TL;DRThe Short Answer: Is the Lefant Robot Vacuum Worth It?

Dust and pet hair collect under the bed and the sofa, exactly where a taller robot vacuum cannot follow. At under 3 inches high, the Lefant M210 gets there, and in a home with hard floors and a dog it earns its keep running on a schedule every day. It suits tile and hardwood homes with pets that want a simple, low-cost daily vacuum, not a robot that mops or maps rooms. The catch is patience: it can get stuck under low furniture, and its 120-minute runtime is Lefant's low-suction figure.

What Stands Out

  1. 11-inch diameter and 2.99-inch height, designed to fit under beds and sofas
  2. Brushless suction port that, according to the manufacturer, avoids the hair tangling of roller brushes
  3. Up to 120 minutes of runtime in low suction mode, with auto-docking
  4. Six cleaning modes, app scheduling, and Alexa or Google Assistant voice control
  5. 500 ml dust bin, with two HEPA filters and four side brushes in the box
  6. Rated noise level of 52 dB, quiet enough that a dog may not even notice it

Strengths and Drawbacks

What works

  • Picks up a surprising amount of dog hair, dust and crud, even from floors that look clean
  • Slim 11-inch body under 3 inches tall reaches under sofas, beds and even the fridge
  • Copes with the step from tile onto rugs
  • Dust bin is easy to empty, with two HEPA filters and four side brushes in the box
  • Holds its own against robots costing several times as much
  • Lefant's support responds quickly and sends replacement parts

What does not

  • Vacuum only; it does not mop
  • Can get stuck under low furniture such as desks and ottomans
  • The 120-minute runtime applies to low suction mode only, as Lefant notes
  • Suction on the standard setting can be weak on a very dirty floor
  • The app is basic, and its mapping view can be hard to follow
  • Long hair can tangle and pop out the side brushes, despite the brushless suction port

Features in Depth

An Under-3-Inch Body: the Real Reason It Reaches Under Furniture

Item Dimensions 11"L x 11"W x 2.8"H Filter Type Cartridge Clean Modes 6

Lefant puts the M210 at under 3 inches tall on an 11-inch diameter, and that low profile is the single specification that determines whether a robot vacuum can actually clean a room rather than just the open floor of it. Furniture with a low clearance — a bed frame, a low sofa, some kitchen toe-kicks — simply excludes taller robots entirely, and dust and pet hair accumulate exactly there because nothing else reaches it either. Lefant designed this one to work under and around beds and sofas, which is where a bulkier robot stops. Navigation is handled by what Lefant calls FreeMove Technology 3.0, using 6D built-in anti-collision infrared sensors to detect areas the robot could become stuck in and adjust its path, alongside six selectable clean modes — zigzag, random, spot, edge, scheduled and manual control. Lefant also swaps the usual roller brush for a brushless suction port: a digital motor pulls pet hair and dirt straight into the dustbin, so there is no roller for hair to wrap around.

120 Minutes of Runtime, and a Battery Detail Worth Flagging

Battery Life Up to 120 minutes Battery chemistry Lithium iron phosphate Capacity 500 cubic centimeter dustbin

The battery is quoted at up to 120 minutes of runtime, and Lefant specifies a lithium iron phosphate battery, a chemistry generally regarded as more thermally stable and longer-lived across repeated charge cycles than other lithium-ion types, which is a good choice for a device that charges itself daily for years. Expect the 120-minute figure to be the ceiling rather than the average: Lefant quotes it in low suction mode, and running at a higher suction level or across more floor will draw it down faster. Battery life varies in practice. As a rough guide, a 10 by 10 foot room uses about a tenth of the charge, and the robot heads back to its base on its own when the battery runs low.

App and Voice Control, and Lefant's Own Troubleshooting Note

Control App-Lefant, Alexa, Google Home Special Feature Auto-Docking, Scheduling Noise Level 52 dB

Control is handled through Wi-Fi and a dedicated app, with voice commands through Amazon Echo and Google Home. If the M210 won't connect, the fix is usually the app: Lefant's own advice is to use the new App-Lefant rather than the older App-Lefant Life. An outdated or wrong app left over from an earlier purchase is a common cause of pairing trouble with smart home devices, so check that before assuming a hardware fault. The app itself is simple - scheduling, modes, suction level and direction, and sending the robot home - without the detailed room maps of pricier robots. In the box are the robot, a charging base, a power adapter and the dustbin, and auto-docking returns the robot to recharge on its own when a cleaning cycle ends or the battery runs low.

Strong on Pet Hair, Mixed on Reliability, and No Mopping

Strengths Pet hair and hard floors Reliability Varies; drive wheel can jam Mopping None, vacuum only

Cleaning performance, pet hair pickup, low noise and ease of use are its strengths, particularly on hardwood and tile; reliability and battery life are less consistent. One failure worth knowing about is the drive wheel: after about a year of daily use a wheel can jam, leaving the robot spinning in place. Lefant's support handles this well, with quick repair instructions and a replacement part. Lefant describes no mopping function, and it bears repeating: this is a vacuum only, with no water tank or mop attachment, so floors come out clean but not shiny. For hard floors and low-pile carpet with pets in the house it is good value as a dry vacuum; just don't expect it to mop, and contact Lefant promptly if a wheel or motor problem appears.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.1 out of 5 on Amazon, recorded September 26, 2026
How we score
We score each thing that comes up most in owner feedback on the Lefant Robot Vacuum Cleaner. Eight things come up most in owner feedback: six draw praise and two split opinion. Its ratings average 4.1 stars (61% five stars, 17% four, 9% three and 13% one or two), so every score starts at 82, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read six owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.1 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Nothing comes off here, so it stays at 4.1. Read our editorial standards

Setting It Up

  1. Check the box

    In the box: the M210, charging base, power adapter, 500 ml dust bin, two HEPA filters, four side brushes, a cleaning brush and the user manual.

  2. Set up the charging base

    Connect the base with the included power adapter and charge the robot; auto-docking brings it back here after a run.

  3. Install the right app

    Use the newer App-Lefant app; Lefant says the M210 will not connect through the older Lefant Life app.

  4. Link a voice assistant

    Optionally connect Alexa or Google Assistant; linking is usually straightforward.

  5. Set a schedule and mode

    Choose when it runs, the mode and the power level in the app, and do not use Zigzag mode on carpet.

Common Questions

Does the Lefant M210 mop as well as vacuum?

No, this is a vacuum-only robot. Lefant describes no water tank, mop pad or mopping function, so floors come out clean but not shiny and you will still need to mop. If mopping is what you need, look for a model Lefant sells as a combined vacuum and mop.

My M210 won't connect to the app. What should I check first?

Lefant addresses this directly: make sure you are using the new App-Lefant application rather than the older App-Lefant Life, which may no longer support this model correctly. An outdated app left over from a previous search or purchase is a common cause of pairing failures with smart home devices, so check the app name and update it before assuming a hardware fault.

How long does the battery actually last in real use?

Lefant quotes up to 120 minutes, but treat that as the ceiling: Lefant states it applies in low suction mode, so a higher power level or a larger floor area will drain the battery faster. Battery life also varies between units and declines over the life of the battery.

Will it hold up after a year or more of daily use?

Reliability is less consistent than cleaning performance. A known failure after about a year of daily running is a jammed drive wheel that leaves the robot spinning in place, a plausible wear point for any robot that runs unsupervised every day. Lefant's support responds quickly with repair instructions and replacement parts, so get in touch if a similar issue appears rather than assuming nothing can be done.

How strong is the suction?

Lefant pairs a digital motor with a brushless suction port, and you can change the suction level and cleaning direction in the app. It picks up a surprising amount of dust and dog hair, even from floors that looked clean. The standard setting can feel weak on a very dirty floor, so if the first run leaves debris behind, try a higher power level or run it a few times.

Is it actually good for pet hair on hard floors?

Yes. Pet hair pickup and cleaning on wood and hard floors are its strongest points, and Lefant recommends it for wood, hard floor and low pile carpet specifically. This is the use it suits best. On carpet, avoid zigzag mode, which Lefant says not to use there.

The Verdict

4.1Out of 5

The Lefant M210 does the basic job of a robot vacuum well for very little money. Its sub-3-inch body gets under furniture, its brushless port collects a lot of dog hair and dust, and an app schedule keeps floors clean while you are out. The costs are real but modest: it does not mop, it sometimes gets stuck under low furniture, the 120-minute runtime is a low-suction figure, reliability and battery life vary, and the app is basic. For hard-floor homes, especially with pets, it is an easy recommendation.

Who should buy it

  • Homes with mostly hard floors and rugs
  • Dog owners who want to keep up with shed hair between deeper cleans
  • Anyone who wants a first robot vacuum, or a second one for another floor, without spending much
  • People who prefer a simple robot to one with maps and self-emptying stations

Buy it for low-cost, low-effort daily vacuuming on hard floors. If you need mopping, room maps or confidence on wall-to-wall carpet, look elsewhere.
