Key Differences Between Lefant M330 Pro and M320
Navigation Technology
M330 Pro: Features advanced LiDAR navigation with 190° PSD obstacle avoidance, creating precise maps and enabling room-by-room cleaning with virtual boundaries and no-go zones.
M320: Uses basic smart mapping with ultrasonic sensors, which provides adequate navigation but lacks the precision and advanced mapping features of LiDAR technology.
Winner: Lefant M330 Pro - The LiDAR navigation provides significantly more accurate mapping and efficient cleaning paths.
Suction Power
M330 Pro: Offers 4000Pa suction power, which is sufficient for most household cleaning tasks.
M320: Delivers 6000Pa suction power, providing stronger debris pickup, especially beneficial for homes with pets and high-traffic areas.
Winner: Lefant M320 - With 50% more suction power, the M320 has a clear advantage for deep cleaning performance.
Dustbin Capacity
M330 Pro: Features a 450ml visible dustbin that requires more frequent emptying.
M320: Comes with a larger 800ml visible dustbin, allowing for less frequent emptying and better suited for larger homes or homes with pets.
Winner: Lefant M320 - The significantly larger dustbin capacity is a practical advantage for everyday use.
Battery Life
M330 Pro: Provides up to 150 minutes of runtime on a single charge.
M320: Advertises up to 210 minutes of runtime, though real-world testing shows 90-150 minutes at maximum suction power.
Winner: Lefant M320 - Even with the discrepancy between advertised and actual runtime, the M320 still offers comparable or slightly better battery performance.
Pet Hair Handling
M330 Pro: Performs well with pet hair but uses a traditional brush roll design that may require more maintenance.
M320: Features a brushless suction design specifically optimized for pet hair, significantly reducing tangling and maintenance.
Winner: Lefant M320 - The brushless design gives it a clear advantage for homes with pets.
App Features and Customization
M330 Pro: Offers advanced app features including multi-floor mapping, room customization, no-go zones, and scheduled cleaning.
M320: Provides standard app functionality with basic scheduling and cleaning modes but lacks advanced mapping features.
Winner: Lefant M330 Pro - The more sophisticated app experience provides greater control and customization.

Lefant M330 Pro User Feedback
"The LiDAR navigation on the M330 Pro is a game-changer. It maps my entire home accurately and cleans in efficient patterns. The app is intuitive and I love being able to set no-go zones without physical barriers." - Tech-savvy homeowner
"Navigation is excellent and the obstacle avoidance actually works - it hasn't gotten stuck once in my furniture-heavy living room. The only downside is the smaller dustbin that needs frequent emptying with my two shedding dogs." - Pet owner with complex home layout
"The room-by-room cleaning feature is fantastic. I can send it to clean just the kitchen after dinner without disturbing the rest of the house. The mopping function is decent for maintenance cleaning between deeper mops." - Busy parent
Lefant M320 User Feedback
"The suction power on this vacuum is incredible! It handles pet hair without tangling thanks to the brushless design. The large dustbin means I only need to empty it once every few days instead of after every cleaning." - Multi-pet household owner
"Great suction power and battery life, but the navigation is hit or miss in my home with multiple rooms. It sometimes misses areas or gets confused about where it's already cleaned. App connectivity can be unreliable too." - Owner of large home
"The brushless design is perfect for my long-haired cats - zero tangling issues! Battery life is good but not as long as advertised when using maximum suction. Still, it's a great value for the cleaning power it delivers." - Cat owner with hardwood floors
Frequently Asked Questions
Which Lefant robot vacuum is better for pet hair?
The Lefant M320 is better for pet hair due to its brushless suction design and stronger 6000Pa suction power. This combination prevents hair tangling and provides more effective pickup of pet hair from various surfaces. The larger 800ml dustbin also means less frequent emptying when dealing with pet hair. The M330 Pro still performs well with pet hair but may require more maintenance with its traditional brush roll design.
Which model has better navigation capabilities?
The Lefant M330 Pro has significantly better navigation capabilities thanks to its LiDAR technology and 190° PSD obstacle avoidance system. It creates accurate maps of your home, enables room-by-room cleaning, and allows you to set virtual boundaries and no-go zones through the app. The M320 uses basic smart mapping with ultrasonic sensors, which provides adequate navigation but lacks the precision and advanced features of the M330 Pro's LiDAR system.
Can these robot vacuums work on multiple floor levels?
The Lefant M330 Pro supports multi-floor mapping, allowing it to remember and navigate different levels of your home. You can save multiple floor maps in the app and switch between them as needed. The M320 does not have multi-floor mapping capabilities and would need to recreate its navigation path each time it's moved to a different floor.
How effective are the mopping functions on these Lefant vacuums?
Both models offer basic mopping functionality that's suitable for light maintenance cleaning but not for deep cleaning or stubborn stains. The Lefant M330 Pro has a slight edge with its electronic water control system that provides more consistent water distribution. The M320 uses a simpler magnetic mop holder. Neither model should be considered a replacement for a dedicated mop for thorough cleaning.
Which Lefant model offers better value for money?
The answer depends on your specific needs. The Lefant M320 offers better value if you prioritize raw cleaning power, pet hair performance, and dustbin capacity. The M330 Pro provides better value if you have a complex home layout and need advanced navigation, room-by-room cleaning, and customization features. Consider which features matter most to you when determining value.
