Dreame is well known for its robot vacuums, with the Dreame X50 Ultra being one of CNET’s top picks due to its ability to cross obstacles with its lift system and advanced mapping and navigation. This feature, first unveiled at CES 2025, is great if you have thresholds in your home, but it's also costly, running around $1,700 at full price. Dreame’s new L40s lineup aims to make this handy feature more affordable, bringing the lift system to the L40s Ultra and premium navigation and multifloor mapping to the rest of the lineup.
I spent a few hours with Dreame’s new robot vacuums to see how they perform. I also looked at Dreame's more premium Aqua 10 Series, which incorporated the threshold-crossing feature and made it even better. Here’s what impressed me most.

Premium features across the L40s lineup

The new Dreame L40s shares a couple of premium features across the lineup. The main feature is on the sensor and software side, with all three new models getting the Pathfinder smart navigation and 3DAdapt obstacle avoidance. These give them smarter mapping and route planning for cleaning sessions and more advanced sensors to detect and navigate around obstacles. In the app, you’ll be able to set customizable cleaning zones and virtual boundaries if there’s somewhere you don’t want the robots to go.
There’s also support for multifloor mapping, making it easier for a single robot to tackle multiple levels, though you’ll still need to move them since they can’t climb stairs quite yet. Naturally, you get smart home integration with support for third-party voice assistants, including Alexa and Google Assistant.
On the hardware side, all three vacuums have a 5,200-mAh extended battery, which should provide more cleaning time. They also all get the Vormax suction, which should provide stronger suction that can adjust to your flooring type. All the new robots also come with self-empty and auto-refilling docking stations.
