Roborock Qrevo Curv 2 Flow

What testers say about the Roborock Qrevo Curv 2 Flow

The Roborock Qrevo Curv 2 Flow is the roller-mop version of the Qrevo Curv: its SpiraFlow roller is wetted with fresh water and scraped clean while it mops, extends along edges, presses down with 15 newtons and lifts 15 millimetres on carpet, where a shield slides over it to keep rugs dry. It has 20,000 Pa of suction, a split DuoDivide main brush and two side brushes built against tangles, a lidar turret on top and, according to RTINGS, camera-based obstacle recognition. The station empties the bin into a bag, washes the roller in 75-degree water and dries it with 55-degree air, but has no detergent tank.

As a vacuum it impressed. Tom's Guide measured 89.5 percent overall, with 95 to 97.5 percent of the cereal and kitty litter picked up from hard floors and carpet, and never saw it get lost or stuck. Vacuum Wars measured 87 percent of the sand out of medium-pile carpet, against an average of 76.7 percent, found no hair at all wrapped around the brush and praised its efficient lidar navigation and a bin a fifth larger than the Qrevo CurvX's. RTINGS found it good on hard floors, picking up most everyday debris without scattering it, and quiet enough not to startle pets.

The mop divides the testers. Tom's Guide liked the extending roller once the water output was turned up, but Vacuum Wars measured one of the lowest mopping scores it has recorded, 25 points on dried stains against an average of 112, and suspects the roller uses too little water. Pet hair on carpet is a weak point for RTINGS, and Vacuum Wars measured 77.5 percent against an 81 percent average. The side brushes do not extend, so corners stay less clean, RTINGS saw it bump into things on carpet and not reliably avoid pet waste, and at 119 millimetres it is too tall for low furniture. It is a strong vacuum with a premium station, and for more balanced mopping Vacuum Wars points to the Qrevo CurvX.

Each point sums up, in our words, the review of the test it names, and its link leads to that review. We do not summarise RTINGS or Wirecutter: their lists are linked above.
