ECOVACS DEEBOT T90 PRO OMNI vs Roborock Qrevo Curv 2 Flow

What you'll actually notice

Both products are premium roller-mop robots, but the T90 gives you more hard measurements around that architecture.

The ECOVACS T90 PRO OMNI is about 95mm high, has a verified 15mm mop lift, and separates 24mm single-step from conditional 40mm multi-stage threshold capability. The Roborock Qrevo Curv 2 Flow is 119mm high, uses the SpiraFlow roller and carries a documented TÜV cybersecurity signal, but its exact lift and threshold figures remain unresolved.

That makes T90 easier to validate against a mixed-floor home. Curv 2 Flow is more of an architecture-and-security choice when its taller body and unresolved geometry do not create problems.

The two products may feel similar on a feature sheet because both automate vacuuming, roller mopping and dock care. In the home, the clearer difference is how much uncertainty remains around physical fit.

What changes the choice

Both use roller mopping, so the supporting evidence matters

T90 uses OZMO Roller 3.0. Curv 2 Flow uses SpiraFlow.

That overlap means "roller mop" cannot decide the pair by itself. The useful differences are lift, height, threshold evidence, camera/security architecture and warranty certainty.

T90's 15mm lift is a concrete mixed-floor advantage

T90 has a verified 15mm mop lift with carpet detection.

Curv 2 Flow is carpet-aware, but its exact lift distance is not resolved. If you have thicker carpet or want a quantified wet-mop separation figure, T90 gives you more information to work with.

A 15mm specification still needs to be judged against the carpet you own. It is evidence, not a guarantee for every pile and rug edge.

Height is a meaningful difference

T90 is about 95mm high. Curv 2 Flow is 119mm.

That 24mm gap can decide whether either robot reaches under a sofa or cabinet. Curv is not a low-profile product. If even 95mm is too tall, neither is the right answer; T50 OMNI or Saros 20 belongs on the shortlist instead.

T90 has usable threshold numbers; Curv does not

T90 distinguishes 24mm single-step crossing from 40mm multi-stage geometry.

The higher number must stay conditional. It is not proof of one 40mm vertical step.

Curv's exact threshold values remain unresolved. If a door track is a hard requirement, T90 is easier to validate.

Camera privacy and security assurance are separate

Both products use camera hardware.

T90 includes Video Manager. Curv 2 Flow uses an RGB camera plus structured-light sensing and has a documented TÜV cybersecurity signal.

The TÜV signal is useful security assurance; it does not make Curv camera-free. If the household rejects indoor cameras altogether, neither is the right architecture.

Warranty certainty is currently clearer on Curv

Curv 2 Flow's current Australian record supports a 24-month warranty.

T90's exact Australian warranty duration remains unresolved because the sources conflict. That does not prove Curv is more reliable; it simply means its written warranty period is currently clearer.

Dock automation does not separate them much

Both are high-automation systems with self-emptying, mop washing, drying and water management.

That is useful in both cases but not a reason to pick one over the other. The more important question is whether you need T90's quantified geometry or are comfortable choosing Curv for its roller architecture and security signal despite unresolved dimensions.

The practical choice

T90 is the more straightforward decision when your home is asking measurable questions: Will it fit? How far does the mop lift? What threshold can it cross?

Curv 2 Flow becomes more compelling when those questions are not hard constraints and you specifically value its SpiraFlow architecture and documented cybersecurity signal.

Both docks already automate self-emptying, washing, drying and water management, so dock sophistication is not the useful tie-breaker.

A practical sequence is to measure the furniture opening and threshold first, then decide whether carpet separation is important enough to require a known lift figure. If all three constraints are loose, the choice becomes more about architecture and security preferences.

When to choose ECOVACS T90 PRO OMNI

Choose T90 when:

• 15mm mop lift is useful for mixed floors;
• its 95mm-class body fits where Curv's 119mm body may not;
• 24mm single-step capability suits your transitions;
• you accept camera hardware and Video Manager;
• you can tolerate unresolved warranty duration.

T90 is the better-defined physical package and the easier one to rule in or out using measurements from your home.

When to choose Roborock Qrevo Curv 2 Flow

Choose Curv 2 Flow when:

• SpiraFlow roller mopping is specifically what you want;
• 119mm clearance is comfortably available;
• exact lift and threshold figures are not hard requirements;
• the documented TÜV cybersecurity signal matters;
• a clear 24-month warranty is useful context.

Curv makes more sense when its unresolved geometry is irrelevant to your home rather than something you are hoping will work out.

Choose neither when

Choose neither when you need sub-90mm clearance, high verified single-step mobility, or a camera-free design.

If carpet separation is the dominant issue, also consider a product with automatic mop removal rather than relying only on lift. Those requirements point to a different robot architecture rather than a better choice within this pair.

PIQSY conclusion

T90 PRO OMNI is the easier product to validate for mixed floors because more of its physical geometry is quantified. Qrevo Curv 2 Flow is the more specific architecture/security choice when its taller body and unresolved lift/threshold figures are acceptable.

Start with your floor and furniture measurements, not the brand or suction number.
