- Vacuum Wars (3.52 Vacuum Wars stars): 85% carpet sand removal, 81% pet hair pickup, 0% hair wrap, 19 of 24 obstacles avoided and about 2,462 sq ft per charge against a 1,015 average. Named Best Value of the Year. [Source](https://vacuumwars.com/dreame-l40s-series-review/)
- Just A Dad Approved (7.9/10): After 90+ days of home testing, liked the AI camera, included TriCut brush and low upkeep, but said corners get less attention without an extending side brush and recommended buying only on deep sale. Its bottom line text names a different model, so treat the score with care. [Source](https://justadadapproved.com/product/dreame-l40s-ultra-ae-robot/)
