Two Slim Vacuums, One Big Decision
The Lefant M210 and M310 sit just $30–$40 apart on Amazon, yet the gap in capability is surprisingly wide. The M210 is Lefant’s entry-level staple—compact, simple, and priced to move at under $100 during sales. The M310 adds more suction, a larger dustbin, and optional mopping, positioning itself as the smarter pick for anyone with pets or mixed flooring. Both lack LiDAR mapping, both rely on app control, and both are whisper-quiet. So where does the extra money actually go? Let’s break it down.
Lefant M210: The Ultra-Compact Starter
Best for: Studio apartments, hard floors, and buyers who want the cheapest reliable robot vacuum on the market.
The M210 has sold over 15,000 units on Amazon with a 4.1-star average, and the appeal is obvious: it is tiny, affordable, and gets the job done on smooth surfaces. At 2.8 inches tall and 11 inches in diameter, it is one of the slimmest robot vacuums available—sliding under beds and sofas that bulkier units simply cannot reach. The body weighs just 3 kg, making it easy to carry between rooms or floors.
The 2200Pa suction is modest but sufficient for hardwood, tile, and low-pile carpet. Crumbs, dust, and surface-level pet hair get picked up without drama. The real standout is the brushless suction inlet—there is no roller brush to trap hair. For pet owners who are tired of performing weekly “hair-ectomies” with scissors, this design is a genuine relief. Dual side brushes sweep debris toward the central inlet, and the 500ml dustbin holds a respectable amount of dirt for such a small machine.
Navigation is basic: Freemove 3.0 uses infrared sensors and a gyroscope to guide the unit in semi-random patterns. It does not map your home, and it will bump into furniture more often than premium models. But given enough time, it covers the room. Six cleaning modes are accessible through the Lefant app or the included remote: auto, zigzag, spot, edge, schedule, and manual. The app also supports Alexa and Google Assistant voice commands.
Battery life is 120 minutes in quiet mode, enough for apartments under 1,000 square feet. When the battery runs low, the unit returns to its charging dock automatically.
Key Specs:
- Suction: 2200Pa
- Runtime: Up to 120 minutes
- Dustbin: 500ml
- Height: 2.8 inches (71mm)
- Weight: 3 kg
- Navigation: Gyroscope + infrared (no mapping)
- Control: Lefant app, Alexa, Google Assistant, remote
- Price: ~$90–$130 (frequently discounted to under $100)
Lefant M310: The Step-Up with Real Teeth
Best for: Pet owners, mixed flooring, and anyone who wants more suction and less frequent dustbin emptying.
The M310 is not a revolution—it is a refinement. Lefant took the M210’s core formula, added meaningful upgrades, and kept the price under $150. The result is a robot vacuum that punches above its weight in the budget category.
The headline upgrade is 4500Pa suction—more than double the M210’s power. That extra force makes a real difference on low-pile carpets, where the M310 pulls embedded hair and grit that the M210 leaves behind. On hardwood, both units perform similarly, but the M310 cleans edges and high-traffic areas faster, often finishing in a single pass where the M210 needs two.
The 550ml dustbin is slightly larger, but the more significant improvement is the HEPA filter and allergy filter—features the M210 lacks. For households with allergy sufferers, this is not a minor detail. The M310 also introduces carpet detection, automatically boosting suction when it transitions from hard floors to rugs.
Navigation gets a meaningful upgrade too. The M310 uses PreciSense PSD technology with nine front-facing triangular sensors, providing a 190° field of view for obstacle detection. It slows before contact and navigates cluttered spaces with noticeably more confidence than the M210. It is still not LiDAR-level precision, but the incidence of the unit trapping itself under chair legs or ramming into pet bowls drops significantly.
The M310 also adds 2-in-1 sweep and vacuum capability with an optional magnetic mop holder. The honeycomb-textured mop pad attaches in seconds and handles light daily grime on tile and laminate. It is not a replacement for a proper mop, but for maintenance cleaning between deep scrubs, it is genuinely useful. A word of caution: do not use the mop on carpet.
Battery life extends to 140–160 minutes depending on the power mode, covering roughly 3,000 square feet in quiet mode. The unit self-charges and resumes cleaning, though the resume function is less reliable than premium competitors.
Amazon buyers rate the M310 at 4.2 out of 5 stars, with consistent praise for its pet hair pickup and quiet operation. One reviewer noted, “It does a great job picking up dust, hair, and crumbs, especially on hard floors. It’s easy to set up and runs smoothly.” Common complaints focus on the app only supporting 2.4GHz Wi-Fi and the mop being a light-duty add-on rather than a true cleaning tool.
Key Specs:
- Suction: 4500Pa
- Runtime: Up to 160 minutes
- Dustbin: 550ml
- Height: 2.99 inches (76mm)
- Weight: 3.17 kg
- Navigation: PreciSense PSD with 9 sensors (no mapping)
- Mopping: Optional magnetic holder (not included in all bundles)
- Control: Lefant app, Alexa, Google Assistant
- Price: ~$120–$160

Suction and Cleaning Performance
The M310’s 4500Pa suction is the deciding factor for anyone with carpets or multiple pets. On hardwood, both units are competent, but the M310’s stronger motor and wider intake clean faster and more thoroughly. The M210’s 2200Pa is fine for light daily maintenance, but it struggles with embedded debris and medium-pile rugs.
Verdict: M310 wins decisively.
Navigation and Smart Features
Here is where it gets interesting. The M210 actually has basic route mapping, while the M310 does not. The M210’s gyroscope creates a rough internal map, which can be viewed in the app. The M310 abandons mapping in favor of PreciSense obstacle avoidance—a trade-off that prioritizes not bumping into things over knowing exactly where it has been.
For cluttered homes with kids, pets, and furniture everywhere, the M310’s superior obstacle detection is the better choice. For open-concept apartments with minimal obstacles, the M210’s mapping is a nice bonus.
Verdict: Depends on your home layout. M310 for cluttered spaces, M210 for open plans.
Health and Filtration
The M310’s HEPA and allergy filters are a clear win. The M210 has no specialized filtration, meaning fine dust and allergens can recirculate. If anyone in your household has allergies or asthma, the M310 is the only responsible choice between these two.
Verdict: M310 wins by default.
Mopping and Versatility
The M210 does not mop. The M310 offers an optional magnetic mop holder that turns it into a light-duty sweeper-mopper. It will not replace a Swiffer or steam mop, but for daily maintenance on tile and laminate, it is genuinely useful. The fact that you can use your own wet/dry disposable face towels with the holder—instead of buying proprietary pads—is a nice money-saving touch.
Verdict: M310 wins by default.
Maintenance and Daily Living
Both units are low-maintenance, but the M310 edges ahead. Its larger dustbin means less frequent emptying, and the HEPA filter is washable. The M210’s brushless design means zero hair tangles, while the M310’s side brushes are easy to pop off and clean. Both operate at roughly 60 decibels—quiet enough to run during a phone call or a Netflix binge.
Verdict: M310 wins for larger homes; M210 is fine for smaller spaces.
Price and Value
At roughly $90–$130, the M210 is one of the best pure values in robot vacuums. During Amazon sales, it drops below $100, making it an impulse-buy no-brainer for small apartments. The M310, at $120–$160, asks for a meaningful step up. The question is whether the extra $30–$40 delivers enough utility. For homes with carpets, pets, allergies, or a desire for mopping, the answer is a clear yes. For a studio with hard floors and minimal debris, the M210 gives you 75% of the performance for 70% of the cost.
Verdict: M210 wins on pure price; M310 wins on features-per-dollar.

- Your floors are 100% hardwood, tile, or laminate
- You want the absolute cheapest reliable robot vacuum
- Pet hair is light, and you hate untangling brushes
- You do not need mopping, HEPA filtration, or advanced navigation
Buy the M310 If…
- You have a mix of hard floors and low-pile carpets
- You own pets and need stronger suction for embedded hair
- Someone in your home has allergies (HEPA filter is essential)
- You want light mopping capability without buying a second device
- You are willing to spend ~$140 for a more capable all-rounder
Final Verdict
For most households, the Lefant M310 is the smarter investment. The doubled suction, HEPA filtration, carpet detection, and optional mopping justify the extra $30–$40 for anyone with carpets, pets, or allergy concerns. It delivers roughly 85% of what a $250 Eufy or Roborock offers at nearly half the price. The M310 earns an 8.0/10.
The Lefant M210 remains a legitimate budget champion, but its limitations are real. No HEPA filter, no carpet detection, and modest suction make it a hard sell at full price when the M310 is just $30 more. That said, when the M210 drops below $100 during sales, it is genuinely difficult to beat for small, hard-floor apartments. It earns a 7.2/10.
Bottom line: The M310 is the better vacuum. The M210 is the better deal— but only when it is on sale.
