ECOVACS DEEBOT T90 PRO Omni vs Dreame L40s Ultra CE: Spec-Based Comparison

The ECOVACS DEEBOT T90 PRO Omni publishes a higher claimed suction (30,000 Pa vs 13,000 Pa), a published standard-mode noise level (60 dBA), and a slimmer robot body (95 mm vs 104 mm tall). The Dreame L40s Ultra CE counters with a longer claimed maximum runtime (up to 260 minutes vs 140 minutes), a larger robot dustbin (320 ml vs 250 ml), a lighter robot (3.9 kg vs 5.3 kg), a 3-year warranty, and a lower listed price ($469.99 vs $899.99 on amazon.com when last checked on August 28, 2026). Both are self-emptying robot vacuums with 3D obstacle avoidance. Every value below comes from manufacturer claims captured in our research database and last verified on August 18, 2026; values the manufacturers do not publish are marked unknown.

Key differences at a glance

Full specification comparison

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

• Higher claimed suction: 30,000 Pa vs 13,000 Pa (both manufacturer claims; suction performance is not independently tested by us).
• Published noise level: 60 dBA in standard mode, plus dust-collection (71/76 dBA) and mop-washing (60 dBA) figures; Dreame publishes no noise figure in our data.
• Slimmer robot body: 95 mm tall vs 104 mm, which helps under lower furniture.
• Smaller published station footprint without base: 338 × 281 × 500 mm vs the L40s Ultra CE base station at 340 × 457 × 590 mm; station dimension conventions differ between makers, so compare carefully.

Where the Dreame L40s Ultra CE is stronger (per verified specs)

• Longer claimed maximum runtime: up to 260 minutes in Vacuuming Mode (quiet suction) vs 140 minutes silent mode for the T90 PRO Omni.
• Larger robot dustbin: 320 ml vs 250 ml.
• Lighter robot: 3.9 kg vs 5.3 kg.

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: ECOVACS DEEBOT T90 PRO Omni mop system details, dock function list, and warranty; Dreame L40s Ultra CE noise level; smart-home platform support details (Alexa, Google Home, Apple Home, Matter) 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 runtime, dustbin size, or warranty length — 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 page (ecovacs.com/us) and the Dreame product page (dreametech.com), captured during our research pipeline on August 18, 2026 and stored with per-field provenance in our database. Listed prices come from amazon.com product listings last checked on August 28, 2026.
