ECOVACS Deebot T90 Pro Omni vs Roborock Qrevo S Pro (2026)

Deebot T90 Pro Omni vs Qrevo S Pro head-to-head on verified manufacturer specs only: suction Pa, roller mop vs spinning mops, documented runtime and noise figures, dock capacities, warranty disclosures, with unknowns marked.

The ECOVACS Deebot T90 Pro Omni publishes a higher claimed suction figure (30,000 Pa vs 18,500 Pa), documented battery-runtime figures (up to 140 minutes vacuum-only in silent mode, or 350 minutes sweeping-and-mopping with Perpetual Run), and published noise levels (60 dBA in standard mode), while the Roborock Qrevo S Pro counters with a published 1-year limited warranty (extended option available), a documented combined robot-plus-dock weight (25.6 ± 0.7 kg), and PreciSense LiDAR navigation with structured-light obstacle avoidance. Both are self-emptying flagship robots with all-in-one docks that wash mops with hot water and dry them with warm air. Every value below comes from manufacturer claims captured in our research database and last verified 2026-08-18; values the manufacturers do not publish are marked unknown rather than filled in.

Where the ECOVACS Deebot T90 Pro Omni is stronger (published specs)

Higher claimed suction: 30,000 Pa with a published 16 L/s airflow figure, vs 18,500 Pa. Both are manufacturer marketing claims, not measured performance.
Documented runtime figures: 140 minutes silent / 120 minutes standard vacuum-only on hard floors, and 350 minutes sweep & mop in standard mode with Perpetual Run. The Qrevo S Pro record has no published runtime in our data.
Published noise levels: 60 dBA standard mode, 71–76 dBA dust collection, 60 dBA mop washing — the Qrevo S Pro record publishes none.
Documented dock capacities: 2.5 L dust bag with a claimed up-to-90-day emptying interval, plus published 4 L clean / 2.2 L dirty water tanks.
Roller mop with quantified motion: OZMO Roller 3.0 at up to 200 RPM with pressurized nozzles — a different mop architecture from the Roborock's dual spinning pads.
Published separate weights: 5.3 kg robot and 7.9 kg station.

Where the Roborock Qrevo S Pro is stronger (published specs)

Published warranty: a 1-year limited warranty with an extended option available; the Deebot T90 Pro Omni record has no published warranty terms in our data.
Liftable mops: dual spinning mops that lift — relevant when transitioning between mopping and carpet vacuuming, per the manufacturer's design description.
Documented total system weight: 25.6 ± 0.7 kg including dock, though the robot-only weight is not published separately in our data.
Camera-free obstacle avoidance option: Reactive Tech structured light alongside PreciSense LiDAR, per the manufacturer's specification.

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: battery runtime and noise levels for the Qrevo S Pro; warranty terms for the Deebot T90 Pro Omni; onboard dustbin capacity for the Qrevo S Pro; the robot-only weight for the Qrevo S Pro; smart-home platform support details (Alexa, Google Home, Apple Home, Matter) for both; and current prices. Prices change frequently and are shown only where a dated source exists on the product pages.

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 documented runtime, published noise levels, a stated warranty, or a specific mop architecture — prefer the model whose published claims meet your requirement, and treat unmatched suction figures as marketing claims rather than measured performance.

Where to check current offers

Both models are listed on Amazon US. You can check the current listing for the ECOVACS Deebot T90 Pro Omni or the Roborock Qrevo S Pro. We do not display live prices because prices change frequently and we only show prices where a dated source exists.

Sources and verification

All specifications above come from manufacturer product pages and specification sheets captured during our research pipeline and stored with per-field provenance in our database. Claims for both products were last verified on 2026-08-18. Values marked "not published in our data" were not found in the manufacturer documentation we reviewed; they may exist elsewhere.
