Verdict

The Dreame L40s Ultra AE brings much of the X50 Ultras flagship experience to a lower price, combining strong Vormax suction, pet-focused anti-tangle brushes, and a hot-water self-cleaning dock. It is an excellent fit for busy pet households and families who want a largely hands-off robot vacuum and mop with smart mapping and obstacle avoidance.
