A robot vacuum will chase every crumb under the kitchen table and still glide straight over the sticky ring where a juice glass tipped. Suction lifts what is loose. It does nothing about anything already dried onto the floor, and that one gap decides which machine belongs in your hallway.
Shop this category and you will notice something quickly: mop-only robots barely exist any more. The live decision is between a vacuum-only robot and a vacuum-and-mop combo, and the plain answer turns on your floors, your tolerance for dock maintenance, and whether wet cleaning is a weekly chore or a daily one. The five machines below cover both camps, from a stripped-back mapper to a dock that washes and dries its own pads.

How to choose between a vacuum and a vacuum-mop combo
Match the machine to your floors, not to the spec sheet
Carpet and rugs only ever need suction, so a combo buys you nothing there except a mop module to store. Tile, vinyl, sealed timber and laminate collect a thin film that suction cannot touch, and that is where wet cleaning earns its keep. A home that is mostly hard floor is the clearest case for a combo. A home that is mostly carpet is the clearest case against one.
Suction numbers are real, but they scale oddly
Pascals measure sealed suction, and the figures in this group run from 4,000 Pa on the eufy C10 up to 18,500 Pa on the Qrevo S Pro. More helps on deep pile and embedded pet hair. It helps far less on a bare tile floor, where the brush does most of the work and anything above a moderate figure is already lifting the crumbs. Take a big Pascal number as headroom for carpet, not as a general quality score.
The dock is what you actually live with
This is the part buyers underestimate. A basic charging dock asks you to empty a small bin every run or two. A self-emptying dock, like the ones on the Q10 S5+, the Shark and the eufy C10, drops that to swapping a bag every couple of months. A washing dock goes further and cleans the mop pads for you. Skip that step and a combo becomes a chore: a wet pad left sitting turns sour fast, and hand-rinsing it after every run defeats the point of buying a robot.
Mop lifting and carpet detection are not optional
Any combo that mops a carpet has failed. The fix is a module that lifts when carpet is detected, and lift height is the number to check: the Q10 S5+ raises its pad about 8 mm, the Qrevo S Pro about 10 mm. That is enough for low pile and most flatweaves. Thick shag still needs a no-go zone drawn in the app, whatever the marketing says.
Hair, brushes and the maintenance you inherit
Long hair and pet fur wrap around a bristle brush and turn into two weeksly job with scissors. Rubber or comb-style brushes, like the anti-tangle designs on both roborock units and Shark’s self-cleaning brushroll, cut that down sharply. If anyone in the house has long hair, this matters more day to day than suction does.
Obstacle avoidance is really a tidying tax
Every robot here maps with LiDAR, so none of them wander blindly. The difference is what happens when they meet a sock. Structured-light and camera-based avoidance, as on the Q10 S5+ and the Roomba 105X, steers around cables, shoes and toys instead of dragging them across the room. Weaker systems bump and shove. The practical effect is how much you have to tidy before pressing go: good avoidance means a quick scan of the floor, poor avoidance means picking up every cord first. Nobody keeps using a robot they have to prepare the house for.
Clearance decides where it can reach
Measure under your sofa and bed before you buy. The eufy C10 is 2.85 inches tall and the Qrevo S Pro is 3.8 inches, and that inch is the difference between cleaning under the furniture and drawing a polite line around it. Docks need their own space too, and washing docks are the bulkiest of the lot.
roborock Q10 S5+: the combo that sells the hardest
The Q10 S5+ is the best-selling machine in this group by a wide margin, and the reason is that it refuses to pick a side. It vacuums at 10,000 Pa, which is real carpet suction, and it mops with a sonic module that vibrates the pad up to 3,000 times a minute rather than dragging it. Ultrasonic carpet detection lifts that pad 8 mm on the way onto a rug. The dock swallows 2.7 liters of debris, which roborock rates at roughly 70 days between bag changes, and LiDAR handles multi-floor mapping. It is the middle of the range on price and close to the top on capability, which is a rare place to land.
Pros:
- Strong 10,000 Pa suction, enough for embedded pet hair in carpet
- Sonic mopping scrubs rather than smears
- Automatic mop lifting with ultrasonic carpet detection
- Around 70 days of hands-free operation from the sealed bag
- Anti-tangle comb brush and side brush
Cons:
- The dock does not wash or dry the pad, so that stays your job
- Self-emptying stations are tall and noisy in the moment they run
Best for: mixed carpet and hard floor homes that want one machine to handle both without paying premium money.
Shark AV2501S AI Ultra: methodical vacuum, no mop
Shark’s answer to patchy coverage is to stop cleaning in single passes. Matrix Clean walks a grid over an area and crosses it repeatedly, which is slower but noticeably better on ground-in debris than one lap of a room. There is no mop here at all, and the machine is better for it: the bin is all bin, the base holds a month of dirt behind a HEPA filter rated to trap fine dust and allergens, and the self-cleaning brushroll deals with hair without intervention. Runtime stretches to about two hours, with recharge and resume for larger floorplans.
Pros:
- Grid-pattern multi-pass cleaning covers stubborn areas properly
- Bagless self-empty base with true HEPA filtration
- Self-cleaning brushroll handles pet hair
- Up to 120 minutes of runtime, then recharge and resume
- LiDAR mapping works in the dark
Cons:
- No mopping function of any kind
- Multi-pass grid cleaning takes longer per room
Best for: carpet-heavy homes, allergy-conscious households, and anyone who would rather mop by hand than manage a wet pad.
eufy C10: the one that fits under the furniture
At 2.85 inches the C10 is the flattest machine here, and that is a genuine feature rather than a spec-sheet flourish. Low sofas, bed frames and the gap under a media unit are exactly the places dust collects and taller robots politely decline. The other clever touch is an extending side brush that reaches out into corners instead of relying on the body to get close enough. Suction is the mildest of the group at 4,000 Pa, so deep carpet is not its strength, and there is no mop. The 3 liter bag runs about 60 days.
Pros:
- 2.85-inch body reaches under low furniture others cannot
- Extending corner brush pulls debris out of edges
- Self-empty station with roughly 60 days of capacity
- LiDAR mapping with scheduling and zone control
Cons:
- 4,000 Pa is modest for thick carpet
- Vacuum only, and 2.4 GHz Wi-Fi only
Best for: hard floors and low-pile rugs in homes with a lot of low-clearance furniture.
iRobot Roomba 105X: mapping without the dock tax
The 105X is the cheapest way into this list and it gets the important part right: it maps. ClearView LiDAR builds a plan of the house and cleans in tidy rows, so you get room-by-room targeting, no-go zones and repeatable coverage rather than a robot bouncing off baseboards at random. The trade is the dock. There is no self-emptying base, so the onboard bin is yours to tip out regularly. Suction is quoted at 70 times the old 600 series, the three-stage system pairs a multi-surface brush with an edge sweeper, and obstacle avoidance works in low light.
Pros:
- Real LiDAR mapping and room-by-room control at the lowest price here
- Three-stage cleaning with a multi-surface and edge-sweeping brush
- Navigates and avoids obstacles in the dark
- Recharges and resumes without being asked
- No dock bags to buy, and a small footprint
Cons:
- No self-emptying base, so the bin needs frequent attention
- No mopping
Best for: a first robot, a flat or a single floor, or anyone who wants smart mapping without dock upkeep and consumables.
roborock Qrevo S Pro: the dock does the dirty work
This is the machine that answers the strongest argument against combos. Its dock washes the spinning mop pads at 167 degrees Fahrenheit after a run and then dries them with warm air, so nothing damp sits waiting to smell. Suction is the highest here at 18,500 Pa, the mops lift 10 mm for carpet, and a 3.8-inch body still slides under most sofas. It empties into a sealed bag rated at seven to nine weeks. The cost is money and floor space, and the dock plumbing is one more thing that needs occasional cleaning itself.
Pros:
- Hot-water mop washing and warm-air drying, fully hands-free
- Highest suction in this group at 18,500 Pa
- 10 mm mop lifting with per-carpet cleaning strategies
- Anti-tangle rubber brush and side brush for pet homes
- Quiet in normal use at around 55 dB
Cons:
- Premium price and the largest dock footprint here
- The washing dock itself needs periodic cleaning
Best for: hard-floor homes with pets or kids where the floor gets wet-cleaned several times a week.
The verdict
Best overall: roborock Q10 S5+. It is the clear best seller of this group, and it sits at the point where the vacuum-versus-combo argument stops mattering: 10,000 Pa for carpet, a sonic mop that lifts itself out of trouble, and about 70 days between bag changes, all at a mid-range price. You give up dock-side mop washing, and that is the real catch.
Best value: iRobot Roomba 105X. LiDAR mapping and orderly row cleaning for budget money is a good trade, provided you accept emptying the bin yourself. For a flat or a single floor it does the daily job.
Best premium: roborock Qrevo S Pro. If you want mopping to be genuinely hands-free, the washing and drying dock is what you are paying for, and nothing else here offers it.
The short version: mostly carpet, buy the vacuum. Mostly hard floor and mopping often, buy the combo with the best dock you can justify. Somewhere in between, the Q10 S5+ is why it outsells the rest.
FAQ
Does a robot mop actually clean, or just move dirt around?
It cleans, within limits. A robot mop lifts the light film of dust, footprints and dried splashes that builds up on hard floors between deep cleans. What decides the result is pressure and pad hygiene: a vibrating or spinning pad that gets washed after each run does real work, while a damp cloth dragged behind a robot mostly redistributes. None of them scrub grout or shift baked-on grease. Take mopping as maintenance between proper cleans, not a replacement for them.
Will a combo unit soak my carpet?
Not if it detects carpet and lifts the pad, which every combo in this comparison does. Check the lift height rather than the promise: 8 to 10 mm clears low pile and flatweave rugs comfortably. Deep or shaggy carpet is beyond any of them, so mark it as a no-mop zone in the app and let the robot vacuum it instead.
Is a self-emptying dock worth the extra money?
For most people, yes, and it is the upgrade with the most obvious daily payoff. A robot bin is small, and emptying it every run or two is the chore that quietly kills enthusiasm. A dock turns that into a bag swap every one to two months, and sealed bags keep dust out of the air, which matters if anyone has allergies. The ongoing cost is the bags themselves.
Do I still need a regular vacuum?
Yes, for stairs, upholstery, car interiors and the tight corners a round robot cannot fully reach. What changes is frequency. A robot running daily keeps the floor at a level that used to take a weekly push around, so the upright comes out for occasional jobs instead of routine ones.
What if someone in the house has long hair?
Prioritize the brush design over everything else. Bristle brushes wrap hair into a solid collar that needs cutting free; rubber or comb-style brushes, like the anti-tangle systems on the roborock models or Shark’s self-cleaning brushroll, shed most of it into the bin instead. This single feature makes a bigger difference to how long you keep using the robot than any suction figure.
