Floor cleaning is one of those tasks that never quite feels effortless. Spilled coffee in the kitchen, crumbs under the sofa, pet hair in every corner – you get the picture. But Dreame’s L40s robot vacuum series aims to make that daily slog a little less of a chore. Across three models named the Ultra, Ultra AE and Ultra CE, the brand combines thoughtful engineering with practical design, offering all the features you’d expect from a high-end smart home set-up, but at various levels to suit different lifestyles. Kids, dogs, you name it.
The L40s Ultra sits at the top of the range, pairing its powerful 19,000Pa Vormax™ suction with the EasyLeap™ mobility system and HyperStream™ Detangling DuoBrush. It’s the kind of machine that could almost make you forget about those long-standing dust bunnies lurking behind the couch. The L40s Ultra AE holds onto the same super suction while honing in on the nuances of family life. This means teenage hair tangles are minimized with the TriCut Brush 3.0, while RoboSwing mopping and hot-water cleaning tackle everything from sticky snack spills to muddy footprints. Lastly, the L40s Ultra CE proves that hands-free maintenance doesn’t have to break the bank, offering 13,000Pa suction, DuoScrub™ mops and an all-in-one PowerDock™ that can run for up to 100 days without intervention.
Smart navigation, obstacle avoidance and adaptive brushes allow each model to handle diverse floors, from low-pile carpets to hardwood and tile, while keeping little fingers and paws (and the messes that come with them) in mind. Below, we explore how these three machines approach home cleaning differently, plus what makes each a contender for modern households.
L40s Ultra: The pinnacle of precision cleaning
At the forefront of Dreame’s lineup, the L40s Ultra is designed for homes that demand top-tier performance, with 19,000Pa Vormax™ suction (mentioned above) to ensure deep cleaning across everything from fluffy rugs to smooth vinyl. The EasyLeap™ system allows the vacuum to cross thresholds up to 1.57 inches, making it adept at navigating multi-level homes, while the HyperStream™ Detangling DuoBrush tames stray strands. And, for those ever-neglected areas, its Dual Flex Arm Technology enhances edge and corner cleaning. Additionally, the 8-in-1 PowerDock™ with its AceClean DryBoard offers automated maintenance, including self-emptying and mop washing, reducing manual intervention when other tasks take precedence.

L40s Ultra AE: Tailored for family dynamics

Optimized for bustling homes, the L40s Ultra AE maintains the powerful 19,000Pa suction of its predecessor but introduces features that cater to hectic household needs. The TriCut Brush 3.0 makes sure that hair build-up doesn’t slow your cleaning and MopExtend™ technology with 75°C hot water cleaning ensures hygienic mopping, tackling everything from pet accidents to stubborn tomato, curry or grass stains. All the while, the self-cleaning washboard 2.0 and auto maintenance features simplify upkeep, allowing kids and adults to focus on what matters most.

L40s Ultra CE: Affordable excellence

The L40s Ultra CE offers professional-grade cleaning without the premium price tag. With 13,000Pa suction, it effectively handles the realities that come with daily living, be it sidewalk debris trodden into carpets or tiny glass shards after one too many mimosas. The DuoScrub™ mopping system combined with RoboSwing™ technology ensures thorough cleaning of corners and baseboards. As for those 100 days of hands-free maintenance, you can thank the all-in-one PowerDock™’s generous 3.2L dust bag capacity and automatic mop washing for that. Finally, Smart Pathfinder™ technology and 3DAdapt™ obstacle avoidance ensure efficient navigation, making it a reliable choice for those seeking quality on a budget.
