- 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 hard floor robot at half its list price, with a slim body that fits under low furniture. TechGearLab ranked it first overall, but Vacuum Wars found the small bin and hair clogs a pain in a home with a shedding dog. Skip it if you have heavy shedding pets.

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 CurvX
- TechGearLab (85/100): Ranked first of 23 robots. Hard floor and mopping 9.3, carpet 8.4 with about 79% of debris cleaned, but only 52% of pet hair. Avoided 88% of obstacles. Measured 56.3 dB vacuuming. Source
- Vacuum Wars (3.69 Vacuum Wars stars): Long term test in a 750 sq ft home with a dog. Mopping was strong with vacuum then mop runs and nothing wrapped the brush, but the 260 ml bin clogged almost daily and it often tried to climb objects and needed help. Source
- Popular Mechanics: Picked up flour, corn flakes, rice and pet hair on several floors and reached under furniture better than most robots tested. First mapping took about 30 minutes. Source
