Don’t let the small size fool you — Lefant’s little robots are serious about keeping your floors spotless.

Based in China, Lefant focuses on compact, slim-profile bots that squeeze under furniture and keep things simple. Their lineup mostly skips flashy AI features in favor of straightforward functionality: strong suction, tangle-free brushes, and long runtimes.

If you want a basic robovac that gets the job done without the bells and whistles, Lefant might just be your next quiet little workhorse.

Stick around — you’ll be surprised what these tiny bots can pull off.

Affordability

4.6 /5

Lefant offers a range of models to suit various budgets:

Entry-Level: Like the M210, with 2200Pa suction and a 120-minute runtime, is available for as low as $89 during promotions.

Mid-Range: The F1 model, featuring 4000Pa suction and a 200-minute runtime, was previously listed at $326.40 on Lefant's official store.

Flagship: The M2 Pro, equipped with a Mini Smart Dock for self-emptying and a 4,000mAh battery, is listed at $699 on Lefant's official store.

These prices reflect Lefant's commitment to providing value-packed options across different tiers, making robotic cleaning accessible to a broad audience.

Build Quality & Durability

3.6 /5

Generally speaking, most Lefant products are designed with practicality in mind. Their compact, low-profile designs (as slim as 2.8 inches) allow them to navigate under furniture with ease. The minimalist approach means fewer moving parts, reducing potential points of failure. However, some users have noted that certain models, like the M210 Pro, may have lighter chassis and less robust wheel assemblies, which could affect performance over time.

Smart Features, Innovation & Technologies

2.8 /5

You can control most Lefant models through their mobile app, with features like spot cleaning, scheduling, and suction level adjustment. They also support voice control through Alexa and Google Assistant. That said, the app experience can be hit-or-miss — some users report clunky UI and occasional syncing issues. There’s no smart mapping or camera view, but you do get access to cleaning history and basic controls.

They also include quiet mode for low-noise cleaning, zigzag cleaning patterns for better floor coverage, and auto-boost on carpet, which increases suction when the vacuum detects a rug or carpeted area — a helpful touch for mixed-floor homes.

Motor & Cleaning Power

3.8 /5

Lefant’s newer models, like the F1, now push up to 5000Pa of suction — impressive at this price point. The brand uses a brushless, direct suction design, which means no roller brush — a deliberate choice to avoid hair tangles and simplify maintenance, especially in pet-heavy homes.

Older and entry-level models like the M210 and T800 typically offer 1800Pa to 2200Pa of suction, using standard brushless motors that are quieter but less aggressive — still effective for dust and crumbs, but not ideal for deep carpet debris. While you won’t find intelligent suction adjustment based on floor type, these bots still perform well on hard floors and low-pile carpets.

Navigation & Mapping Technology

2.6 /5

Lefant skips LiDAR and cameras entirely, relying instead on its FreeMove™ tech — a network of infrared sensors that detect obstacles and prevent falls. It’s a bump-and-go system, meaning navigation isn’t very “smart” by modern standards, but it does work reliably in smaller, clutter-free spaces. Some models include gyroscope-based mapping for basic area coverage tracking, though you won’t get live maps or room-level control.

Docking Station System

2.8 /5

Well, Lefant keeps things simple here. Most models return to a standard charging dock and don’t offer any dustbin auto-emptying or mop-cleaning features. You’ll need to empty the dustbin yourself after every run.

However, their flagship M2 Pro model introduces Lefant's Mini Smart Dock, a significant upgrade from the standard charging base. This compact station offers self-emptying dustbin and integrated water tank, coming in an ultra compact design.

Generally they are suitable for users seeking simplicity and space-saving solutions.

Obstacle Avoidance & Object Recognition

3.0 /5

Lefant's approach to obstacle avoidance varies across its product range, utilizing different technologies to enhance navigation and prevent collisions.

FreeMove 3.0™: This system can be found in most of their models and employs a network of infrared sensors to detect obstacles and prevent falls. It's effective for basic navigation, helping the robot avoid walls, furniture, and stairs.

PreciSense™ Obstacle Avoidance: Found in models like the M310, this technology uses nine position-sensitive detectors powered by PSD (Position Sensitive Detector) technology. It offers a 190° field of view, allowing the robot to detect objects as close as 1.6 inches away and identify items 2 inches or taller, regardless of shape, color, or transparency.

Laser Detection: Advanced models, such as the N3, incorporate laser detection for more precise obstacle avoidance and room mapping. This technology enables the robot to navigate complex environments more effectively. 

While these systems enhance the robot's ability to navigate and avoid obstacles, it's important to note that performance can vary depending on the environment, and smaller items like cables or pet toys might still pose challenges for the robot's sensors.

Battery Life & Coverage Area

3.9 /5

Battery life is one of Lefant’s stronger suits. Models like the F1 come with a 4000mAh battery, giving up to 200 minutes of runtime in quiet mode. That’s more than enough to cover an entire apartment or small house in one go. Lower-end models may offer slightly shorter runtimes, like M210 Pro, which comes with a 2600mAh battery and up to 120 minutes of runtime, but still outperform many competitors in this price bracket.

Conclusion

Lefant proves that you don’t need deep pockets to go cordless and hands-free. While it doesn’t chase flashy tech like AI object detection or auto-empty docks, it nails the essentials — great suction, long battery life, and tangle-free performance in a compact package.

These bots aren’t made to replace a flagship, but they’re perfect for anyone who wants a quiet helper that just gets the job done. For first-time buyers, pet owners, or small-space dwellers, Lefant hits a sweet spot that few others in its class can match.
