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 T50 Ma… | Roomba Plus 678 Combo |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodT50 capable but exceeds typical needs for compact homes; smaller flagship variants offer same Level III mapping at lower cost. | GoodRecharge-and-resume and retained LiDAR mapping comfortably cover a compact single-level home in one scheduled run. |
| 1,500 – 3,000 | GoodMulti-floor mapping retention and consolidated dock suit medium homes with distributed pet-shedding zones. | GoodSystematic LiDAR mapping and recharge-and-resume are built for this range; typical single-level layouts complete in one scheduled run. |
| Over 3,000 | DependsSingle dock limits multi-floor autonomous phasing; larger homes may need dock repositioning or longer scheduled cycles. | DependsIndependent multi-level or large-home coverage testing does not yet exist for this model; recharge-and-resume adds passes rather than eliminating them. |
| Primary floors | ||
| Hard floors | GoodBLAST system optimized for hard-floor loose pet hair. 18,500 Pa handles sealed floors effectively; mop pads improve low-pile particle removal. | GoodThe PowerSpin roller and LiDAR navigation are built around hard-floor vacuum-plus-mop runs. |
| Low / medium pilethey differ | DependsStandard Level III performance on low pile. BLAST advantage minimal on low-pile; main brush handles pile-to-base hair extraction normally. | GoodThe roller auto-lifts on low-pile carpet detection; suction performance on carpet is not independently benchmarked. |
| High pile / shagthey differ | PoorBLAST system targets surface loose hair, not embedded pile extraction. Owner reports show suction loss and main-brush strain on shag and high-pile formats. | DependsNo independent suction or high-pile test results are documented for this model, and rated suction trails the Max-tier sibling. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodStrong vacuum; the mop lifts or detaches when not needed. |
| Light mopping | GoodActive mopping system covers routine floors easily. | GoodActive mopping system covers routine floors easily. |
| Frequent mopping | GoodPressure or rotating mop with self-wash is built for frequent mopping. | GoodPressure or rotating mop with self-wash is built for frequent mopping. |
| You want to… | ||
| Empty bin myself | GoodIntegrated dock reduces hands-on friction (auto-empty, mop-wash automation), but consumables still require weekly pad checks and monthly bag swaps. | GoodThe dock automates roller washing and bin emptying, but a hands-on reader can still top off concentrate and run manual clean cycles. |
| Empty occasionally | GoodDock automation handles dust and mop drying; owner rotates mop pads and swaps dust bags on documented schedule. Balanced autonomy-to-effort. | GoodThe AutoWash dock's self-wash and self-empty cycles handle most routine upkeep between periodic concentrate refills and bag swaps. |
| Set-and-forgetthey differ | PoorConsumable cycles and dock-level maintenance (water tank descaling, valve inspection) require monthly owner engagement. Not maintenance-free. | DependsThe dock automates washing and emptying, but the concentrate reservoir and self-empty bag still need periodic manual refills, so it is not fully hands-off. |
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.

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 T50 Max Pro Omni
BLAST is airflow, not an attachment: a 100 W motor with a 45% larger impeller and a low-resistance duct moving 16.3 L/s. It raises pickup across every surface rather than targeting one kind of debris, and it does nothing about hair that wraps a brush, which is what ZeroTangle 2.0 is there for.
An all-in-one station trades cabinet size for consolidated maintenance: one place to fill, one to empty and one bag to change, in a footprint that has to be found on the floor. It reduces the number of places you attend to, not the number of consumables.
iRobot Roomba Plus 678 Combo
The AutoWash dock hot-washes and heat-dries the roller mop and auto-empties the bin, but that is more moving parts in the dock than a dry-empty-only station, and none of it has independent long-term reliability data yet.
Undercuts the Max 875 Combo by roughly $300 with the same AutoWash dock architecture, but at lower rated suction (30,000 Pa), so the price gap likely tracks a real carpet-cleaning gap, not just branding.
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 T50 Max Pro Omni
- Homes with thresholds above 22 mm
- Ecovacs rates threshold crossing at 22 mm. Raised door sills, thick transition strips and sunken rooms beyond that height leave the robot stranded on one side of the house, and no app setting raises the limit.
- Homes requiring fine-tuned barrier management
- All-in-one dock footprint larger than separate units; dock-only cleaning boundary constraints less flexible than modular setups. Multi-room phasing restricted by single dock home-base.
- Owners seeking weekly maintenance minimization below 30 minutes
- Auto-empty and mop-wash dock reduces hands-on time, but dock-level consumables (dust bag, water tank, mop pads) still require monthly attention. Not maintenance-free.
iRobot Roomba Plus 678 Combo
- Homes with thick or high-pile carpet needing deep-clean suction
- No independent suction or high-pile test results are documented for this model; iRobot's non-flagship Combo units have historically shown reduced pickup on thick carpet.
- Buyers who want the Max tier's higher rated suction
- The Plus 678 is rated at 30,000 Pa; the sibling Max 875 Combo carries a higher published suction figure, so serious carpet cleaning likely favors the pricier model.
- Very large or multi-level homes needing single-pass coverage
- Independent multi-level coverage testing does not yet exist for this model; recharge-and-resume adds passes rather than eliminating them on large floor plans.
- Buyers who need proven multi-year reliability data before purchase
- The model shipped twelve days before this assessment; no independent failure report, teardown, or owner-forum thread yet exists to evaluate the dock's hot-water wash mechanism or the robot itself.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Deebot T50 Max Pro Omni
- Weekly: Mop pad inspection and manual removal if clogged; check the main brush and side brush for wound hair.
- As the station prompts: Refill the clean-water tank, empty the dirty-water tank and top up cleaning solution. The station washes the mops in 167F water and dries them with 113F air on its own.
- Every few months: Replace the 3 L dust bag; Ecovacs sells them in multipacks at a few dollars each.
- Every 3-6 months: Main brush inspection and replacement when worn; filter element swap if clogged (~$20-30).
- In hard-water areas: Fill the clean-water tank with distilled or filtered water to limit scale in the station’s heated water path.
iRobot Roomba Plus 678 Combo
- Weekly: Check the StayClean mopping concentrate reservoir and refill if the dock signals low.
- Monthly: Clear hair wrap from the main brush and roller.
- Every 3-6 months: Replace the self-empty bag.
- Every 3-6 months: Replace the filter (roughly $15-20 for a 3-pack at iRobot’s typical part pricing).
- Every 3-6 months: Replace the side brush.
- As needed: Run the dock’s self-clean cycle and wipe down the roller-wash chamber to prevent buildup.
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 |

| iRobot Roomba Plus 678 Combo | Verified | 7 | 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.
