## What reviewers found

### Dreame L40 Ultra Gen 2

- Vacuum Wars (3.11 Vacuum Wars stars): Dried stain score 144 (108 average), 90% carpet sand removal, but 69% pet hair pickup, 67% hair wrap and only 2 of 24 obstacles avoided. Estimated about 1,290 sq ft per charge. [Source](https://vacuumwars.com/dreame-l40-ultra-gen-2-review/)
- Vacuum Chef: Measured 11.5 CFM airflow, 90% coffee, 60% sand and 98% cat litter pickup, 73 dB at max and a 30% obstacle avoidance score against a 66% average. Called it a rebalancing rather than an upgrade. [Source](https://vacuumchef.com/?p=12466)

### eufy Omni E25

- Vacuum Wars (3.58 Vacuum Wars stars): Removed 88% of embedded sand from carpet against a 75% average and 93% of flattened pet hair with 0% long hair wrap. Avoided 21 of 24 obstacles and scored 218 on mopping against a 188 average. Ranked #7 on its Top 20 list. [Source](https://vacuumwars.com/eufy-e25-omni-robot-vacuum-review/)
- TechRadar: Fine dust like flour and crumbs was cleared in one pass on hard floors, but rice was sometimes scattered and high pile carpet kept a few grains. Edge cleaning was weak. Dried ketchup survived automatic mode and took a few passes on the highest mop setting. A 700 sq ft mixed floor clean took about 1 hr 30 min with dock trips. [Source](https://www.techradar.com/home/robot-vacuums/eufy-e25-omni-review)
- Expert Reviews (UK): Picked up close to 100% of rice and dog hair and did well with flour on hard floors, but only about 65% of flour on carpet. Cleaned 20 square meters in 23 min using 30% battery, which the reviewer projects to about 67 square meters per charge. The roller mop removed most of a dried stain. One drive wheel got stuck in a narrow gap. [Source](https://www.expertreviews.co.uk/home-garden/vacuums-cleaning/eufy-omni-e25-review)
