One brand gives you a slim, network-free machine and nothing else. The other gives you a map, a mop and a dock for similar money. The right answer depends on one question about your home.

We have not tested these machines. Everything here comes from published specifications, manufacturer manuals and retailer listings, all cited below. Prices last verified September 21, 2026.
How this is funded: if you buy through a link here we may earn a commission, at no extra cost to you. It does not change which machines we recommend or what we say about them. Full disclosure.
Buy Lefant unless you specifically want a machine that connects to nothing. Lefant's ladder runs from the M210, a brushless machine at the bottom of this site's price range, up to the N3 with dToF LiDAR mapping and a sonic mop. eufy's sub-$300 offering is the 11S MAX, which at 2.85 inches is the slimmest machine on this site and has no Wi-Fi and no app at all - a genuine feature for one kind of buyer and a hard limit for everyone else.
Both brands sit in the same search results and they are not really competing for the same buyer. Here is the question that separates them.

eufy 11S MAXNo Wi-Fi, no app, no account. A remote control and two buttons. For a specific kind of buyer that is the feature, not the limitation.
Lefant N3A sonic mop that vibrates 12,000 times a minute, which is a genuinely different mechanism from the damp cloth every other machine at this price drags around.
Lefant M210A brushless suction port instead of a roller brush, which is why it handles hair better than machines twice its price. It has no map and never will.
Both machines scored on the published rubric from How We Pick: suction 25%, navigation 25%, pet hair 20%, running cost 20%, setup 10%. Editorial judgments about published specifications, not test results.
The one question that decides it
Do you want a map? Everything else follows from that answer.
A map is what gives you keep-out zones, room selection, scheduling from your phone, systematic row-by-row coverage and a machine that resumes where it stopped. The eufy 11S MAX has none of those and cannot be updated to have them, because eufy states on its own listing that it does not support Wi-Fi or app connectivity. The Lefant N3 has all of them.
If the answer is yes, this comparison is over and the only remaining question is which Lefant. If the answer is genuinely no - because you are buying for someone who will never open an app, or because you want nothing in your house talking to a server - then the eufy is not a compromise, it is the specification, and our no Wi-Fi ranking is the page to read next.
Buy eufy if
Furniture clearance is the constraint. 2.85 inches is the slimmest body on this site. If the gap under your sofa is why your floor is dusty, this is the machine that fits under it.
You want no account, no app and no cloud service. Nothing to pair, nothing to update, nothing that can be discontinued underneath you.
You are buying for somebody else who would rather press a button on a remote than install anything.
Build quality matters at the margin. eufy fits a tempered glass top, and after two years of being kicked under a sofa that is not nothing.
Buy Lefant if
You want mapping, which under $200 means the N3 and its dToF LiDAR - a sensor unaffected by ambient light, which cheaper LiDAR is not.
You want mopping that is a mechanism rather than a drag. The N3 publishes 12,000 sonic vibrations a minute; eufy's machine does not mop at all.
You want the lowest price on this site. The M210 is the cheapest machine we rank, and its brushless inlet handles hair better than machines costing twice as much.
Floor-level clutter worries you. Lefant publishes FreeMove obstacle language on both machines; eufy publishes infrared obstacle sensing, which is the tier below.

On price, and why this page does not quote one
Both brands discount hard and independently, and the eufy in particular has moved by a wide margin inside a single week while this site's price layer watched it. Any article that tells you which of these is the cheap one is telling you what was true on the day it was written.
So use the live prices on this page, and apply the rule instead: if the eufy is clearly cheaper, it is a legitimate budget machine for a small hard-floor home, bought for the slim body and the absence of an app. If they are close, the eufy stops being the cheap option and becomes the specialized one - at which point the mapped Lefant is more machine for the same money, and the under $200 band page shows what else that money reaches.
Where neither of them does well
Neither publishes a suction figure you can rank across brands - eufy publishes none at all for the 11S MAX, and Lefant publishes none for the M210 while publishing 4,000Pa for the N3, the lowest figure of any LiDAR machine on this site.
Neither has a self-emptying dock in this comparison. Both are machines whose bins you empty yourself, which with a shedding pet is a twice-weekly job. If that is your situation, the self-emptying ranking is a better starting point than either brand here.
Neither publishes a battery cycle count, so neither will tell you what year three looks like.
Which we would actually buy
For a small hard-floor home where somebody wants mopping and a map: the Lefant N3. For the absolute lowest price with a shedding pet on hard floors: the Lefant M210 and its brushless inlet. For a buyer who wants a machine that connects to nothing, or the slimmest body available: the eufy 11S MAX, and no other machine on this site serves that person at all.
No Wi-Fi, no app, no account. A remote control and two buttons. For a specific kind of buyer that is the feature, not the limitation.

What it gets right
2.85 inches is the slimmest machine in this entire field - it goes under furniture nothing else here clears
No app means no account, no firmware update that breaks it, and no cloud service to be discontinued
BoostIQ raises suction within 1.5 seconds when it meets carpet, without you asking
Tempered glass top, which after two years of being kicked under a sofa is not nothing
What it gives up
eufy publishes no Pa rating on this listing, so its headline capability is unrankable
No app also means no scheduling from your phone, no map, no room selection, no history
100 minutes is the shortest runtime here
A single side brush covers edges more slowly than a dual-brush machine

Who it is for: A small hard-floor home, or anybody buying for someone who will never open an app.
Skip it if: you want to start a clean from work, or you want a cleaning history. This machine deliberately does not connect to anything, and no update will change that.
A sonic mop that vibrates 12,000 times a minute, which is a genuinely different mechanism from the damp cloth every other machine at this price drags around.

Runtime
Up to 200 minutes; manufacturer states 3,200 sq ftSource: Manufacturer listing
Carpet detection
Ultrasonic, raises suction and changes direction in mop modeSource: Manufacturer listing
What it gets right
Sonic scrubbing actually agitates dried-on marks instead of spreading them, which a passive pad cannot do
dToF is a better sensor than the bare LiDAR most machines at this price use - it is unaffected by ambient light
200 minutes and a claimed 3,200 sq ft covers a whole house in one run
Ultrasonic carpet detection means it stops wetting rugs without you drawing zones
What it gives up
4,000Pa is the lowest published figure of any LiDAR machine here
A 160 ml tank is small - a large hard-floor area will need a refill mid-run
No self-emptying dock
Sonic mopping consumes battery faster than a passive pad, so 200 minutes is the vacuum-only figure

Weights and the arithmetic behind the total are published on How we pick so you can recompute this yourself.
Who it is for: Hard floors that actually get dirty - a kitchen, a hallway, a house with children.
Skip it if: your floors are mostly carpet. You would be paying for a mopping mechanism you cannot use and taking the weakest suction figure in the LiDAR group to get it.
The brushless inlet has nothing for hair to wrap around, so there is no brushroll to cut free every fortnight
2.99 inches tall clears most sofa and bed frames that stop taller machines
Lithium iron phosphate cells, a chemistry that tolerates daily full cycles better than the usual lithium-ion
Nothing to subscribe to and no dust bags to buy
What it gives up
No published suction rating at all, which for a machine sold on suction is a strange omission
No mapping. It covers a room by bouncing around it, so a large floor plan takes several passes
The manufacturer says not to use zigzag mode on carpet, which rules out its most efficient pattern on rugs
Brushless inlets are weaker on embedded carpet grit than a beater bar

Who it is for: A one-bedroom apartment with hard floors, a shedding pet, and a hard budget ceiling under $100.
Skip it if: you have more than about 800 square feet of open floor, or any medium-pile carpet you actually want cleaned rather than skimmed. Without a map it will miss areas, and without a brushroll it will not dig.
Questions people actually ask
+−Is Lefant or eufy better?
For most homes, Lefant - it offers mapping, mopping and a wider range under $300, while eufy's machine at this price has no app, no map and no mop. eufy is the better buy for two specific needs: the slimmest body on this site at 2.85 inches, and a machine that works with no network at all.
+−Does the eufy 11S MAX have an app?
No. eufy states on its own listing that the 11S MAX does not support Wi-Fi or app connectivity - it runs from a remote control and the buttons on the machine. For some buyers that is exactly the reason to choose it.
+−Which is better for pet hair, Lefant or eufy?
The Lefant M210, and for an unusual reason: its brushless suction inlet has no roller for hair to wrap around, so there is nothing to cut free. eufy's machine uses a single side brush and publishes no anti-tangle claim.
+−Is the eufy 11S MAX worth it over a mapped Lefant?
Only if you actively want a machine with no app, or you need the 2.85-inch body to fit under furniture. On every other measure a mapped machine at similar money cleans better, because it covers your floor systematically rather than by pattern.
+−Which brand is more reliable?
Neither publishes reliability data, so nobody can answer that honestly. eufy is the more established name; Lefant fits more hardware per dollar and publishes a one-year warranty with weekday support. We record what each publishes rather than guessing at failure rates.
+−Have you tested these machines?
No. Every figure here is read from each manufacturer's own listing and cited below, and the pages for each machine carry an explicit list of the claims we could not check.
