Lefant M210 Robot Vacuum Review: a small, no-frills robo-vac that keeps floors under control

I’ve been using the Lefant M210 in a pretty normal setting: small house, mix of hard floors and a couple of rugs, one shedding pet, and not a lot of time or motivation to vacuum every day. I didn’t buy it expecting miracles, just something that could pick up the daily dust, crumbs and hair without me dragging out the big vacuum all the time. After a few weeks, I’ve got a decent idea of what it does well and where it cuts corners.

The first thing I noticed is that it’s clearly a budget robot, both in price and in how it behaves. There’s no fancy LiDAR tower, no super clever mapping on the first run, and the app is pretty basic. But on the flip side, it’s small, simple, and it genuinely cleans more than I expected for the money. If you’re used to manual vacuuming only, the difference in how often your floors look “acceptable” is pretty obvious after a few days.

I run it mostly in the evening when we’re in another room, and it just wanders around picking up pet hair and crumbs from the day. It’s not smart enough to clean room-by-room in a perfectly logical pattern like higher-end models, but it does eventually cover the area. You can see the dustbin after a run and it’s usually full of hair, grit and random debris I didn’t even notice. So in terms of raw cleaning, it gets the job done, just not in a fancy way.

If you’re expecting a premium robot that replaces all manual vacuuming, this isn’t it. If you want something that quietly handles 70–80% of the daily mess and reduces how often you need to do a deep clean, that’s more the level we’re talking about. It’s not perfect, but for the price bracket and the size, it’s a pretty solid helper, especially in flats or smaller homes with mostly hard floors.

In terms of price versus what you get, the Lefant M210 sits in a pretty sweet spot for basic home use. You’re not paying for fancy mapping, self-emptying bins, or mopping features you might not use. Instead, you get a compact robot that reliably picks up daily dirt and hair, fits under low furniture, and doesn’t need constant babysitting. For someone who just wants to reduce how often they pull out a full-size vacuum, the value is solid.

Compared to higher-end robots that cost two or three times more, you obviously lose some things: precise room mapping, virtual no-go zones, multi-floor maps, stronger carpet performance, and often quieter operation. If those features matter to you, you’ll probably find this model limited. But if you’re like most people I know – living in a flat or small house, mostly hard floors, and just wanting less dust and hair underfoot – those extras are nice-to-have, not essential. The M210 focuses on the basics and does them reasonably well.

Running costs aren’t crazy either. Replacement filters and side brushes are affordable, and there’s no main roller brush to replace or constantly detangle. Power usage is low, and because it auto-docks and charges, you’re not wasting time fiddling with it. The main cost is just the initial purchase and occasional consumables, which feels fair for something that can run several times a week and keep the place looking cleaner with almost no effort.

If you expect this robot to completely replace your normal vacuum and deep-clean carpets, you’ll be disappointed and probably think it’s overpriced. But if you see it as a helper that handles daily crumbs, dust, and pet hair so your manual cleaning sessions are less frequent and quicker, it offers good value. There are cheaper no-name robots around, but many of them have worse navigation, weaker suction, or poor support. Lefant at least has a track record and a lot of user reviews behind this model, which reassured me a bit when choosing it.

The design is pretty straightforward: a low, round white disc with two side brushes up front and a brushless suction opening instead of a traditional roller brush. The 7.8 cm height and 28 cm diameter are actually the standout features. In practice, that low profile means it slides under my sofa, TV unit, and bed without getting stuck, which my older, taller robo-vac simply couldn’t do. If you’ve got a lot of low furniture, this matters more than any marketing about “smart navigation”.

The top lid opens to reveal the dustbin and the power switch, which is both good and slightly annoying. Good because it keeps the design clean and the dustbin easy to access from the top; annoying because if you forget that little switch exists and only use the main button, you’ll think the robot is dead out of the box. The body feels like standard plastic – not premium, not flimsy. I’ve seen it bump gently into chair legs and skirting boards and there’s no visible damage yet, so for normal home use the build seems decent.

On the underside, the lack of a central roller brush is noticeable. It’s basically a suction slot with the two side brushes sweeping debris in. For pet hair, this is actually a plus: there’s way less hair wrapping around anything. On my old robot with a roller, I had to cut hair out of the brush every week. With this one, I mostly just clear hair from the side brushes and empty the bin. The trade-off is that it’s not quite as good at deep cleaning carpets, especially thicker ones, because there’s no brush beating the fibers.

Visually, it’s nothing special. White plastic, simple buttons, basic dock. But from a practical angle, the design choices make sense: small footprint, no overcomplicated parts, and easy access to the parts you actually touch (bin, filter, brushes). If you’re the type who values clean lines and fancy finishes, this will feel a bit plain. If you just want something that fits under the bed and doesn’t need constant fiddling, the design is pretty well thought out for the price level.

The advertised 120 minutes of battery life is roughly accurate, at least on hard floors in standard mode. In my case, with a two-bedroom layout and mostly hard flooring, it can do the entire floor in one go and still come back to the dock with some charge left. If you have a larger house or lots of carpet, the runtime will drop a bit, but it’s still decent for the price. You don’t get multiple power levels to tweak the runtime, which simplifies things but also means you can’t extend battery life by dropping to a lower power mode.

What I like is that it reliably finds its way back to the charging dock when the battery is low. It’s not lightning fast about it, but it usually manages to dock without getting lost, as long as the base is placed in a fairly open area with a bit of space around it. I tried tucking the dock into a tighter corner and it struggled more, so give it at least half a meter of clearance each side if you can. Once docked, it charges back to full in a few hours, and then it’s ready for another run.

One thing to keep in mind: if you have it set on a schedule, make sure the main power switch under the lid stays on. If you turn that off accidentally (for example when cleaning the bin), the robot won’t charge or start as expected and it looks like the battery is dead. That’s more user error than a battery issue, but it’s an easy mistake at the start. Long-term, I can’t say yet how the battery will hold up after a year or more, but so far there’s no sudden drop or weird behavior.

In day-to-day use, the battery is basically a non-issue for small and medium places: you start it, it runs, it comes back. If you have a big multi-room house and want it to clean everything in one long session, you might hit the limit and need to run it in zones or let it recharge in between. But for the target user – flats, smaller houses, or using it per floor – the battery performance is perfectly acceptable.

Durability on a robot vacuum is mostly about three things: how the body handles bumps, how the moving parts cope with hair and dust, and whether anything starts acting weird after a few weeks. So far, the M210 is holding up reasonably well. The plastic shell doesn’t feel premium, but it also doesn’t feel like it’ll crack at the first knock. Mine has bumped into chair legs, metal table feet, and the occasional wall edge, and apart from a few light scuffs, there’s nothing dramatic. The bumper and sensors seem to take the hits as intended.

The big plus for durability is the brushless nozzle design. Because there’s no central roller brush, there are fewer moving parts to clog up or break. Pet hair mostly ends up in the dustbin or occasionally wrapped around the side brushes, which are cheap and easy to replace. On my previous robot with a roller, I had to unscrew and cut hair out of the brush every week, and over time the bearings got noisy. With this one, maintenance is lighter, and that usually means it stays in better shape longer because you actually bother to clean it.

The filter system is basic HEPA-style and does the job. You’ll want to tap it out or vacuum it regularly if you have a lot of dust or pets, otherwise suction will drop. Replacement filters and brushes are easy enough to find online for this model, and they’re not expensive. That’s important, because a robot can be mechanically fine but become useless if you can’t easily keep the consumables fresh. The wheels climb small thresholds and rugs without grinding or making strange noises so far, which is a good sign.

Long-term durability (talking years) is hard to judge after a short period, but based on the simplicity of the design and the lack of fragile extras, I’d expect it to last a reasonable amount of time if you:

• Empty the bin regularly
• Clean or replace filters on schedule
• Clear hair from the side brushes and wheels
• Don’t let it chew on cables or socks

On hard floors, the M210 does a solid job. I’ve tested it on laminate, tiles, and vinyl, and it picks up dust, crumbs, pet hair, and sand without much trouble. The 2200Pa suction rating sounds big, but what matters more is what ends up in the bin, and it’s usually pretty full after a run in my living room and hallway. If I vacuum manually first and then run the robot, it still finds extra grit and fine dust, which tells me it’s not just rolling around pretending to work. The edge mode also helps it follow skirting boards and get the line of dust that usually sits there.

On carpets and rugs, it’s more hit and miss. On low-pile rugs, it’s fine: it climbs them without an issue and picks up surface debris. But without a central roller brush, it doesn’t dig deep into the fibers. If you have thick carpets and expect that “just vacuumed with a big upright” look, you won’t get it from this. It will keep carpets from getting filthy, but you’ll still want to do a proper vacuum every so often. For me, that’s acceptable since most of my place is hard flooring anyway.

Navigation-wise, it’s somewhere between random and semi-structured. The brand talks about FreeMove 3.0 and 6D sensors, and you can see it reacting to obstacles without slamming into them. It avoids stairs and doesn’t throw itself down steps, which is obviously good. But it doesn’t map your house in a smart way like more expensive LiDAR models. The “planning” mode is more about doing passes in a rough pattern than building a perfect map. It may go over the same spot a couple of times and skip an area for a while, but usually, by the end of the run, most of the floor has been covered.

Noise-wise, it’s around 60 dB on paper, and in reality it’s noticeable but not unbearable. You can have a conversation in the same room, but you won’t forget it’s there. If you’re super sensitive to noise, you’ll probably run it when you leave the house or move to another room. Overall, performance is good for daily maintenance: it keeps the general mess under control. Just don’t expect deep cleaning on thick carpets or super smart room-by-room behavior, because that’s where the budget nature shows.

Out of the box, the M210 is pretty straightforward: the robot itself, the small charging dock, power cable, a filter, side brushes, and a simple remote. There’s also the app option and Alexa support, but you can run it just fine with the remote if you don’t care about smart home stuff. I like that it doesn’t come with a ton of useless plastic accessories that end up in a drawer. You plug in the base, charge it up, flip the tiny power switch under the lid to “I” (easy to miss, by the way), and you’re basically ready to go.

The specs say 2200Pa suction, 120 minutes of runtime, 500 ml dustbin, and 7.8 cm height with a 28 cm diameter. In real life, that translates to: decent suction for daily dust and hair, enough battery to do a small to medium floor in one go, and a dustbin you’ll empty every couple of runs if you have pets. The height and diameter matter more than the numbers suggest: because it’s short and narrow, it fits under a lot of furniture that bulkier robots can’t reach. In my case, it gets under the sofa and bed where dust usually collects and never sees a vacuum.

The app is basic but workable. You can switch modes (auto, edge, spot, planning), set a schedule, and start/stop it remotely. It only works on 2.4 GHz Wi-Fi, so if your router is on 5 GHz only, you’ll have to tweak your settings. Setup took me about 10–15 minutes including getting it on Wi-Fi. Once that’s done, you mostly just hit start and let it run. No self-emptying base, no fancy mopping attachment, none of that. It’s a simple vacuum robot, and that’s all it pretends to be.

Overall, the presentation matches the price: it feels like a budget device but not cheap junk. The manual is clear enough, the spare filter and brushes are a nice touch, and you don’t feel like you’re paying for gimmicks you’ll never use. If you’re expecting top-tier navigation or super polished software, you’ll be disappointed, but if you just want a small robot that vacuums, the package is pretty honest.
