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.

- Mopping
- RevoRoll roller mop
The S10 is for people who want a robot that fills and drains its own water from a nearby sink or laundry line, and testers rated its roller mop highly. Navigation and object detection are weak, it is tall and wide, and setup takes more work than a normal dock. At full price it is expensive, so wait for a sale or look at the newer S20.

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
SwitchBot S10
- Android Authority (AA Recommended): Three weeks of daily vacuuming and mopping three times a week ran hands off when plumbed in. The bot was about an inch too wide for the tester's chair legs and about half an inch too tall for some cabinets. Source
- The Hook Up: Called it the second best mopping performance the reviewer had measured, behind the Eufy S1 Pro, but noted weak object detection and navigation and a mop roller that does not lift high enough for high pile carpet. Source
