Hardwood needs a soft roller brush, a washing mop dock and controlled water — not high suction. The eufy Omni C28 pairs a self-washing roller mop with a five-function station, though eufy publishes no mop lift for it. Dreame's X40 Ultra removes its pads entirely for mixed floors. Roborock's Qrevo Pro states hot-water pad washing at the lowest price here.
Hardwood is the surface robot vacuums are best at, which is exactly why choosing one for it is harder than it looks. Almost anything will pick dust off a smooth floor, so the suction figure that separates machines on carpet separates nothing here. The differences that remain are about what the brush does to debris it does not collect, what the mop does with dirty water, and what both do to the finish over several years.
On a hard floor, the brush can make things worse
A brush designed to dig into carpet pile has nothing to dig into on a plank floor. Stiff bristles meet a fragment of cereal, flick it two feet sideways out of the robot's path, and the machine drives on. You end up with debris redistributed into the corners and along the skirting rather than in the bin — the specific complaint people describe as the robot just pushing things around.
Soft rollers and rubber-fin brushes do not do this. They make contact across a wider footprint, they deform rather than strike, and debris ends up in the airflow instead of airborne. The construction each maker publishes is the thing to read.
Published brush construction, by model
3 of 4 models publish this figure. Every number below links to the page it came from.
Compiled from the manufacturers’ own published material — every row carries the date its figure was read. We have not measured any of these figures ourselves, see how we pick. Found an error? Tell us and we will correct it.
Note the Qrevo Pro's row and the 105 Vac's row. Roborock publishes no brush construction at all for the Qrevo Pro, and iRobot publishes a bristle brush for the 105 — on a hardwood floor that is the construction most likely to scatter. The cross-brand version of this argument, with the physics in more detail, is in brush types for hardwood and tile.
The mop is doing most of the work
On carpet, mopping is a liability to be lifted out of the way. On hardwood it is the point. Dry vacuuming lifts the crumbs and the visible dust; the film of footprints, paw marks and kitchen grease that makes a wood floor look dull comes up only with water and a pad that is clean enough to absorb it.
That makes the dock the deciding component, exactly as it is on the mop combo roundup. A dock that scrubs the pad, extracts the dirty water and dries the pad with warm air is doing something a human with a bucket does between rooms. A dock that only charges the robot is not.
Edges are visible on wood and hidden on carpet
Fitted carpet hides the strip along the skirting board. A plank floor shows it as a distinct gray line, and it is the first thing people notice when a robot has been running for a month. Every maker here has some answer — an extending side brush, an arm that reaches into the corner, a mop pad that swings out — and almost none of them publishes a figure for how far it reaches.
That is a genuine gap rather than an oversight we can fill. We are not going to estimate a reach in millimeters that no maker states. What we can say is that the models which name the mechanism, like Roborock's FlexiArm family and Dreame's extending side brush, are describing hardware that exists, and the models that describe edge cleaning only in adjectives are not.
Scratching, in proportion
The fear that a robot vacuum will scratch a wood floor is common and mostly misplaced. The wheels are rubber, the body clears the floor, and the brush is softer than the finish. What actually causes marks is grit trapped under a wheel or a caster, dragged repeatedly along the same line — which is an argument for running the robot often rather than for not running it.
The real exceptions are worth knowing: a dock parked on a soft finish, a caster wheel that has picked up a stone, and anything hard the robot pushes rather than collects. Will a robot vacuum scratch your floor goes through each of those and what to check.
How we picked
Criteria first, products second. These are the things we ranked on, stated before anything is recommended.
A soft roller or rubber-fin main brush rather than stiff bristles. On a hard surface the brush has nothing to dig into, so a stiff one flicks debris ahead of the machine instead of collecting it.
A dock that washes the mop pad, because on hardwood the mop does most of the real cleaning and an unwashed pad is redistributing by the second room.
A published mop-lift height for any rug the route crosses, and a published water-control claim, since standing water is what damages a wood floor.
Edge and corner behavior — an extending side brush or arm, because a hardwood room shows the dust line along the baseboard that a carpet hides.
Published figures generally. On a surface this forgiving, a maker's willingness to state numbers is the most useful signal left.
What we did not do: test any of these machines. We do not own one, we do not have a lab, and nothing on this page is written as though we did. The full method.

What it does well
HydroJet roller rinses itself during the run instead of only at the dock
A stated 15,000 Pa, which is a real figure rather than a multiple
Five-function station: mop washing, hot-air drying, dust emptying, tank refill and wastewater collection
What it does not
No published threshold height and no published mop-lift height
No published runtime, bin capacity or body height either
The roller is a consumable and eufy does not state a replacement interval
Who it is for
Hard floors that get genuinely dirty, on a budget that will not reach a flagship omni station.
Skip it if
Your home has thresholds or deep carpet. eufy publishes no climb height and no mop-lift height for this model, so you cannot check either before you buy.
It is an excellent machine and the best answer on this site to a different question — getting under low furniture, where its 80mm body and solid-state navigation genuinely earn the money. On a flat hardwood floor you are paying flagship price for clearance you do not need, and Roborock publishes no threshold height for it at all. If your hardwood runs level through the house, the mid-price models above do the same job on the same floor.
If your hardwood is not the only surface
Most houses with wood floors also have a rug, and the moment a rug enters the route the ranking changes — the mop-lift height stops being a detail and becomes the first thing to check. If that is you, read best robot vacuums for hard floors and area rugs, which ranks on exactly that.
And if the wood is laminate rather than solid timber, the water question is sharper still, because a laminate seam that swells does not sand back. Best robot vacuums for laminate floors covers that case specifically.
Questions people actually ask
+ What is the best robot vacuum for hardwood floors?
The eufy Omni C28 is the straightforward answer on mechanism: a DuoSpiral detangling brush and a station that washes and dries the pad. Be clear about the limit, though - eufy publishes no mop lift height for it, so you cannot check before buying how far the wet pad clears a rug. If your floors are mixed with rugs, the Dreame X40 Ultra is the stronger pick because its pads come off entirely rather than lifting.
+ Do I need high suction for hardwood floors?
No. Debris sits on top of a hard surface rather than being gripped by pile, so it lifts with very little airflow. The 7,000 to 8,000 Pa models here do the job on wood as well as the 22,000 Pa ones. Suction earns its money on carpet, which is why our carpet roundup ranks on it and this one does not.
+ Will a robot vacuum scratch my wood floor?
Very unlikely from the machine itself — rubber wheels, a soft brush and a body that clears the floor. The realistic risk is grit caught under a wheel and dragged, which is an argument for running it regularly rather than avoiding it. Check the casters occasionally and keep the dock off a delicate finish.
+ Can a robot mop damage hardwood?
It can if the floor is unsealed or the water control is poor, because standing water in a board seam swells the edge. Choose a model that states water-level control and hot-air pad drying, and check your floor type first — unsealed wood should not be wet-mopped by anything, robot or human.
+ Why does my robot vacuum push crumbs around on wood?
Almost always a stiff bristle brush. With no pile to dig into, the bristles strike debris and flick it clear of the intake instead of sweeping it in. A soft roller or rubber-fin brush does not have this failure, and it is the main reason we rank brush construction first on this page.
+ Do robot vacuums get the edges of a wood floor?
Partially. Every model here has an extending side brush or an arm of some kind, but no manufacturer publishes how far it actually reaches, so the honest answer is that you should expect to do the skirting line by hand occasionally. The gap shows up more on wood than on carpet simply because you can see it.
