A capable mopper with a full dock for about $500 to $570, but a step back from the original L40 Ultra in obstacle avoidance. Vacuum Wars saw it avoid only 2 of 24 objects and wrap 67% of long hair. Pick it only for tidy homes without long hair; Vacuum Wars itself points pet owners to the L40s Ultra.

One of the best values in a roller mop robot, with excellent pet hair pickup, no long hair tangles and fast LiDAR navigation in Vacuum Wars testing. Measured suction and airflow were below average, the dustbin is small and the roller does not reach right up to walls. Early units had a dirty water tank leak that eufy fixed with replacement tanks.

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
- 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
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
- 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
- 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
