Narwal Flow 2 comes out ahead by a narrow margin (4.2 vs 4.5). The gap is mostly about early adopters seeking AI-powered cleaning — read the strengths below before deciding.

Ranked #6 in Best Robot Vacuums

Ecovacs T80S

4.2

5 sources1 derived$649.99as of Aug 1

The Ecovacs T80 Omni, also sold as the T80S, takes flagship OZMO mopping technology down to a mid-tier price. Reviewers praised the powerful suction, the pet hair removal, and a navigation system that combines LiDAR with 3D structured light. Mopping scored well above average, particularly in dried-stain tests. The recurring complaint was occasional stalling during reviewers' testing. It fits buyers who want premium features without the highest price tag; anyone on a tighter budget should look at lower-tier models.

Strengths

— OZMO roller-mop system with 200 RPM spinning and real-time rinsing for streak-free mopping
— 18,000 Pa brushless motor with ZeroTangle 3.0 brushes for strong pet hair and debris pickup
— AIVI 3D 3.0 with LiDAR navigation recognizing over 100 objects for intelligent obstacle avoidance

Watch-outs

— Occasional test-area stalls noted in performance evaluation
— Price is still several hundred dollars above entry-level models

Higher ratedRanked #2 in Best Robot Vacuums

Narwal Flow 2

4.5

4 sources$1,499.99as of Aug 1

The Narwal Flow 2 is a top-of-the-line robot vacuum: embedded lidar, dual cameras and a rolling track mop that washes itself while it works, all fed by a dock that empties the bin and dries the mop with heated air. Bob Vila's month with it returned full marks and Basic Tutorials scored it 97 out of 100, though How-To Geek's 7 out of 10 is a cooler read. At $1,499.99 it is priced for people who want the whole system automated, and early owners report mapping and app problems that a machine this expensive should not have.

Strengths

— Embedded lidar plus dual HD cameras and on-device object recognition
— 31,000 Pa suction with anti-tangle brush geometry
— Rolling track mop rinses and scrapes itself while it cleans

Watch-outs

— Onboard bin holds only 300 ml, so the robot depends on the dock
— Mapping and app reliability problems reported by early owners
— Multi-floor navigation is noticeably less efficient than single-floor

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Ecovacs T80S

The Ecovacs T80S offers a balance of suction and navigation with its LiDAR system, outperforming the Lefant M5 Max and Dreame D30 Ultra in these areas. However, it's less effective in mopping than the Mova V50 and lacks the AI features of the Narwal Flow 2, making it a mid-tier option for users seeking affordable premium features.

Narwal Flow 2

The Narwal Flow 2 leads in AI-driven navigation with its Visual Language Model and dual HD cameras, surpassing the Dreame X60 Max Ultra and Roborock Saros 20 in object recognition. However, it underperforms in mopping effectiveness compared to the Ecovacs T90 Pro Omni and Mova V50, and its app reliability issues make it less ideal than the Roborock Q10 S5+ for consistent performance.
