ECOVACS T90 Pro Omni vs Roborock Qrevo Curv 2 Flow: Which Roller Mop Fits Better?

The decision

Both robots are built around a continuously refreshed roller-mop workflow, so the choice should turn on the constraints around that architecture.

Choose the ECOVACS T90 Pro OMNI when you need the more quantified physical package: about 95mm height, 15mm mop lift, 24mm single-step crossing and a conditional 40mm multi-stage figure.

Choose the Roborock Qrevo Curv 2 Flow when its SpiraFlow roller architecture and documented TÜV cybersecurity signal are specifically valuable and its 119mm body is acceptable. PIQSY does not currently have an exact Curv mop-lift or threshold figure, so it should not win those dimensions by inference.

What changes the choice

Both are roller-mop robots

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

That makes this a legitimate architecture comparison, but it does not prove either robot mops better in every home. The presence of a roller establishes the cleaning system; comparative performance requires comparable exact-model testing.

PIQSY therefore starts with what is verified around the roller rather than declaring a roller winner from marketing language.

T90 gives you a verified 15mm lift; Curv does not

T90's current canonical record states a 15mm mop lift with carpet detection.

Curv 2 Flow is carpet-aware, but its exact lift distance remains unresolved in the canonical record.

For a mixed-floor buyer who needs a quantified separation figure, that makes T90 easier to evaluate. It does not guarantee every thick carpet will remain untouched; the lift still has to be judged against the actual floor.

The height difference is large

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

That 24mm difference can be decisive under sofas, beds or cabinets. Neither should be called a low-profile specialist, but Curv's taller body is materially more restrictive.

If the opening is genuinely low, move beyond this pair: T50 OMNI at 81mm or Saros 20 at 79.8mm are stronger geometry-first candidates.

T90 has threshold numbers; Curv remains unconfirmed

T90's canonical evidence distinguishes 24mm single-step crossing from a conditional 40mm multi-stage figure.

The 40mm figure is not a generic 40mm vertical-step claim.

Curv 2 Flow's exact threshold figures remain unresolved. PIQSY does not copy threshold or chassis claims from another Qrevo model.

If a door track is a hard constraint, T90 gives you usable exact-model evidence. For materially higher single steps, look to a dedicated threshold specialist instead.

Privacy and security are two different questions

Both products have camera hardware.

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

If the shopper wants no indoor camera, neither gets a camera-free advantage. If the shopper accepts camera hardware but values documented security assurance, Curv's TÜV signal is relevant.

Security certification does not erase camera presence.

Warranty certainty currently favours Curv

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

T90's Australian warranty duration remains unresolved because the governed sources conflict. PIQSY therefore keeps the exact duration out of recommendation logic rather than selecting the more favourable source.

That does not prove Curv is more reliable. It means Curv's written warranty duration is currently clearer.

Dock automation does not separate them much

Both are full-service systems with self-emptying, mop washing, drying, water refill and detergent automation.

The dock is therefore not the main reason to choose between them. The differentiators are physical geometry, quantified carpet separation, threshold evidence, camera/security architecture and warranty certainty.

PIQSY conclusion

Choose T90 Pro OMNI if:

• the 15mm verified mop lift helps with your mixed floors;
• its ~95mm body fits where Curv's 119mm body may not;
• you need a verified 24mm single-step figure;
• camera and Video Manager are acceptable;
• you can tolerate unresolved written warranty duration.

Choose Qrevo Curv 2 Flow if:

• you specifically want the SpiraFlow roller architecture;
• its 119mm body fits comfortably;
• exact mop-lift and threshold numbers are not hard requirements;
• the documented TÜV security signal matters to you;
• its clearer 24-month warranty is useful context.

Choose neither when sub-90mm clearance, high single thresholds or camera avoidance is the hard requirement.
