## 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](https://vacuumwars.com/narwal-flow-2-review/)
- 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.

- 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](https://9to5google.com/2026/06/24/narwal-flow-2-review/)

### 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](https://androidauthority.com/switchbot-s10-review-3465509)
- 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](https://www.thesmarthomehookup.com/products/switchbot-s10/)
