- Laser based 3D mapping
- Mopping
- Yes
- Runtime
- 7,000 mAh battery
A well rounded flagship for homes with pets and mostly hard floors. Vacuum Wars measured strong suction, no hair wrap and good obstacle avoidance, and its retest after a firmware update rated the mopping well above average. Tom's Guide was less impressed with edges and corners, and the 3.74 in body will not fit under the lowest furniture.

A strong value for mostly hard floor homes that want a mop washing dock without paying flagship prices. Testers liked the mopping and mapping but saw it eat cables and miss hair on carpet. Skip it if your floors are cluttered or you have long haired pets on carpet.

What reviewers found
Narwal Flow 2
- Vacuum Wars (3.88/5): Lab tests found 84% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap and 20 of 24 obstacles avoided; a retest after a firmware update put mopping well above average, but the studio vacuum and mop run lasted only 38 minutes. Source
- Tom's Guide: Picked up 100% of kitty litter on both floors, 100% of pet hair on hardwood and 80% on carpet, but only 30% and 20% of cereal; reviewer said edges and corners need manual cleaning and it does not live up to its price. Source
- 9to5Google: Cleaned about 1,300 sq ft with back to back vacuum and mop passes without stopping to recharge; reviewer rated it roughly equal to the Roborock Saros 20 but noted the taller body. Source
Roborock Qrevo 2 Pro
- Tom's Guide: Picked up 92.5% of cereal and 60% of hair on hardwood, but only 76.5% of cereal, 51% of flaxseed and 48% of hair on carpet. Mopping cleared soy sauce, mayonnaise and mud in two passes. It bumped furniture with some force. Source
- TechRadar: About 60 dB on carpet and 69 dB peak when emptying. Mopping was excellent on max settings, it avoided a shoe and sock but got caught on a USB cable. Subscores: Value 5/5, Design 4/5, Performance 4.5/5, App 5/5. Source
- Gizmodo (3.5/5): Cleaned a 750 sq ft apartment in just under two hours with over 50% battery left. It swept up micro USB cables and a child's sock, and the test unit needed a fix for a loose part under the brush. Source
