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

Ranked #10 in Best Robot Vacuums

4 sources1 derived$999.99as of Aug 1

Vacuuming is where the Roborock Qrevo Curv 2 Flow earns its keep, with 20,000 Pa suction and a 325 ml dustbin. Mopping is the letdown, especially on dried stains. RTINGS.com found the SpiraFlow roller mop handles wet spills well but falls short in reviewers' real-world testing, and YouTube reviewer Jamie Andrews confirmed excellent carpet pickup at 96% recovery while getting only partial results on baked-on stains, which needed multiple passes. Navigation and app functionality are solid, though obstacle avoidance is a step back from its predecessor. Pick it if vacuuming matters more than mopping; pet owners also get live monitoring.

Strengths
  • Strong vacuum performance with 20,000 Pa suction power
  • Larger 325 ml dustbin capacity compared to previous model
  • Effective SpiraFlow roller mop system for wet spills
Watch-outs
  • Below-average mopping performance on dried stains
  • Poor obstacle avoidance compared to CurvX model
  • Unimpressive airflow and suction in real-world testing

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

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.

Roborock QRevo Curv 2 Flow

The Roborock QRevo Curv 2 Flow provides strong vacuuming and a larger dustbin compared to the Dreame D30 Ultra, but it underperforms in mopping compared to the Ecovacs T90 Pro Omni and Mova V50. It also lacks the advanced navigation of the Narwal Flow 2 and the superior carpet cleaning of the Roborock Q10 S5+, making it best for users prioritizing vacuuming over mopping.
