Design Innovations for Modern Homes
The slim 2.99-inch profile of the Lefant M310 allows it to glide under couches and beds with ease, tackling dust in neglected corners. Its champagne grey finish gives it an understated, modern look suitable for most interiors.
What sets this vacuum apart is its PreciSense Obstacle Avoidance system, which uses nine positional sensors to maneuver around objects with a 190° field of view. This results in fewer bumps and less chance of the robot getting stuck.
Lefant’s Freemove Tech 3.0 ensures the vacuum can free itself if it encounters trouble, increasing the odds of completing routines without manual intervention.
Performance: Suction, Coverage, and Carpet Capability
The 4500Pa suction power is outstanding in its price class, enabling the M310 to lift dust, pet hair, and crumbs from hard floors and low pile carpets. Twin side brushes extend coverage into corners and along edges.
Many users praise its ability to handle pet hair on hardwood floors, making it ideal for pet-owning households. The anti-tangle design lessens hair-wrapping woes.
On carpets, feedback is mixed regarding suction effectiveness. While the M310 manages low-pile carpet debris, thicker and high-pile carpets may not be its strong point.
Battery Life, Charging, and Dustbin Management
A standout spec is the 160-minute runtime per charge (in quiet mode), which is suitable for apartments and medium-sized homes. The M310 automatically returns to its dock to recharge when needed.
With a 550ml dustbin, users can clean larger spaces with fewer interruptions. The included HEPA filter, along with a metal pre-filter, traps fine dust and pet dander—a plus for allergy sufferers.
However, several owners report battery longevity concerns, noting that the battery may degrade after a few months of use. This is worth considering if you plan frequent or intensive cleaning sessions.
Smart Controls and Automation Features
App-based scheduling and mode selection are major perks for the Lefant M310’s flexible smart control. The unit is compatible with Alexa and Google Assistant, enabling hands-free cleaning with simple voice commands.
Switching between four cleaning modes—auto, edge, spot, and manual—is straightforward in the Lefant app. The M310 also supports routine scheduling for hassle-free maintenance.
Note that the M310 only supports 2.4GHz Wi-Fi networks. Setup is typically quick, but those with dual-band routers may need to adjust their settings.
User Experience: Pros, Cons, and Notable Feedback
Based on over 1,370 reviews, the Lefant M310 enjoys a 4.1-star average rating among buyers. It stands out for quiet operation, strong cleaning ability, and value for money.
About 85% of customers comment positively on cleaning performance and ease of use. Many mention hassle-free routines on hard floors and under-furniture areas. Programming the robot via the app earns frequent praise.
Mixed or negative feedback (~15% of users) most often cites short battery lifespan, and challenges with thicker carpets. Suction strength is well-rated for hard floors but “just adequate” for rugs.
User Feedback Snapshot: What Real Owners Are Saying
| Aspect | Sentiment | Snippet / Example Review |

| Value for money | Positive | “Best robot vacuum for the price.” |

How the Lefant M310 Compares to Alternative Robot Vacuums
In the budget category, the Lefant M310 faces competition from the Eufy RoboVac 11S and the iRobot Roomba 694, two proven names with similar specs.
| Model | Suction Power | Run Time | Dustbin | Smart Features | Low Profile | Carpet Performance |
|---|---|---|---|---|---|---|
| Lefant M310 | 4500Pa | 160 min | 550ml | App, Alexa, Google | 2.99 in | Low-pile only |
| Eufy RoboVac 11S | 1300Pa | 100 min | 600ml | Remote (no app) | 2.85 in | Fair |
| iRobot Roomba 694 | 600Pa (est.) | 90 min | 300ml | App, Alexa, Google | 3.54 in | Good |
The Lefant M310 offers notably higher suction and longer runtime compared to both rivals. Its ultra-slim body is on par with the Eufy, while app scheduling and voice controls outpace the 11S. The Roomba 694 leads on carpet cleaning, but the Lefant excels for hard floors and pet hair at a lower average sale price.
