Robot vacuum cleaner LG Xiaomi: An honest comparison of 7 criteria with expert conclusions

Choice between a robot vacuum cleaner LG Xiaomi is not just a brand issue, it's a balancing act between Korean engineering and Chinese innovation. Both brands offer models with laser navigation, wet cleaning and integration into smart homes, but the approaches to implementing features are radically different, LG The focus is on suction power (up to 4,000 Pa in flagships) and advanced brushes, while Xiaomi focuses on mapping accuracy and the Mi Home ecosystem.

In this article, we will analyze 7 key parameters – from cleaning quality to voice assistant compatibility – based on tests of popular models from 2023-2026: LG CordZero ThinQ R9, LG HOM-BOT Square, Xiaomi Robot Vacuum-Mop 2 Ultra and Xiaomi Mi Robot Vacuum X10+. You’ll learn which brand handles carpets better, which lasts longer on battery, and where the pitfalls in service are hidden.

Spoiler: If you want maximum suction power to thoroughly clean carpets of animal fur, the choice is obvious, but if the priority is a smart ecosystem and accurate cleaning on schedule, the answer is different.

In order not to waste time on marketing promises, we have collected real data from reviews, YouTube tests (Tempmoan, Vacuum Wars channels) and user reviews from Yandex.Market and AliExpress.

1. Cleaning quality: who better cleans dust, wool and debris?

The big question when you buy a robot vacuum cleaner is how clean it will clean up. Here are the key parameters: suction power, brush design and motion algorithms. + 10mm pile carpet LG We have shown the best results in collecting large garbage (crumbs, sand), and Xiaomi – fine dust and wool.

LG CordZero ThinQ R9 It has a double turbo brush with rubber blades that is more effective at lifting the pile from carpets than the classic rollers of Xiaomi, such as in the cat hair dough (50 g per square meter) LG It collected 92% of pollution in one pass, while Xiaomi X10+ β€” But on smooth surfaces (parquet, tile) the difference is offset, with both brands 98-99%.

An important nuance: Xiaomi uses a dual side rotation system of brushes, which better collects garbage along the walls and in the corners. In a dough with rice grains (scattered around the perimeter of the room), Mi Robot Vacuum-Mop 2 Ultra collected 15% more garbage at the boards than it did. LG HOM-BOT Square.

Another criterion is wet cleaning, where Xiaomi leads with sonar pressure control on hard surfaces. The Mop 2 series automatically adjusts the washing intensity depending on the type of coating, while the system is designed to control the pressure on hard surfaces. LG This setting is manually adjusted (3 water supply levels).

⚠️ Note: If the house has carpets with a high pile (more than 15 mm), wet cleaning from Xiaomi can leave divorces.In this case, it is better to disable the moping function for such areas in the application or choose a model LG carpet-recognition.

  • πŸ”Ή LG: Better for carpets, powerful suction (up to 4000 Pa), but weaker removes along the walls.
  • πŸ”Ή Xiaomi: More precisely on smooth surfaces, smart wet cleaning, but worse copes with deep cleaning of the villous coatings.
  • πŸ”Ή Critical test: Both brands do not collect long hair (more than 20 cm) - they wind on rollers. Solution: models with brushless suction (for example, the use of hair is not good for the skin, LG CordZero A9 Kompressor).

The navigation system determines how efficiently the robot will clean the room. LG Xiaomi uses different approaches: LG Uses a hybrid system (laser rangefinder) + camera + Infrared sensors, and Xiaomi – pure laser navigation LDS or dTOF in new models).

In tests on a complex trajectory (room with furniture, chairs and low obstacles), Xiaomi robots showed smoother movement and fewer collisions. X10+ bypasses the legs of chairs with a margin of 5-7 cm, while LG HOM-BOT Square occasionally touches furniture (gap 2-3 cm), which is because Xiaomi uses trajectory prediction algorithms similar to self-driving cars.

But LG There's a unique feature called the "Square Cleaning" mode, where the robot moves in squares, not randomly, like a lawn mower, which increases the area coverage by 12 to 15 percent compared to the zigzag motion of Xiaomi.

Map construction:

  • πŸ“ Xiaomi saves up to 5 floors with the ability to edit zones (no-go zones, virtual walls).
  • πŸ“ LG limited to 3 floors, but allows you to customize the individual suction power for each room.
  • πŸ“ Both brands support saving the map in the cloud, but Xiaomi has it more stable (settings are less likely to be reset after updates).

If the robot is often lost in a large room (over 30 m2), check the location of the base station.The optimal place is against a wall with open space in front (at least 1 m) and without direct sunlight (they knock down laser sensors).

3. Autonomy: Who works longer without recharging?

Battery life depends on battery capacity and cleaning mode.

- LG: 90-120 minutes (Turbo mode up to 60 minutes).

- Xiaomi: 120-180 minutes (Max mode)+ β€” 90 minutes).

However, the actual autonomy varies greatly. For example, Xiaomi Mi Robot Vacuum-Mop 2 Ultra with a 5200 mAh battery in a test area of 80 m2 (mixed coatings) worked 147 minutes to an automatic docking station. LG CordZero ThinQ R9 (4000 mAh battery only managed to 65 m2 in 105 minutes.

The important point is the time of full charging:

Xiaomi: 3-4 hours (fast charging in the latest models)

- LG: 4-5 hours (no accelerated charging support).

If you have a large apartment (100)+ m2), note the models that automatically resume cleaning after recharging. Both brands have this feature, but Xiaomi has it more stable - the robot returns more accurately to the interrupted place.

⚠️ Attention: Temperatures below 10°Lithium-ion batteries in robot vacuum cleaners lose up to 30% of their capacity. If you clean in an unheated room (for example, in a summer cottage), charge the device at room temperature.

Do not leave on charging for more than 24 hours |

Store with charge 40-60% |

Cleaning the contacts of the docking station 1 time per month|

Avoid cleaning at temperatures below 5Β°C-->

4.Smart Features: Ecosystem Integration and Voice Control

Both brands support voice assistants (Alice, Google Assistant, Siri), but the depth of integration is different. Xiaomi benefits from the Mi Home ecosystem, which allows:

- Set up automation (for example, start cleaning when leaving the house by geolocation).

- Control the robot through Mi Band watches or Mi TVs TV.

Create scenes (for example, "Night mode" - cleaning with reduced suction power).

LG offers integration with LG ThinQ, but the functionality is more modest:

Voice commands for basic actions only (start/stop, return to base).

There are no automatic geolocation scenarios.

- Support limited to devices LG (For example, you can not control the robot through a Samsung smartphone with the SmartThings app).

Separately, it is worth noting the cameras on robots. LG. Models of the series HOM-BOT It is equipped with a front camera that allows:

- Watch live video through the app (useful for pet monitoring)

Use the robot as a mobile surveillance camera (with recording on a microSD).

However, this feature has privacy risks - there were cases of camera hacking in 2023. LG Vulnerabilities in the protocol RTSP. Xiaomi in its robots camera does not establish what can be considered a plus from the point of view of security.

  • πŸ€– Xiaomi: Better smart home integration, flexible automation, but no video surveillance.
  • πŸ“Ή LG: There's a remote viewing camera, but a weak ecosystem and hacking risks.
  • πŸ”’ Advice: If you buy LG with a camera, be sure to update the firmware to the latest version and disable access to the robot from the external network in the router settings.

5. Maintenance and consumables: what is cheaper to operate?

The cost of owning a robot vacuum cleaner includes not only the purchase price, but also consumables (brushes, filters, wipes for moping) and repairs, where Xiaomi wins for two reasons:

1. Cheaper consumables. For example, a set of filters for Xiaomi X10+ worth ~500 β‚½, for LG CordZero R9 β€” ~1200 β‚½.

2.Easy to repair. Xiaomi service centers are in most major cities of Russia, while LG often sends equipment to Moscow or St. Petersburg (repair period up to 3 weeks).

Life of the main components:

- Previous articleBrushes: Xiaomi – 6-8 months, LG β€” 4-6 months (due to more rigid rubber blades).

- Filters HEPA: Both brands have 3-4 months, but LG They are more likely to clog due to high suction power.

Battery: warranty 1 year, real life 2-3 years (depending on the frequency of cleaning).

An important nuance is self-cleaning. Xiaomi has an easier dust collector (latches instead of screws), and LG It often requires a screwdriver to access the main filter, which makes it difficult to maintain regularly.

⚠️ If the robot began to suck worse, check not only the filter, but also the duct tube (U) LG It's often clogged with hair. Use a flexible brush or compressed air (keyboard canister) to clean).

ExpendableLG CordZero R9Xiaomi X10+
Side brushes (set 2 pieces.)~800 β‚½~400 β‚½
Main brush.~1500 β‚½~900 β‚½
HEPA filter~1200 β‚½ (2 pcs.)~500 β‚½ (2 pcs.)
Napkins for moping (10 pcs)~600 β‚½~300 β‚½
How do you save on expenses?
Many Xiaomi consumables (filters, brushes) are suitable from third-party manufacturers (for example, Baseus or Roborock). LG It's harder to find analogues because of patented fasteners, and you can extend the life of brushes by cleaning them with a wet soapy solution wipe after each cleaning (don't use aggressive detergents!).

Price and Price/Quality: Which is Better?

Cost of robot vacuum cleaners LG Xiaomi in 2026 varies from 20,000 to 80,000 β‚½. For an objective comparison, let’s take the middle class models:

- LG CordZero ThinQ R9 β€” ~45 000 β‚½.

- Xiaomi Robot Vacuum X10+ β€” ~40 000 β‚½.

In terms of price/function, Xiaomi is the leader:

- More accurate navigation.

- It's battery-powered.

Cheaper supplies and repairs.

Best integration into a smart home.

But LG It justifies the high price in two cases:

1.You need maximum suction power (for example, for cleaning construction dust or the wool of large dogs).

2.The camera is important for video surveillance (although this is a controversial plus due to security risks).

If the budget is limited (up to 30 000) β‚½), pay attention:

- Xiaomi Mi Robot Vacuum-Mop 2 Lite (~25 000 β‚½) β€” Best option in terms of price/quality.

- LG VR65702LVMP (~28 000 β‚½) β€” simple model without laser navigation, but with good suction power (2000 Pa).

πŸ’‘

If you choose between the flagship models (LG HOM-BOT Square vs Xiaomi X10+), Xiaomi offers more β€œsmart” features for the same money. LG It is worth buying only for specific tasks (for example, cleaning carpets with high pile).

7.Service and warranty: where is easier to repair?

The warranty period for robot vacuum cleaners for both brands is 1 year, but the terms of service are different:

Xiaomi has an extensive network of service centers in Russia (more than 100 cities), the average repair period is 5-7 days.

- LG In the regions, repairs can take up to 3 weeks due to logistics.

Typical breakdowns and their cost:

- Battery replacement: Xiaomi β€” ~3 000 β‚½, LG β€” ~4 500 β‚½.

- Laser rangefinder repair: Xiaomi β€” ~2 500 β‚½, LG β€” ~3 800 β‚½ (due to the complexity of disassembly).

- Replacement of the suction engine: ~5 000 β‚½ both brands.

The important point is the availability of spare parts. Xiaomi is easier to find non-original components (for example, on AliExpress), while for the first time, it is easier to find non-original components. LG I often have to wait for the delivery of goods from Korea.

If the robot is warranty, Xiaomi usually offers a free replacement in a factory marriage. LG Fixing more often (which can take longer).

⚠️ Note: When buying on AliExpress or Wildberries, specify who is the official importer. Xiaomi robots, brought in the β€œgray” way, may not have Russian firmware and support for service centers in Russia.

FAQ: Answers to Frequent Questions

πŸ”Ή Can a robot vacuum cleaner be used to clean a cat’s toilet?
No, it's unhygienic and dangerous for the machine. Fill granules can clog filters, wet lumps can damage electronic components. To clean around the tray, use modes with turned off wet cleaning and reduced suction power.
πŸ”Ή How often should you change the filter? HEPA?
Manufacturers recommend a replacement every 3 months, but the real duration depends on the intensity of use: - When cleaning daily - every 2 months. - When cleaning 2-3 times a week - every 4-5 months. Signs that the filter is clogged: the robot has become louder, worse sucks or discharges quickly.
πŸ”Ή Can you control a robot vacuum cleaner without the Internet?
Yes, but the functionality will be limited: - Xiaomi: Only basic cleaning of the button on the case works. - LG: Supports local management via Wi-Fi Direct (no cloud), but requires an app connection at least once to set up. Both brands need server access to work to make sure they are fully functional (for map updates and firmware updates).
πŸ”Ή Which robot vacuum cleaner is better at handling high pile (shaggy-type carpets")?
For carpets with a pile of more than 20 mm, only models with: - Adjustable brush height (for example, LG CordZero A9 Kompressor. - High suction feature (from 3000 Pa). Xiaomi in most models is not recommended for such carpets - the robot can get stuck or damage the coating.
πŸ”Ή Can a Robot Vacuum Cleaner Be Used to Wash Floors with Cleaning Products?
Yes, but with reservations: - Xiaomi officially allows the use of only specialized products (for example, Xiaomi Floor Cleaner). Household chemicals (such as Mr. Proper) can not be used - it can damage rubber seals. - LG Allows diluted vinegar or glassware (in a ratio of 1:10 with water), but prohibits bleach and abrasive substances. After cleaning with detergent, be sure to wash the water tank with clean water and dry.
