All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | eufy Omni S2 |
|---|---|
| Home size | |
| Under 1,500 sqft | GoodCapable but exceeds compact-home needs; premium automation goes underused in smaller spaces. |
| 1,500 – 3,000 | GoodCovers multi-floor homes efficiently; 130-minute runtime sufficient with resume capability. |
| Over 3,000 | GoodDesigned for large spaces; scheduled multi-zone runs or persistent operation handles coverage. |
| Primary floors | |
| Hard floors | GoodCore design and roller-mop system optimized for hard-floor homes. |
| Low / medium pile | Good30,000 Pa and roller-mop suit low carpet; hot-wash drying reduces moisture accumulation. |
| High pile / shag | PoorSuction and low-pile-optimized mop poor match for shag or high-pile; coverage suffers. |
| Mopping needs | |
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. |
| Light mopping | GoodActive mopping system covers routine floors easily. |
| Frequent mopping | GoodPressure or rotating mop with self-wash is built for frequent mopping. |
| You want to… | |
| Empty bin myself | GoodDock automation handles most consumables, but water-line inspection and gasket checks require quarterly attention. |
| Empty occasionally | GoodAutomated dock cycles reduce hands-on work; seasonal dock service needed. |
| Set-and-forget | Depends12-in-1 dock minimizes consumable touch, but heating-element and water-seal failures may demand repair intervention. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
eufy Omni S2
12-in-1 dock: solves every consumable task (empty, wash, dry, dispense), but spreads failure risk across electronics, pumps, tanks and thermal systems that need repair.
Hot-water washing with hot-air drying: eufy heats the wash water (70 C, listed as 140 F in US material) and dries the roller with 131 F air, which is what keeps a mop from souring between runs. It is also close to the whole of the $1,599 argument, and stations that dry with unheated air address the same problem more slowly for less.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
eufy Omni S2
- Deep shag beyond the mop's lift
- The roller mop lifts 28 mm clear of the floor when carpet is detected, more than double the 13 mm on the S1, so ordinary and thick pile are isolated automatically. Pile deeper than that lift is the case the mechanism does not cover.
- Budget-conscious buyers
- $1,599 MSRP puts this at the top of the category, and consumables are the other half of the figure: eufy suggests a new roller mop every two months at $26.99, roughly $160 a year before brushes, filters and bags.
- Homes with limited space near a power outlet
- The 12-in-1 station is large (footprint roughly 24in x 20in) and needs a dedicated mains outlet and clear floor space. It does not need a water line or a drain: the 3.0 L clean and 2.0 L dirty tanks are hand-filled and hand-emptied, which is a trip to the sink every few runs instead.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
eufy Omni S2
- Weekly: Refill the station’s 3.0 L clean water tank and empty the 2.0 L dirty tank; rinse the dirty tank rather than just tipping it.
- Monthly: Rinse the wash tray under the roller and clear hair from the roller brush and brush guard.
- Every 2 months: Replace the roller mop ($26.99), which is eufy’s suggested interval and the largest recurring cost on the machine.
- Every 3-6 months: Replace the filter set and the water tank filter; swap the side brushes when the bristles splay ($21.99 for two pairs).
- As needed: Replace the dust bag when the station reports it full, and the roller brush and brush guard when the brush is worn ($26.99).
- Before any long period unused: Empty both tanks and let the wash tray dry, so standing water does not sit in the station.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
