After testing dozens of robot vacuums across all price ranges, I was genuinely curious about what the Lefant M210B could deliver at its remarkably low price point of just $89. Could a budget-friendly robot vacuum actually provide meaningful cleaning performance?
I've spent the last three weeks putting the Lefant M210B through its paces in my 1,200 sq ft apartment with hardwood floors, area rugs, and a shedding cat. The short answer: I'm impressed by what this little vacuum can do for the price, though it comes with some expected limitations.
The Lefant M210B is surprisingly quiet during operation, noticeably quieter than many premium models I've tested. Its slim 2.8-inch profile allows it to navigate under most furniture with ease, and the 2000Pa suction—while not industry-leading—handles everyday dust, hair, and small debris effectively on hard floors.
The mopping function is basic but functional for light maintenance cleaning. Don't expect it to handle sticky spills or deep cleaning, but it does provide a nice refresh to hard floors between manual mopping sessions.
For budget-conscious shoppers or those new to robot vacuums, the Lefant M210B represents excellent value and a great entry point into automated cleaning. Just set your expectations accordingly—this is an effective helper for daily maintenance, not a replacement for occasional deep cleaning.
Key Features of the Lefant M210B
2000Pa Suction Power
While not as powerful as premium models, the 2000Pa suction is sufficient for daily cleaning of dust, hair, and small debris on hard floors and low-pile carpets.
2-in-1 Vacuum & Mop
Includes a 110ml water tank and mopping pad attachment for light wet cleaning of hard floors after vacuuming.
500ml Dustbin
The larger-than-average dustbin capacity is sufficient for daily cleaning of small to medium-sized homes without frequent emptying.
Ultra-Slim Design
At just 2.8 inches tall, the Lefant M210B easily slides under furniture to clean hard-to-reach areas.
App Control & 6 Cleaning Modes
The Lefant app allows for scheduling, remote control, and selection between 6 different cleaning modes. While the interface is basic compared to premium models, it provides stable connectivity and all essential functions. Compatible with both iOS and Android devices.
Anti-Tangle Technology
Brushless suction port design helps prevent hair tangling, reducing maintenance compared to traditional brush roll designs.
100-Minute Runtime
The 1800mAh battery provides up to 100 minutes of cleaning time on a single charge, sufficient for most small to medium-sized homes.
The Lefant M210B delivers surprisingly good cleaning performance for its price point. On hard floors, it picks up dust, hair, and small debris effectively. The 2000Pa suction power is adequate for daily maintenance cleaning, though it may struggle with larger debris or embedded dirt.
On carpets, performance is more limited. The M210B can handle low-pile area rugs but lacks the power needed for medium to high-pile carpets. If your home has mostly hard floors with a few area rugs, you'll be satisfied with the cleaning results.
Navigation System
Unlike premium robot vacuums with LiDAR or camera-based mapping, the Lefant M210B uses a more basic random navigation pattern with infrared sensors to detect and avoid obstacles. It bounces around somewhat randomly, which means cleaning takes longer and may miss some spots. However, if you run it regularly, it will eventually cover your entire floor space.
The infrared sensors do a decent job of preventing collisions with furniture and walls, though it occasionally bumps into objects with gentle force. The cliff sensors reliably prevent falls down stairs.
Mopping Functionality
The mopping function is basic but functional. The 110ml water tank slowly releases water to dampen the microfiber pad, which then wipes the floor as the robot moves. It's effective for light maintenance mopping but won't replace a traditional mop for deeper cleaning or sticky spills.
One limitation is that the M210B cannot detect carpets while mopping, so you'll need to manually block off carpeted areas or remove area rugs before using the mopping function.

Budget-conscious shoppers looking for their first robot vacuum without a significant investment
Homes with primarily hard floors and low-pile area rugs
Small to medium-sized apartments where advanced navigation is less critical
Pet owners seeking a maintenance solution for daily hair cleanup

Setup and Ease of Use
Initial Setup
Setting up the Lefant M210B is straightforward and takes about 10 minutes from unboxing to first cleaning run:
Remove the robot and charging dock from the packaging
Install the side brushes (snap-on installation)
Place the charging dock against a wall with 3 feet of clearance on each side
Turn on the robot using the power switch on the side
Place the robot on the charging dock for initial charging (about 5-6 hours for full charge)
Download the Lefant app from the App Store or Google Play
Create an account and follow the in-app instructions to connect the robot to your Wi-Fi network
App Experience
The Lefant app is basic but functional, offering essential controls and features:
Remote control: Manually direct the robot's movement
Cleaning modes: Auto, Spot, Edge, and Zigzag patterns
Scheduling: Set up daily or weekly cleaning schedules
Suction control: Choose between Standard and Max power modes
Find My Robot: Triggers a sound to locate the robot if it gets stuck
The app interface is intuitive enough for most users, though it lacks the polish and advanced features of premium robot vacuum apps. Occasional connectivity issues may require reconnecting the robot to Wi-Fi.
Voice Assistant Integration
The M210B works with both Amazon Alexa and Google Assistant, allowing for basic voice commands like "Start cleaning" or "Send the robot home." Setup requires linking your Lefant account through the Alexa or Google Home app.
Real-Life Performance
Hard Floors
Excellent performance on hardwood, tile, and laminate. Picks up dust, hair, and small debris effectively with minimal noise. Struggles somewhat with larger debris like cereal pieces.
Carpets & Rugs
Good on low-pile carpets but performance drops significantly on medium-pile carpets. Not recommended for homes with primarily carpeted floors.
Mopping Function
The mopping function provides light surface cleaning but lacks scrubbing action. Effectively removes dust and light surface dirt but struggles with dried spills or sticky residue.
In real-world testing, the M210B consistently impressed with its quiet operation and ability to clean under low-profile furniture. The 2000Pa suction power is sufficient for everyday cleaning on hard floors, though it may require multiple passes for heavily soiled areas. Pet hair is handled well thanks to the brushless suction design that minimizes tangling.
The random navigation pattern eventually covers about 85% of accessible floor space, though it takes longer than mapping-enabled robots. Some corners and edges may be missed, and you might need to run it again to clean exposed areas. Battery life is good, averaging 95 minutes on standard suction mode and 70 minutes on max suction.

Who Should Skip It
The Lefant M210B isn't the right choice for everyone. Consider alternatives if you:
Have primarily medium to high-pile carpets: The 2000Pa suction isn't powerful enough for deep carpet cleaning
Need advanced navigation: If you want room mapping and targeted cleaning, look at more premium options
Have a large home: The random navigation and limited battery may struggle with larger spaces
Need deep mopping: The basic mopping function won't replace traditional mopping for thorough cleaning
Want a completely hands-off experience: You'll need to empty the small dustbin frequently and prepare spaces for mopping
Frequently Asked Questions About the Lefant M210B
Does the Lefant M210B work well for pet hair?
Yes, the Lefant M210B performs surprisingly well with pet hair, especially on hard floors. Its brushless suction design helps prevent hair tangling, which is a common issue with traditional brush roll designs. While it won't match the pet hair performance of premium models like the Roomba j7+, it's quite effective for daily maintenance in homes with pets, particularly at its budget price point.
Can the Lefant M210B create maps of my home?
No, the Lefant M210B does not have mapping capabilities. It uses a more basic random navigation pattern with infrared sensors to detect and avoid obstacles. It doesn't create or save maps of your home, nor can it target specific rooms for cleaning. If mapping is important to you, you'll need to consider mid-range or premium robot vacuums that include LiDAR or camera-based mapping systems.
How does the mopping function work?
The mopping function on the Lefant M210B is fairly basic. It includes a 110ml water tank that you fill manually and attach to the bottom of the robot along with a microfiber mopping pad. As the robot moves, water slowly seeps onto the pad to dampen it. The robot then drags this damp pad across your floors to wipe up dust and light dirt. There's no scrubbing action or variable water flow. The robot cannot detect carpets while mopping, so you'll need to block off carpeted areas or remove area rugs before using this feature.
How loud is the Lefant M210B during operation?
The Lefant M210B is relatively quiet compared to many robot vacuums. In standard suction mode, it operates at approximately 55-60 decibels, which is about the volume of a normal conversation. In max suction mode, the noise level increases to around 62-65 decibels, which is still quieter than many traditional vacuum cleaners. Many users specifically mention the quiet operation as a positive feature in their reviews.
How long does the battery last and how long does it take to charge?
The Lefant M210B features an 1800mAh battery that provides approximately 100 minutes of runtime in standard suction mode and about 70 minutes in max suction mode. A full charge takes approximately 5-6 hours. The robot will automatically return to its charging dock when the battery is low, though it may have trouble finding the dock in complex room layouts due to its basic navigation system.
The Lefant M210B represents exceptional value in the budget robot vacuum market. At just $89, it delivers surprisingly good cleaning performance on hard floors and low-pile carpets, with the added bonus of a basic mopping function.
While it lacks the advanced features and premium performance of higher-end models, it excels at what matters most for budget-conscious shoppers: reliable daily cleaning at an affordable price. The slim design, quiet operation, and anti-tangle technology make it particularly appealing for apartments, small homes, and pet owners.
If you're looking for your first robot vacuum or a secondary cleaner for daily maintenance, the Lefant M210B offers an excellent entry point into automated cleaning without a significant investment. Just set your expectations appropriately—this is a budget helper for regular maintenance, not a premium all-in-one cleaning solution.
