## What reviewers found

### Dreame L40s Ultra CE

- Vacuum Wars (3.10 Vacuum Wars stars): 89% carpet sand removal, 68% pet hair pickup, 0% hair wrap, 8 of 24 obstacles avoided, about 1,922 sq ft per charge and 2.20 g of water left behind, the most of the three L40s models. Not in its Top 20. [Source](https://vacuumwars.com/dreame-l40s-series-review/)
- The Smart Home Hookup: Ranked it with the Mova P50 Ultra at the top for vacuuming among robots from the last three years and tied for first in mopping with the Narwal Flow. Noted the detergent dispenser is sold separately; listed $469.99 MSRP. [Source](https://www.thesmarthomehookup.com/?p=10269)

### Eureka E10s

- AppleInsider: Solid daily vacuuming, especially on carpets in turbo mode, but the 200 ml tank and lack of a low water alert made mopping underwhelming; turbo runtime was about half the advertised 180 minutes. Marked as sponsored content. [Source](https://appleinsider.com/articles/23/11/15/eureka-e10s-review-an-ideal-solution-for-everyday-cleaning)
- TechRadar: Good mid range robot for daily cleaning; mapping took wrong turns at first, mopping handled fresh spills but not stains, and the self empty path sometimes clogged. Runtime at max suction was just over an hour. TechRadar gave a Performance 3.5/5 subscore but no overall rating. [Source](https://www.techradar.com/home/robot-vacuums/eureka-e10s-robot-vacuum)
- Vacuum Wars (1.87/5): Strong real world cleaning and better than average mopping for its price, but below average airflow and suction bench results, slow navigation and a buggy app where no mop zones did not work. [Source](https://vacuumwars.com/eureka-e10s-review/)
