A Design That Goes Where Others Won't
One of the M210's biggest strengths is its small body design, with just an 11-inch diameter and 2.99-inch height. This allows it to slide under low-profile furniture like sofas, beds, and cabinets, ensuring a more thorough and complete clean even in tight spaces.
That slim profile isn't a compromise — it's a deliberate engineering choice. Most traditional vacuums, including pricier robot models, fail to reach the dust bunnies lurking under bed frames and behind cabinet toe-kicks. The M210 has no such limitation. At just under three inches tall, it works easily under or around beds, sofas, and other furniture for a thorough cleaning and high coverage.
The footprint itself — 11 inches across — is also notably compact compared to many competitors that run closer to 13–14 inches in diameter. In tighter hallways, around chair legs, and through narrow spaces between furniture, this translates to noticeably better real-world coverage. Size matters in robot vacuums, and smaller almost always wins.
The Brushless Suction System: A Smarter Approach to Pet Hair
Here's where the M210 genuinely separates itself from the pack. The unique brushless suction structure ensures that pet hair and dirt go into the dustbin easily — unlike roller brushes, suction does not entangle hair.
If you've ever spent ten minutes hunched over a robot vacuum with scissors trying to free a mat of tangled fur from a brush roll, you'll immediately appreciate why this matters. Traditional roller brushes are effective but notoriously high-maintenance when pets are in the picture. The M210 sidesteps the problem entirely with a brushless suction port powered by a digital motor.
Efficiently equipped with a diaphragm brushless motor, which generates about 2,000–2,200 Pa suction power, it features a large capacity of 500 ml dustbin and a tangle-free system; thus, it is a vacuum that is especially efficient in collecting pet hair and daily debris.
That 500ml dustbin is generously sized for this class of machine — large enough to handle a full cleaning session in a medium-sized apartment without requiring mid-run emptying. For households with one or two pets, expect to empty every two to three sessions.
Six Cleaning Modes for Every Scenario
Versatility is built into the M210's core. The vacuum cleaner robot offers six clean modes, including zigzag, random, spot, edge, schedule timed, and manual control.
Each mode serves a real purpose:
- Zigzag Mode is the workhorse — methodical, back-and-forth passes that systematically cover a room with minimal overlap. Use this for scheduled daily cleans.
- Random Mode is the spontaneous option, useful for quick top-up cleans when you need something done fast and don't need perfect coverage.
- Spot Mode concentrates cleaning in a small, defined area — perfect after cooking sessions or under a child's high chair.
- Edge Mode targets baseboards and room perimeters, the zones most vacuums neglect entirely.
- Scheduled Cleaning lets you set it and forget it entirely — clean floors even when you're away from home.
- Manual Control via the app gives you real-time directional control, useful for steering the M210 to specific trouble spots.
In edge cleaning, the robot cleans the corners and edges of the room. Combined with its slim profile, this makes the M210 particularly effective along skirting boards and in the awkward angles behind doors.
120 Minutes of Runtime: Enough for Real Homes
Battery anxiety is real in the robot vacuum world. Many budget models clock out after 60–80 minutes, leaving larger homes half-finished.
The M210 has a runtime of 120 minutes and can clean up to 1,300 square feet per charge in quiet mode. That's enough coverage for most single-floor apartments and medium-sized homes in a single pass.
The Lefant M210 uses lithium iron phosphate batteries to achieve up to 120 minutes of runtime. Lithium iron phosphate (LiFePO4) chemistry is notable for its longevity and stability — these cells degrade more slowly over time than standard lithium-ion, meaning the battery should retain its capacity meaningfully longer through hundreds of charge cycles.
When the job is done — or the battery runs low — the M210 can automatically return to the charging dock when the battery is low or cleaning is complete. No manual retrieval required. It simply heads home, docks, and recharges itself.
Smart Obstacle Avoidance and Stair Detection
The M210 doesn't navigate blindly. The M210 features upgraded 6D anti-collision sensors that detect obstacles and automatically adjust the cleaning path. This system uses infrared sensing to read the environment in real time, redirecting the robot around chair legs, pet bowls, cables, and other floor-level hazards.
Importantly, the M210 detects stairs to prevent falls and maneuvers around them to clean your entire home. Cliff detection is a non-negotiable safety feature for any multi-level home, and the M210 handles it reliably — the sensors read drop-offs in advance and steer clear.
It's worth noting that the M210 does not use LiDAR or camera-based mapping. Its navigation is sensor-driven rather than map-based, which means it won't create a floor plan or allow room-specific zoning. It doesn't have the ability to map rooms and set no-go zones like other more expensive robot vacuums. For most daily cleaning needs in a single-room or open-plan home, this isn't a limitation. For complex multi-room households requiring precise zone management, it's worth considering the trade-off.
Wi-Fi, App, and Alexa: Full Smart Home Integration
The M210 punches well above its price point when it comes to connectivity. Through the Lefant App, users can set schedules, adjust suction, monitor cleaning areas, and manually control the robot — all from their smartphone.
A quick note on setup: please make sure you are using the new app — Lefant — waiting for you to unlock more features that were not available in the old Lefant Life app. The newer app is significantly better, and downloading the correct version from the start avoids the most common connectivity confusion.
The vacuum also supports voice commands via Amazon Alexa and Google Assistant, enhancing its hands-free usability. Once connected, simple voice commands like "Alexa, ask Lefant to start cleaning" are all it takes to get your floors done without lifting a finger.
The M210 Pro enhances connectivity with Bluetooth + WiFi connection. Note: only compatible with 2.4GHz Wi-Fi. This is a standard limitation for smart home devices at this tier — just confirm your router broadcasts a 2.4GHz band (virtually all modern dual-band routers do).
Quiet Operation: A Genuine Low-Noise Machine
Noise is a frequently overlooked spec that shapes how and when you actually use a robot vacuum. An obnoxiously loud machine quickly becomes a machine you only run when you're out of the house.
The Lefant M210P is less noisy than most vacuums tested, measuring around 60dB at one meter — arguably in the good average. For reference, 60dB is roughly equivalent to normal conversation volume. You can comfortably have the M210 running in the background while watching television or working from home.
Customers describe the vacuum as extremely quiet and super efficient. Multiple real-world users have specifically noted that the low noise level was a deciding factor — especially in households with young children, light sleepers, or anxious pets.
Hard Floor Performance: Where the M210 Shines
The M210 is optimized primarily for hard flooring surfaces — hardwood, laminate, tile, and vinyl. It performed well on hardwood floors, picking up surface debris, and was particularly capable on surface-level debris including hair and dust.
For households with predominantly hard floors, this is the M210's home turf. The brushless suction pulls debris in cleanly without scattering it, and the dual side brushes sweep material inward from edges effectively.
The vacuum was efficient in sweeping dirt to the suction inlet due to its dual side brushes. On low-pile rugs and carpet transitions, the M210 manages reasonably well, though it doesn't replace a dedicated carpet vacuum for deep-pile cleaning. Think of it as your daily maintenance solution — the tool that keeps hard floors consistently clean between deeper cleaning sessions.
Easy Maintenance
The dustbin is found beneath the upper cover, which can be unfastened by simply lifting the flap and removing it through the designated tab. The dustbin opens to allow quick emptying. The air filter is also accessible and easy to clean or replace.
The M210 includes a HEPA filter — capable of capturing fine particles down to 0.3 microns — which is a meaningful feature for allergy-conscious households or homes with heavy pet dander. Filter cleaning is recommended every few sessions; the M210 includes a spare filter and a small cleaning brush in the box for exactly this purpose.
