$1,049.99as of Jul 6

The Narwal Flow 2 stands out as one of the most advanced robot vacuums tested, featuring a Visual Language Model with dual HD cameras and a 10-TOPS AI processor for unlimited object recognition. Vacuum Wars praised its strong obstacle avoidance, 31,000 Pa suction, and premium dock automation, though mopping performance fell short in controlled tests. YouTube reviewers highlighted its unique track mop system and effective oatmeal cleaning, while noting some early app connectivity issues. Best for tech-savvy early adopters seeking AI-driven cleaning, but those prioritizing stain removal should consider alternatives.

Roborock QRevo Curv 2 Flow
Ranked #9 in Best Robot Vacuums
Roborock QRevo Curv 2 Flow
$999.99as of Jul 6

The Roborock Qrevo Curv 2 Flow delivers strong vacuuming performance with 20,000 Pa suction and a 325 ml dustbin, but disappoints in mopping capabilities, particularly on dried stains. RTINGS.com noted its SpiraFlow roller mop handles wet spills well but falls short in real-world testing. YouTube reviewer Jamie Andrews confirmed excellent carpet pickup (96% recovery) but found the mop system only partially effective on baked-on stains, requiring multiple passes. The device features solid navigation and app functionality but lags behind its predecessor in obstacle avoidance. This model is best for users prioritizing vacuuming over mopping, with pet owners benefiting from its live monitoring features.

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

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.
