DREAME L40s Ultra AE Robot Vacuum and Mop
Verdict
The Dreame L40s Ultra AE brings many of the X50 Ultra’s flagship capabilities to a more attainable price, with strong suction, advanced Pathfinder navigation, robust obstacle avoidance, and a highly automated dock. It is especially appealing for pet and family homes thanks to its anti-tangle TriCut brush and pet-focused design, though it still sits in the premium price tier even when discounted.
