A strong value pick for carpet and pet hair, with the highest sealed suction in Vacuum Wars' comparison and perfect hair results. It trails the T90 Pro Omni on navigation, mopping and thresholds, so at current prices the T90 is the better buy unless its deal ends. Skip it if your home has raised thresholds.

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
- 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
Ecovacs Deebot T80S Omni
- Vacuum Wars (3.92/5): Measured 2.44 kPa suction, 91% carpet sand removal, 100% pet hair pickup, 0% hair wrap, 21 of 24 obstacles avoided and a 30.5 combined mopping score; navigation was below average at 0.62 sq m per minute and it cleared 19 mm. Source
- CyberShack (4/5): Strong pickup and close wall mopping, but it drove into a water bowl, could not reliably climb 3 cm bathroom thresholds and sometimes spilled debris while emptying. Source
