Dreame L40 Ultra Gen 2 vs ECOVACS DEEBOT T30C: Spec-Based Comparison

The Dreame L40 Ultra Gen 2 claims the higher suction figure (25,000 Pa vs 20,000 Pa), a slightly longer quiet-mode runtime (up to 231 minutes vs 220 minutes) and carries a published 3-year warranty, while the ECOVACS DEEBOT T30C publishes a noise level the Dreame does not (64.4 dB in standard sweep) and a marginally larger robot dustbin (260 ml vs 250 ml). The Dreame also listed lower on amazon.com when last checked ($499.99 vs $699.99 on August 28, 2026). Both are self-emptying robot vacuums and mops with LDS navigation and structured-light obstacle avoidance. One figure is not directly comparable: Dreame publishes robot and base-station weight separately (4.01 kg robot), while ECOVACS lists a single 11.6 kg net figure with no robot/station split — we flag that below rather than declaring a winner on weight. Every value 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manufacturer claims captured in our research database and last verified on August 18, 2026; values the manufacturers do not publish are marked unknown.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 Dreame L40 Ultra Gen 2 is stronger (per verified specs)

• Higher claimed suction: 25,000 Pa vs 20,000 Pa (both manufacturer claims; suction performance is not independently tested by us).
• Longer claimed quiet-mode runtime: up to 231 minutes in Vacuum Only / Quiet Suction mode vs 220 minutes in silent mode.
• Published warranty: 3-year warranty; no warranty figure is verified for the DEEBOT T30C in our data.
• Separately published robot and station weights: 4.01 kg robot and 8.86 kg base station, which makes the robot-only figure usable for handling and clearance comparisons. ECOVACS publishes only a combined 11.6 kg net figure, so the two are not directly comparable.
• Slimmer robot body: 97 mm tall vs 100.35 mm, which marginally helps under lower furniture.
• Larger dust bag with longer hands-free interval: 3.2 L bag rated to 100 days vs 3 L bag rated to 90 days.
• Lower listed price: $499.99 vs $699.99 on amazon.com when last checked on August 28, 2026.

Where the ECOVACS DEEBOT T30C is stronger (per verified specs)

• Published noise level: 64.4 dB in standard sweep (64.6 dB sweep & mop, 75.2 dB dust collection); Dreame publishes no noise figure in our data.
• Marginally larger robot dustbin: 260 ml vs 250 ml.
• Extendable edge mop: TruEdge 2.0 extendable mop with 9 mm auto-lift; the Dreame listing describes fixed Omni-Scrub spinning mops.
• Specified wash and dry temperatures: 75 °C hot-water mop washing and 45 °C hot-air drying, with a 4 L water tank; the Dreame listing states hot-water washing and hot-air drying without temperatures.
• Smaller station footprint without base: 350 × 294 × 533 mm vs the Dreame base station at 457 × 340 × 590 mm; station dimension conventions differ between makers, so compare carefully.

Not directly comparable

Weight. Dreame publishes the robot and base station separately (4.01 kg and 8.86 kg). ECOVACS publishes a single 11.6 kg net figure with no split between the robot and the OMNI station on the page we captured. We therefore do not treat 4.01 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 Dreame figure is the only one of the two that is verifiably robot-only.

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: Dreame L40 Ultra Gen 2 noise level; ECOVACS DEEBOT T30C warranty; 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 Dreame product page (dreametech.com) and the ECOVACS product page (ecovacs.com/us), 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. Values marked "not published in our data" were not found in the manufacturer documentation we reviewed; they may exist elsewhere.
