## 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/)

### Ecovacs Deebot N30 Omni

- TechHive: Strong suction, accurate multi floor mapping and quiet running. Mop heads are washed with room temperature water, the dock is large and the brush can scatter rice and cereal on hard floors. [Source](https://www.techhive.com/article/2507639/ecovacs-deebot-n30-omni-robot-vacuum-review.html)
- The Gadgeteer: Mapped a 2,004 sq ft home in just under 20 minutes. Brush stayed largely hair free and edge mopping worked, but spot cleaning was undocumented and it struggled with pedestal chair bases and thick rugs.

- Vacuum Wars (3.04 Vacuum Wars stars): Rated overall cleaning, mopping and pet performance above average and obstacle avoidance a weaker area. The page reports scores, not lab percentages. [Source](https://vacuumwars.com/ecovacs-deebot-n30-omni/)
