Roborock Qrevo Curv vs Narwal Flow

The Narwal Flow struggles with fundamental cleaning performance that makes it impossible to recommend over the Roborock Qrevo Curv. While the Flow has better obstacle avoidance capabilities, this doesn't compensate for its poor debris pickup on hard floors and carpets, which stems from severe navigation and pathing problems, causing it to miss entire sections of your home. The Qrevo delivers excellent hard floor cleaning and adequate carpet performance. It also doesn't have the Flow's crippling software limitation that locks you out of settings on secondary maps. This makes the Qrevo far more versatile for multilevel homes where you need different cleaning configurations on different floors.
