

Exception: Xiaomi flagship models (such as Mi Robot Vacuum-Mop 2 Pro) are also equipped with the same equipment. LDS, But with stripped-down software, for example, they might not have a function. 3D-mapping or multi-storey card saving, which even mid-budget Roborock has.

3. Cleaning functions: suction force and wet cleaning

Here, Roborock is clearly in the lead – especially in the segment of hybrid robots (vacuum cleaner + mop). For example, the Roborock S8 Pro Ultra develops suction up to 10,000 Pa, while even the top Xiaomi Mi Robot Vacuum-Mop 2 Pro is limited to 4000 Pa. The difference is noticeable on long-pile carpets or when cleaning construction dust.

Another key difference is the wet cleaning system:

• 💦 Roborock:
• 💧 Xiaomi:

Critical nuance: In Xiaomi models below the Mi Robot Vacuum-Mop 2 Pro, the mop is fixed – this means that when cleaning carpets, the fabric will be constantly wet, which can lead to mold or damage to the coating.

💡

If you have a lot of carpets at home, choose Roborock models with Carpet Detection function – the robot automatically raises the mop on the carpets.

4. Software and ecosystem

Both brands work through the Mi Home app, but the functionality is very different.Robock offers advanced customizations:

• 📱 Cleaning areas with priority (e.g. kitchen first, then corridor).
• 📱 Virtual walls and “no-go zones” with exact map binding.
• 📱 Room schedule (for example, vacuum the bedroom only during the day).
• 📱 Integration with Google Assistant, Alexa and Apple HomeKit (Xiaomi HomeKit supports only flagships).

Xiaomi has often stripped down even basic features, such as Mi Robot Vacuum-Mop 2 Lite, which does not include:

• ❌ Save a few floors.
• ❌ Adjust the intensity of suction by zone.
• ❌ Use voice commands to clean a particular room.

Another important point is firmware updates. Roborock releases patches every 1-2 months, adding new features (such as shoe recognition or children's toys). Xiaomi updates the software less often, and some budget models generally remain on the old version.

5. Batteries and operating times

Battery life depends on the model, but in general, Roborock is equipped with more capacious batteries:

• 🔋 Roborock S7 MaxV: 5,200 mAh, up to 3 hours of cleaning.
• 🔋 Xiaomi Mi Robot Vacuum-Mop 2 Pro: 3,200 mAh, up to 1.5 hours.
• 🔋 Xiaomi budget (for example, 1C): 2,600 mAh, up to 1 hour.

However, there is a caveat: Roborock often uses active cooling of the battery, which extends its life to 5-6 years (versus 2-3 years for Xiaomi).In addition, premium models Roborock implemented a function Quick Boost — the robot can interrupt cleaning, recharge 20% in 10 minutes and continue working.

⚠️ Warning: If you buy a robot vacuum cleaner "for growth" for a large apartment (100)+ m2), note Roborock models with automatic refueling support (e.g, S8 They can go back to the dock to recharge and resume cleaning from the same place.

6.Compatible with smart home and voice assistants

Both brands are integrating into the Mi Home ecosystem, but Roborock offers a deeper customization:

• 🏠 Mi Home Automations:
• 🗣️ Voice assistants:

In addition, Roborock allows you to configure geofences through Mi Home: for example, the robot can start cleaning when you go to work (according to the geolocation of the smartphone), or suspend it if a person enters the room (via motion sensors Xiaomi Motion Sensor).

Make sure the robot supports your voice assistant (check the specs)

If you use Apple HomeKit, choose only the flagship Roborock models.

7.Price and target audience: what to choose in 2026?

💡

If the budget allows, it is better to buy a mid-range Roborock once (for example, Q Revo) than to change Xiaomi’s budget models every 2 years.
