## What reviewers found

### Dreame L40s Ultra AE

- 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/)

### TP-Link Tapo RV50 Pro Omni

- Expert Reviews: Called navigation impossible to fault and mapping the fastest the reviewer had seen. A 55 minute clean of 24 m2 used 39% of battery. Mopping matched Dreame and Eufy rivals and removed dried ketchup and coffee faster, but it missed a fake pet mess. Awarded Best Buy.

- Blacktubi (9.2/10): A week of use in a 1,200 sq ft apartment with two long haired children: little hair left on the brush, and the clean water tank lasted a full week of daily mopping. Cons were the non refillable detergent and no drain or water inlet option. [Source](https://www.blacktubi.com/review/tapo-rv50-pro-omni/)
