A rug is not a small carpet. It has edges the machine has to climb, fringe the brush can eat, and a surface a wet pad must never be dragged across - and those three problems have three different answers.

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.
For a home with area rugs, buy the Roborock Q10 S5+. It is the only machine under $300 whose published specification says the mop lifts 8 mm when ultrasonic detection finds a rug. Every other mopping machine at this price either avoids the rug entirely or drags a damp pad straight across it. Lifting means the robot still vacuums the rug on a mop run. Avoiding means it does not.
This page exists because "can a robot vacuum go over a rug" is one of the questions people actually type, and it is not the same question as whether a robot vacuum cleans carpet. Wall-to-wall carpet is a surface. A rug is an object sitting on a different surface, and objects have edges.

Lefant M330 ProPSD sensors that see cords and small objects, now with dToF mapping behind them. It publishes no suction figure at all, which is the trade.
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.

Three different things go wrong on a rug, and only one of them is suction
Almost every roundup answers rugs by quoting a Pascal figure. Suction is the least of it. Here is what actually happens in a home with rugs, in the order you will encounter it.
1. The machine cannot get onto it
A rug presents a small vertical step. A thin flatweave is a few millimeters and no machine notices it. A bound-edge wool rug with an underlay can be 15 mm or more, and that is a real climb for a five-pound robot on small wheels. When it fails you get one of two outcomes: the robot noses up, slips back and gives up, which is harmless, or it half-climbs, beaches on its center caster and sits there spinning until the battery dies, which is not.
The specification to look for is threshold climbing height, and the uncomfortable truth is that most brands at this price do not publish one. Where a figure is published we have put it in the table below. Where it is not, we have written that instead of guessing.
2. The brush eats the fringe
This is the failure that costs money. Tassels, fringe and a loose bound edge are, from a brushroll's point of view, exactly like long hair - except that they are attached to something. The brush grabs the fringe, winds it in, and then either the machine's overload protection cuts in and it stops, or it keeps pulling and the rug is damaged. On a machine that also has a spinning side brush, the side brush usually gets there first.
There is no clever feature that solves this. Anti-tangle geometry helps with hair because hair is thin and can be cut or shed; a wool tassel is neither. The two real answers are a machine with no brushroll at all, or a no-go zone drawn around the fringed edge - which means you need a machine that can hold a map.
3. The mop gets dragged across it
A vacuum-and-mop robot with a wet pad fitted will, unless it is specifically designed not to, drive onto your rug with the pad down. A damp microfiber pad on wool is not a disaster once. Done twice a week for a year, on a rug that never fully dries between passes, it is how rugs start to smell.
The specification that decides it: what the mop pad does when it meets a rug
There are three published behaviors at this price, and they are genuinely different products, not marketing variations on one idea.
Behavior
What happens on the rug
Machines that publish it
Cost to you
Mop lifts
Ultrasonic detection finds the rug, the pad raises 8 mm, suction increases, the robot drives on and vacuums it
Roborock Q10 S5+ only
Nothing - this is the behavior you want
Rug avoided
The robot detects the rug and refuses to drive onto it while the pad is fitted
Lefant M330 Pro, Lefant N3, Roomba 105 Combo
The rug is not vacuumed at all on a mop run
Neither
The pad is dragged across the rug like any other surface
Most machines at this price, including the Roborock Q7 M5+
You remove the pad by hand, or you keep the robot off rugs
Read from each manufacturer's published listing. A machine that does not state a carpet or rug behavior is assumed not to have one, which is the assumption the listing invites.
The Lefant N3 is worth singling out here because its detection is ultrasonic rather than optical, the same approach the far more expensive Roborock uses. It raises suction and changes direction when it finds pile. It still does not lift the pad, so the outcome is avoidance rather than cleaning - but it is reliable avoidance, which is better than an optical sensor that misreads a dark rug as a dark floor.
Fringe, tassels and the unfair advantage of having no brush
The Lefant M210 and M330 Pro have no roller brush. They pull debris straight into the airflow path through an open inlet. On wall-to-wall carpet this is a real weakness and we say so plainly on the carpet page - with nothing to agitate the pile, they lift only what is sitting on top of it.
On a rug with fringe, the same design is a genuine advantage. There is no roller for a tassel to wind around. At $99 and $120 respectively these are the two machines we would put in a home with several fringed rugs and mostly hard floor between them, and the reasoning is the reverse of the reasoning that keeps them off the carpet ranking.
If you want a brushroll machine anyway - and for a rug with real pile you should - then the answer is a map. Both Roborocks and the Lefant M330 Pro let you draw a no-go zone, and the correct place to draw it is a narrow strip along the fringed edge rather than around the whole rug. The robot still cleans the field of the rug and never touches the tassels.
How thick is too thick, and where this page hands over
Everything above is about rugs the machine can work on. There is a thickness beyond which no robot vacuum in this price range is the right tool, and it is lower than most people expect - roughly medium pile. High-pile and shag rugs should be treated as furniture: draw a no-go zone and vacuum them by hand.
That threshold, and the physics behind it, is covered properly on how thick is too thick and in the longer explanation at do robot vacuums work on carpet. This page assumes you have read that and your rugs are under the line.
Five minutes of setup that prevents most rug problems
Run the first clean with no mop pad fitted and watch it meet each rug. You are looking for whether it climbs cleanly, noses off, or beaches. This tells you more than any specification.
If a rug slides, put a non-slip underlay beneath it. A rug that moves gets bunched into a corner and then climbed, which is how machines get stuck.
Draw a no-go strip along any fringed edge before the second run, not after the first tassel is eaten.
If a rug edge curls, weight it or steam it flat. A curled edge is a ramp into the underside of the rug.
On a machine that avoids rugs while mopping, schedule a separate vacuum-only run with the pad removed, otherwise those rooms are never cleaned.

What it gets right
Structured-light obstacle avoidance is the single feature that separates a machine that finishes from one you rescue. Nothing else under $300 has it
A mop that lifts 8 mm means it can do hard floors and carpet in one run without wetting a rug
3,000 scrubs a minute is an actual scrubbing mechanism, not a damp pad
10,000Pa, dual anti-tangle brushes, multi-level maps - it gives up almost nothing to a $600 machine
What it gives up
The most expensive machine on this site, and it sits close to the ceiling
2.7 L bags are a recurring cost, and 70 days is mid-pack
The dock does not wash the mop - you rinse the pad yourself

What it gets right
PSD avoidance is named for the objects it detects - furniture, cords and small items - which almost nothing else at this price claims
dToF mapping with multi-floor maps, at a price where most machines still have no map at all
An anti-tangle suction port rather than a roller, so there is nothing for hair to wrap around
A 450 ml visible bin, so you can see when it needs emptying instead of guessing
What it gives up
No published Pascal figure anywhere on the listing, so its headline capability cannot be compared with anything
At 95 mm it is taller than the slimmest machines here and will not clear the lowest furniture
The mop is a washable pad on a 200 ml tank - maintenance mopping, not scrubbing
No self-emptying dock, so the bin is yours to empty

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

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
+−Can robot vacuums go over rugs?
Most rugs, yes. A robot vacuum will climb a thin or medium-pile rug without difficulty. It struggles above roughly 20 mm of total thickness including underlay, and high-pile or shag rugs should be treated as no-go zones rather than surfaces to clean.
+−Will a robot vacuum get stuck on my rug?
It can, in two situations: a rug thick enough that the machine half-climbs and beaches on its underside, and a rug that slides or curls so the robot drives under the edge. A non-slip underlay and a flat edge fix almost all of it.
+−Do robot vacuums damage rug fringe?
A machine with a roller brush can. Tassels behave like long hair, except they are attached, so the brush winds them in. A brushless machine such as the Lefant M210 or M330 Pro cannot do this, and on a mapping machine you can draw a no-go strip along the fringed edge instead.
+−Will a robot mop ruin my rug?
Repeatedly, it might. Only the Roborock Q10 S5+ lifts its mop pad when it detects a rug at this price. The Lefant M330 Pro, Lefant N3 and Roomba 105 Combo avoid rugs while mopping instead, which protects the rug but leaves it unvacuumed. Everything else drags the pad across it.
+−What is the best robot vacuum for area rugs under $300?
The Roborock Q10 S5+. It is the only machine here that both lifts the mop and raises suction when it detects a rug, so a single run cleans your hard floors and your rugs properly. If you have fringed rugs and mostly hard floor, the brushless Lefant M330 Pro is the safer and much cheaper answer.
+−Should I use no-go zones for rugs?
For fringed edges and anything above medium pile, yes - and draw the strip along the edge rather than around the whole rug, so the machine still cleans the middle. This needs a machine that holds a map, which rules out the non-mapping options at the bottom of the price range.
