Dreame Technology has launched the L40s Series, a lineup of three robot vacuums aimed at bringing advanced cleaning capabilities to every household. The range consists of the flagship L40s Ultra, the balanced L40s Ultra AE, and the accessible L40s Ultra CE. While they share Dreame’s signature navigation, suction efficiency, and smart home integration, each model is tailored to different needs and budgets. Here’s how they stack up.
Design and Navigation
All three models feature Pathfinder smart navigation and 3DAdapt obstacle avoidance, allowing them to map rooms, plan efficient cleaning routes, and dodge everyday clutter. The L40s Ultra stands out with its EasyLeap System, capable of tackling 40mm double-layer steps with ease. The L40s Ultra AE offers the same obstacle handling minus the auxiliary wheel enhancements, while the L40s Ultra CE focuses on streamlined navigation optimized for apartments and smaller spaces.
Cleaning Power and Floor Care
The L40s Ultra and Ultra AE share the same flagship 19,000Pa Vormax suction system, delivering deep cleaning across carpets and hard floors. The Ultra pairs this with the HyperStream Detangling DuoBrush for advanced hair management, while the Ultra AE uses a Liftable Rubber Brush with TriCut Brush 3.0 for easier maintenance in family homes. The Ultra CE uses a 13,000Pa Vormax system but adds ultrasonic carpet detection for targeted suction boosts. All models integrate mopping, but the Ultra leads with MopExtend RoboSwing and four-temperature mop washing, the Ultra AE offers 75°C hot water cleaning, and the CE uses DuoScrub rotary scrubbing for efficient everyday floor care.
Maintenance and Automation
Dreame has designed the L40s range for minimal manual intervention. The L40s Ultra features an 8-in-1 PowerDock with AceClean DryBoard, automating mop washing, drying, dust emptying (up to 100 days), and faster charging. The Ultra AE includes Self-Cleaning Washboard 2.0 for its base station, which reduces upkeep while keeping the price approachable. The Ultra CE delivers hands-free maintenance via an all-in-one base station with a 3.2L dust bag, suitable for up to 100 days of debris storage but without the extra mop drying hardware found in the Ultra.
Smart Features and Everyday Use
Every model in the series supports multi-floor mapping, Alexa and Google Assistant integration, and app-based zone customization. The L40s Ultra is geared towards tech enthusiasts, offering the most automation and obstacle handling. The Ultra AE targets busy families with hygienic mop cleaning and reliable hair-tangle prevention. The Ultra CE is perfect for first-time robot vacuum owners or renters seeking strong suction and mopping in a cost-efficient package. No matter the choice, Dreame ensures professional-grade performance without locking features behind the highest price point.
Conclusion
The Dreame L40s Series proves that premium cleaning technology can be accessible across budgets. From the feature-rich L40s Ultra to the balanced Ultra AE and the entry-level Ultra CE, each model offers a distinct mix of power, automation, and value. All are available now in the U.S. with special launch discounts until August 31, making it an excellent time to join the Dreame ecosystem and upgrade your home cleaning game.
