Roomba Max 775 vs eufy C28: Which Mop and Dock Workflow Fits?

Choose the Roomba Max 775 if a selectable mop-only run and its published carpet-detection roller cover matter. For dock care, both systems automate several steps; eufy lists wastewater collection and gives a solution-dispensing ratio, while iRobot describes StayClean mixing and lists its own recurring care tasks. The cited pages do not establish which is easier, cheaper, or lower-maintenance.

The buying question

Which of these two exact US models better fits a home that uses both rugs and hard floors and wants to understand the dock's ongoing care steps?

The Roomba Max 775 page documents selectable mop modes and an automatic roller cover when carpet is detected; C28 support documents a combined vacuum-and-mop workflow plus carpet suction settings. For dock care, both manufacturers describe automated emptying, roller cleaning/drying, and solution refill or dispensing. Their instructions then list different owner-care details, without comparable maintenance time, frequency, or ownership-cost evidence.

Quick verdict

Choose eufy Robot Vacuum Omni C28 (T211A110) if

  • You prefer the C28’s listed station functions and its support-documented solution-dispenser instructions; compare the current care guide for your exact unit before treating either workflow as less work.

When to skip: You require a robot-and-dock combination with no owner care tasks; both manufacturers document cleaning or upkeep steps for these models.
When the recommendation changes
  • If a separate mop-only pass and the Max 775 page’s carpet-detection roller cover are not important, that feature-fit reason matters less; C28’s specific rug mop-protection behavior remains unverified in the cited support pages.
  • If dock upkeep is decisive, neither model has a supported workload advantage here: both automate several of the same steps, and the cited pages do not provide matched care intervals, time, or replacement costs.

The differences that matter

Mop Surface Transition Workflow

iRobot Roomba Max 775 Combo Robot + AutoWash Dock (X285020)

Four listed modes include mop-only; the X285020 page says the roller lifts and is covered when rugs or carpets are detected, switching to vacuum-only.[1]

eufy Robot Vacuum Omni C28 (T211A110)

C28 support says there is no mopping-only mode; it recommends Vacuum-Only before the first mopping session and highest suction with BoostIQ for carpets.[3, 4, 5]

What this changes: A buyer wanting a separate mop-only run and a published automatic rug-cover workflow has a direct feature-fit reason to choose the Max 775; the C28's cited carpet instructions address suction settings, not the mop-protection mechanism.[1, 3, 4, 5]

The better fit depends on your priorities

Dock Care And Recurring Consumables

iRobot Roomba Max 775 Combo Robot + AutoWash Dock (X285020)

The X285020 AutoWash FAQ says the dock auto-empties debris, washes and dries the roller, mixes StayClean concentrate with clean water, and refills the robot. iRobot also lists bin wiping, tank rinsing, contact/brush cleaning, and filter replacement every 3–6 months.[1]

eufy Robot Vacuum Omni C28 (T211A110)

The eufy US C28 listing with SKU T211A110 lists dust emptying, mop washing, water refill, hot-air drying, and wastewater collection. C28 support says to enable the automatic solution dispenser and mix eufy solution at 1:200; it also directs regular roller-mop and dirty-water-tank cleaning.[2, 4]

What this changes: Several automated steps overlap, including dust emptying, roller cleaning/drying, and solution refill or dispensing; the listed functions do not show that one dock leaves less work. The cited instructions give different care details but no matched maintenance frequency, owner time, or parts cost, so use them to check which exact routine and supplies fit your home rather than treating either as a dock-care winner.[1, 2, 4]

The better fit depends on your priorities

A buyer comparing what each dock automates and which model-specific solution and owner-care instructions to follow

The better fit depends on your priorities

Both sources describe several overlapping automated steps. The C28 instructions give a 1:200 eufy-solution ratio and roller/tank cleaning guidance; iRobot lists its own bin, tank, contact, brush, and filter care. The cited pages do not establish lower owner effort, frequency, or cost for either model.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If one option is currently priced higher, weigh it against the specific mode and documented station routine you will use. The cited care information does not establish a lower-maintenance or lower-cost premium.

There is not enough validated multi-month price history for a buy-now or wait recommendation.

Limitations

  • The C28 carpet support page gives suction-setting advice; it does not establish how the mop is protected on rugs or verify behavior for a particular carpet pile.
  • The dock pages describe several overlapping automatic steps, but do not give matched maintenance time or frequency. They also do not provide comparable replacement intervals and parts pricing for both exact packages, so no annual or three-year consumables total is estimated.
  • No comparable controlled cleaning test or long-term reliability study was used. Published features and support steps are not measured cleaning results or reliability findings.
  • Use the care instructions supplied for your exact unit and current app version when planning recurring maintenance.

Questions shoppers ask

Can the C28 run a mop-only pass?

eufy support says the Omni C28 does not have a mopping-only mode. Its instructions recommend using Vacuum-Only mode before the first mopping session.

What do the docks automate, and what care do the makers still list?

Both manufacturers describe automatic dust emptying, roller washing/drying, and solution refill or dispensing. iRobot says the X285020 dock mixes StayClean concentrate with clean water and lists wiping the bin, rinsing dock tanks, cleaning charging contacts and brushes, and changing the filter every three to six months. eufy support says to enable its automatic solution dispenser and use a 1:200 mix with eufy solution; it also says to clean the C28 roller mop and dirty-water tank regularly. The cited instructions do not establish which routine takes less time or costs less.

Can these sources establish which robot cleans rugs better or costs less to maintain?

No. They describe manufacturer-listed modes and care guidance, not a controlled side-by-side cleaning test or matched parts replacement costs, intervals, or maintenance time. C28 mop-protection behavior on a specific rug also remains unverified in the cited support pages.

Methodology and sources

The model numbers are X285020 and T211A110. The comparison focuses on selectable mop modes, published carpet-transition guidance, overlapping dock automation, and the remaining model-specific care directions; it does not treat station feature lists as proof of lower owner effort or translate advertised specifications into cleaning-performance claims.

Research assistance was used to locate and organize official product and support information; no unit was tested or handled.
