ECOVACS DEEBOT T90 PRO Omni vs DEEBOT T30C: Spec-Based Comparison

The ECOVACS DEEBOT T90 PRO Omni claims substantially higher suction (30,000 Pa vs 20,000 Pa) and publishes a lower standard-mode noise level (60 dBA vs 64.4 dB), while the DEEBOT T30C claims the longer quiet-mode runtime (220 minutes vs 140 minutes) and carries a marginally larger robot dustbin (260 ml vs 250 ml). Both carry the same published 12-month limited warranty, and the T30C listed lower on amazon.com when last checked ($699.99 vs $899.99 on August 28, 2026). Both are self-emptying robot vacuums and mops from ECOVACS with hot-water mop washing and auto-empty stations. Three figures need care before you compare them: the headline 350-minute figure for the T90 PRO depends on Perpetual Run adaptive charging rather than a single charge; the two weight figures are not like-for-like, because ECOVACS publishes a robot/station split only for the T90 PRO; and the two noise figures are stated in different conventions (dBA vs dB). We flag each below rather than declaring a winner on them. Every value comes from manufacturer claims captured in our research database; values the manufacturer does not publish are marked unknown.

Key differences at a glance

Full specification comparison

Where the DEEBOT T90 PRO Omni is stronger (per verified specs)

• Higher claimed suction: 30,000 Pa vs 20,000 Pa, with the T90 PRO listing 16 L/s airflow alongside the figure (both are manufacturer claims; suction performance is not independently tested by us).
• Lower published noise level: 60 dBA in standard mode vs 64.4 dB standard sweep. Note the two makers state this differently, so treat the gap as indicative rather than exact.
• Roller mop instead of spinning pads: OZMO Roller 3.0 uses a 10.63 in (27 cm) self-washing roller at up to 200 RPM with pressurized nozzles, versus the dual spinning mop pads on the T30C.
• More capable obstacle avoidance on paper: Mini-ToF navigation with AIVI 3D 4.0 (structured light plus RGB), versus LDS navigation with single-line structured light on the T30C.
• Slimmer robot body: 95 mm tall vs 100.35 mm, which marginally helps under lower furniture.
• Published robot-only weight: 5.3 kg for the robot alone, which is usable for handling and clearance comparisons. The T30C publishes no split.
• Longer dock-assisted mopping session: 350 minutes of standard sweep & mop with Perpetual Run, though this relies on adaptive charging rather than one charge (see caveats below).

Where the DEEBOT T30C is stronger (per verified specs)

• Longer claimed quiet-mode runtime: 220 minutes silent vs 140 minutes silent for the T90 PRO, using the vacuum-only hard-floor figure each maker publishes.
• Marginally larger robot dustbin: 260 ml vs 250 ml.
• Larger dust bag: 3 L vs 2.5 L, both rated to up to 90 days of hands-free emptying.
• Extendable edge mop: TruEdge 2.0 extendable mop with 9 mm auto-lift; the T90 PRO listing describes a fixed roller mop.
• Specified drying temperature: 45 °C hot-air drying is stated explicitly; the T90 PRO listing says hot-air drying without a temperature.
• Lower listed price: $699.99 vs $899.99 on amazon.com when last checked on August 28, 2026.

Not directly comparable

Weight. The T90 PRO publishes the robot and station separately (5.3 kg and 7.9 kg). The T30C publishes a single 11.6 kg net figure with no split between robot and OMNI station on the page we captured. We therefore do not treat 5.3 kg against 11.6 kg as a like-for-like comparison, and we do not declare a lighter model. If robot-only weight matters to you, the T90 PRO figure is the only one of the two that is verifiably robot-only.

Runtime headline figures. The largest T90 PRO number, 350 minutes, is a standard sweep & mop figure achieved with Perpetual Run, meaning the robot returns to the dock to recharge and resumes rather than running for 350 minutes on one charge. The like-for-like single-session comparison is the silent vacuum-only figure: 140 minutes for the T90 PRO vs 220 minutes for the T30C, where the T30C leads.

Noise units. ECOVACS states the T90 PRO figure as 60 dBA and the T30C figure as 64.4 dB. A-weighted sound pressure is the usual convention for both, but because the pages do not use identical wording we report the gap as published rather than as a precise measured difference.

Specifications neither manufacturer publishes (in our verified data)

We could not verify the following from sufficiently reliable sources, so we mark them unknown rather than filling gaps: smart-home platform support details (Alexa, Google Home, Apple Home, Matter) for both models; independent cleaning-performance or suction-at-the-nozzle measurements for both; and current prices — the figures above are dated listing prices, and prices change frequently.

How to read this comparison

This page compares manufacturer-published specifications only. We do not perform hands-on cleaning tests, so we do not declare an overall winner. Where a specification matters to you — for example suction, runtime, dustbin size, or noise — prefer the model whose published claims meet your requirement, and treat unmatched suction figures as marketing claims rather than measured performance.

Sources and verification

All specifications above come from the ECOVACS product pages for the DEEBOT T90 PRO Omni and the DEEBOT T30C (ecovacs.com/us), captured during our research pipeline on August 18, 2026 and stored with per-field provenance in our database. The 12-month warranty figures come from the ECOVACS US Returns & Warranties policy, verified September 7, 2026. Listed prices come from amazon.com product listings last checked on August 28, 2026. Values marked "not published in our data" were not found in the manufacturer documentation we reviewed; they may exist elsewhere.
