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 | Ecovacs Deebot X2 Omni | Roborock S8 Max Ultra… |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | Good180-minute runtime covers single-session cleaning for most homes under 1500 sq ft without mid-run docking. | GoodRoborock lists up to 180 minutes of runtime, and the dock handles water without refills. |
| 1,500 – 3,000they differ | Depends200ml mop water tank requires refilling mid-session on homes 1500-2500 sq ft; larger homes need dock return. | GoodIndependent lab testing saw nearly perfect coverage, and plumbing removes tank refills on long runs. |
| Over 3,000they differ | Poor180-minute runtime and mop water capacity insufficient for single-session coverage above 3000 sq ft. | DependsIndependent lab testing rated its navigation efficiency about average, and no large-home test was found. |
| Primary floors | ||
| Hard floors | GoodVacuum and mop both optimized for hard floors. LiDAR navigation and mop water distribution work reliably. | GoodIndependent lab testing found near-perfect debris pickup and strong stain removal on hard floors. |
| Low / medium pile | GoodStandard carpet pile handled well. LiDAR and carpet-detection mop lift perform as documented. | GoodIndependent lab testing found carpet pickup nearly perfect, and pads lift 20 mm to stay dry. |
| High pile / shag | DependsMop pad lift occasionally misses high-pile and shag carpets; owner reports recommend no-mop zones for these areas. | DependsIndependent lab testing rated its airflow and carpet deep clean below average, and no high-pile test was found. |

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.

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.
Ecovacs Deebot X2 Omni
The OMNI Station washes and dries the mop pads and empties the bin after every session, but its own 4 L clean and 3.5 L dirty tanks are filled and emptied by hand.
AIVI 3D 2.0 pairs an RGBD sensor with the onboard camera for obstacle recognition, which puts a camera and a microphone in every room the robot enters, with no local-only mode available.
Roborock S8 Max Ultra with Refill & Drainage System
The dock takes over every water chore, and in exchange it needs plumbing work before its first run.
Structured-light obstacle avoidance keeps a camera out of the home; independent lab testing found the camera model avoided obstacles better.
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.
Ecovacs Deebot X2 Omni
- Homes with frequent layout changes
- LiDAR mapping assumes stable furniture placement. Frequent rearrangements require manual map retraining, creating maintenance overhead.
- High-traffic homes with excessive obstacles
- Obstacle recognition covers common household items but can miss glass, clear barriers and loose fabric. Homes with many loose cords, mats, or furniture still need a clearing pass before a run.
- Homes with large carpeted areas
- Mop pad lift works reliably but is not guaranteed on all carpet types. Owners with mixed thick carpets report occasional missed lifts.
- Renters or temporary placements
- The station needs a permanent level spot with mains power and is not quick to relocate. It requires no plumbing, but it is a large appliance to move between homes.
- Owners unwilling to run a camera and microphone on a cloud account
- The robot carries a camera, a microphone and the onboard YIKO assistant, and there is no local-only mode. A Bluetooth flaw disclosed in 2024 allowed remote takeover of X2 units including camera and microphone access, before Ecovacs patched it in November 2024.
Roborock S8 Max Ultra with Refill & Drainage System
- Renters or homes without a nearby water line and drain
- The dock must connect to a water supply and a drain within Roborock's stated distances, which many layouts cannot provide.
- Buyers who want a camera for obstacle recognition
- It uses structured light rather than a camera, and independent lab testing found the camera-equipped S8 MaxV Ultra avoided obstacles better.
- Dock sites behind a threshold over 2 cm
- Roborock's installation guidance warns against thresholds, tracks or steps above 2 cm between the dock and the cleaning area.
- Buyers who need an independent test of the plumbed version
- Independent lab testing covered the standard-dock S8 Max Ultra and noted the refill and drainage variant had not been reviewed.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Deebot X2 Omni
- After every use: None. The station empties the robot’s 0.42 L bin and washes and dries the mop pads.
- Weekly: Refill the 4 L clean water tank and empty the 3.5 L dirty tank as the app prompts; check the side brush for tangles.
- Monthly: Rinse the station’s wash tray and nozzles with water; inspect for hardness buildup.
- Every 2-3 months: Replace the 3 L dust bag when the app reports it full.
- Every 3-6 months: Replace the station water filters depending on local water hardness, approximately $30 per set.
- Every 6-12 months: Replace main brush and side brush, approximately $40-60 for a genuine set.
- Annually: Inspect the station’s rubber seals for wear.
Roborock S8 Max Ultra with Refill & Drainage System
- As needed: Replace the 2.5 L dock dust bag; Roborock sells 6-packs.
- Every 3-6 months: Refill the 580 ml detergent tank, which Roborock says lasts over three months.
- As needed: Check the water inlet and drain connections for leaks, per Roborock’s installation notes.
- As needed: Replace mop cloths and edge mop cloths; Roborock’s US store sells both.
- As needed: Replace the washable filters and main brush pack, which Roborock’s US store sells for the S8 Max Ultra.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| Ecovacs Deebot X2 Omni | Verified | 11 | Dec 2025 |
| Roborock S8 Max Ultra with Refill & Drainage System | Provisional | 6 | Sep 2026 |
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.
