Mapping is the only feature that changes what the machine is. Everything else on the box is a matter of degree, and the pascal numbers are not comparable at all.
Everyone in this category says they tested twenty vacuums. We have not tested any, and we say so. What we do instead is read the manuals, compile the published specifications, and work out what each machine costs to run for three years — the method is written out in full.
We earn a commission if you buy through the links on this page, at no extra cost to you. It never changes what we recommend or the order we recommend it in. Full disclosure.
The short answer: the iRobot Roomba 105 Vac. It publishes ClearView LiDAR mapping, keep-out zones, 200 minutes of runtime — the longest on this page — and recharge-and-resume, from the manufacturer whose app is the safest long-term bet in the category. If you want the highest published suction figure instead, the Roborock Q7 L5 states 8,000 Pa.
Mapping is the feature. Everything else is a preference.
A robot with LiDAR builds a floor plan, cleans in efficient rows, remembers where it has been and can be told where not to go. A robot without one bounces off things in a semi-random pattern until the battery runs down. On 400 square feet that is a difference in time taken. On 1,200 square feet it is the difference between the far bedroom being cleaned and not.
Four machines here publish full mapping with no-go zones: the Roomba 105 Vac (ClearView LiDAR), the Roborock Q7 L5 (360-degree LiDAR with multi-floor maps), the Lefant M2 Plus and the ILIFE A30 Pro (LDS LiDAR with SLAM). Three do not: the eufy 11S MAX, the Lefant M210 and the Tikom G8000 Max — and they are cheaper for precisely that reason, which is a fair trade rather than a con.
The bin trade nobody mentions
It runs backwards from what you would expect. The cheap unmapped robots often have the bigger bins. The eufy 11S MAX publishes 600 ml. The Tikom G8000 Max publishes 450 ml. The mapped Roborock Q7 L5 publishes 270 ml — less than half the eufy's — and the ILIFE A30 Pro publishes 200 ml because its 2-in-1 tank splits capacity with the water reservoir.
That is logical once you see it: a mapped robot is often sold expecting a dock to empty into, so the on-board bin is a buffer rather than a container. But if you buy a mapped robot without a dock, you have bought the smaller bin and kept the emptying chore. Worth knowing before you order.
What we looked at
Navigation, weighted heaviest, because it is the only feature that changes the class of machine.
Published runtime, and the mode it was measured in — Tikom's 150 minutes is explicitly the quiet-mode figure, ILIFE's is the gentle-suction figure.
On-board bin volume, which varies more than four-fold across this group.
Dock capacity and whether the dock is bagged, because that is the ongoing cost.
Published noise ratings, which range from 45 dB to 72 dB here — a very large spread.
App and parts longevity, which is not a spec and is the biggest real risk on a cheap connected appliance.

Not published
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+200 minutes rated, the longest published runtime of any robot on this site
+Real LiDAR mapping, keep-out zones and room targeting at a budget price
+Recharge-and-resume, so a large floor completes without you
+iRobot's app and parts supply are the most durable bet in the category
Where it stops
−The 70x suction claim is measured against iRobot's own decade-old 600 series, not against a competitor
−No self-empty dock in this configuration — you empty the on-board bin
−No published bin volume
Who it is for
Multi-room homes that want scheduled, mapped cleaning without a self-empty dock's price.
Skip it if
Nobody in the house will install an app. Half of what you are paying for is mapping, zones and scheduling, and none of that exists without the phone.

Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+Publishes a suction figure, unlike most of the field
+Dual anti-tangle brushes — both main and side, which most brands only claim for one
+Multi-floor mapping stored on the robot, so it works in a two-story house
+Vacuums and mops in the same pass
Where it stops
−270 ml dustbin is less than half the eufy 11S MAX's, so it fills fast in a pet home
−Pa figures are not comparable across brands and Roborock does not publish their method
−No self-empty dock in this configuration
Who it is for
Multi-floor homes that want proper mapping and are willing to empty a small bin.
Skip it if
You have shedding pets and no self-empty dock. A 270 ml bin in a dog house is a daily chore, and the Q7 M5+ exists specifically to fix that.

Where it stops
−Emptying a bagless dock does put you back in contact with the dust, HEPA or not
−No published suction figure in any unit
−15.3 lb with the base is the heaviest robot package here
Who it is for
Anyone who has done the maths on dock bags over five years and did not like the answer.
Skip it if
Allergies are the reason you are buying a self-empty robot at all. A bagged dock is the better answer for that specific problem, even though it costs more to run.

+Carpet detection lifts or avoids depending on whether the mop holder is fitted
+Dual-band Wi-Fi — the only robot here that does not force you onto 2.4 GHz
+Two dock bags in the box
Where it stops
−6,000 Pa is the lowest published suction of the self-empty machines here
−250 ml on-robot bin is tiny, which the dock only partly excuses
−Small brand: app longevity and dock-bag availability in year four are unknowns
Who it is for
Buyers who want self-emptying at the lowest possible entry price and accept the brand risk.
Skip it if
You want the app to still work in 2032. iRobot and Roborock are safer bets on software support, and a self-empty robot is worthless once its dock bags stop being sold.

Not published
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+600 ml bin, the largest on-robot bin here, which matters when there is no self-empty dock
+55 dB rated, quiet enough to run while you are in the room
+2.85 inches tall, so it fits under more furniture than most
+No app means no account, no firmware updates, and nothing to stop working when a server retires
Where it stops
−No mapping — it cleans in a semi-random pattern and takes longer to cover a room
−No no-go zones, no room targeting, no scheduling from a phone
−Single side brush
−No published suction figure at all
Who it is for
One-floor apartments, mostly hard floor, where the job is daily dust and pet hair rather than a scheduled whole-house clean.
Skip it if
You have more than about 800 square feet or several rooms. Without mapping it will miss areas, and you will not be able to tell it not to.

Where it stops
−No brushroll also means no agitation, so carpet pickup is weak by design
−The 120-minute figure is explicitly the low-suction number
−No LiDAR mapping
Who it is for
Hard-floor homes with long-haired occupants or pets, and anyone who has cut hair off a robot brushroll once too often.
Skip it if
You have carpet you actually want cleaned. Without a brushroll it lifts surface debris and leaves embedded grit; this is a hard-floor machine.

+450 ml bin plus a 300 ml tank, both larger than the mapped Roborock Q7 L5's

Where it stops
−No mapping, so coverage is a zig-zag pattern rather than a plan
−5,000 Pa is the lowest published figure of the mopping robots here
−The 150-minute rating is the quiet-mode number
Who it is for
Small hard-floor homes, light sleepers, and households that want a remote rather than an app.

The one to skip
Skip the Lefant M210 if you have carpet. Its brushless suction port is a genuinely clever answer to hair tangle — there is nothing for hair to wrap around, which is the only complete fix anyone offers — and at 52 dB and 2.99 inches tall it is a lovely little machine on hard floor. But no brushroll also means no agitation, and without agitation a robot lifts surface debris off carpet and leaves the embedded grit exactly where it was. Buying it for a carpeted house is buying the wrong tool.
A second, softer skip: be careful with the very cheap self-emptying robots if you need the app to work in a decade. The Lefant M2 Plus and the ILIFE A30 Pro both publish excellent hardware sheets at low prices. What neither can publish is how long the cloud service behind the app will run, and a self-emptying robot whose dock bags stop being sold is worth nothing.

Dock bags, unless the dock is bagless
Note that the cheapest tier is both the quietest and has the biggest on-board bin. It is genuinely better at two things.
Above $400 you are buying higher published pascals, obstacle cameras, mop plumbing and heated dock washing. Those are real features. They are also more parts, more app surface and more to fail, and none of them changes the fundamental limitation covered on our carpet page.
What we cannot tell you
How well any of these actually navigate a real house. Published LiDAR is not the same as good path planning, obstacle avoidance quality varies enormously between implementations, and nobody publishes a coverage-efficiency figure. We also cannot tell you how long the app will be supported — the most important unpublished fact about every connected robot here. Our method page sets out exactly where our evidence ends.
Common questions
What is the best budget robot vacuum?+−
On published specifications, the iRobot Roomba 105 Vac: ClearView LiDAR mapping, keep-out zones, 200 minutes of rated runtime and recharge-and-resume. For the highest published suction figure at a similar price, the Roborock Q7 L5 states 8,000 Pa — though pascal figures are not comparable between brands.
Do I need LiDAR mapping on a robot vacuum?+−
Above roughly 800 square feet, yes — it is the difference between planned coverage and a random walk. Below that, an unmapped robot with a bigger bin and a lower noise rating is a defensible and cheaper buy.
Are higher Pa numbers better on a robot vacuum?+−
Not across brands. Pa measures sealed static pressure, every manufacturer measures it differently, and none publish the method. It is only useful for ranking models inside one brand's own range.
Which budget robot vacuum is quietest?+−
On published ratings, the Tikom G8000 Max at 45 dB, then the Lefant M210 at 52 dB and the eufy 11S MAX at 55 dB. All three are unmapped machines — the mapped robots on this page rate 60 to 72 dB.
Can I get a robot vacuum without an app?+−
Yes, and eufy publishes it plainly: the 11S MAX has no Wi-Fi and no app at all, operating on a remote control and on-device buttons. That is a genuine feature if nobody in the house wants another account or another firmware update.
Do budget robot vacuums work on carpet?+−
On low and medium pile they lift surface debris. Embedded grit in deep pile needs agitation and airflow that no robot on this page publishes figures to support — and a brushless design like the Lefant M210 has no agitation by construction. Our dedicated carpet page covers this properly.
