## What reviewers found

### Dreame L50 Ultra

- Vacuum Wars (3.84/5): Measured 90% carpet sand removal, 100% pet hair pickup, 20 of 24 obstacles avoided, a 211 point mopping score versus a 188 average with 0.35 g of water left, and a 42 mm threshold climb; coverage was below average at about 823 sq ft per charge. [Source](https://vacuumwars.com/dreame-l50-ultra-robot-vacuum-review)
- Vacuum Wars (3 month test): After three months of daily use with kids and a heavy shedding dog, mapping and obstacle avoidance held up, but hair formed clumps, the dock and bin clogged about once a week, and the app did not warn of clogs. [Source](https://vacuumwars.com/dreame-l50-ultra-review-3-months)
- RTINGS: In RTINGS' comparison with the L40 Ultra, the L50 Ultra handled pet hair better and had stronger obstacle avoidance and threshold clearance, while the L40 Ultra cleaned hard floors and carpet better. We could not read RTINGS' numeric scores. [Source](https://www.rtings.com/robot-vacuum/tools/compare/dreame-l40-ultra-dreame-l50-ultra/74370/103657)

### Narwal Flow

- Vacuum Wars (3.58 Vacuum Wars stars): Measured 1.88 kPa suction, 83% sand removal, 89% flattened pet hair pickup and 0% hair tangle. Combined mopping score was 268 against a 184 average, obstacle avoidance 18 of 24 and estimated coverage 2,068 sq ft per charge. [Source](https://vacuumwars.com/narwal-flow-review/)
- TechRadar: Called the cleaning superb, especially on carpet, and hot water mopping excellent. Noise was 58 dB in quiet mode and 76 dB at top suction. It pushed a chair, failed to enter a room and once reported 0.0 square meters cleaned. Subscores: Value 4/5, Design 4.5/5, Performance 3.5/5, App 3.5/5. [Source](https://www.techradar.com/home/robot-vacuums/narwal-flow-review)
- Tom's Guide: Pickup was 83% overall on tile and 77% on carpet, with 70% to 75% hair pickup. Noise ranged from 49 to 74 dB depending on floor and power. Faults were a tricky app, random cleaning incidents and so so edge vacuuming. [Source](https://www.tomsguide.com/home/smart-home/narwal-flow-robot-vacuum-and-mop-review)
