Dreame L40 Ultra
Vacuum Wars Stars 3.37
The Dreame L40 Ultra is a premium robot vacuum and mop with 11,000 Pa of official suction and strong performance on hard floors and carpets. Its automatically extending, liftable side brush improves corner cleaning, while two spinning mop pads lift 10.5 mm over carpet. MopExtend and RoboSwing improve coverage along edges and beneath furniture, and the robot can leave its mop pads at the dock when vacuuming carpets. The automated station empties debris into a 3.2-liter bag, washes the mop pads with hot water, dries them with heated air, refills clean water and solution, and uses a self-cleaning tray. A camera, structured light, crossed infrared beams, and an LED support obstacle avoidance, while spinning LiDAR handles mapping and navigation. The app adds multi-level maps, virtual barriers, no-go zones, customization, and live video monitoring. Its main tradeoff is hair tangling with the standard brush, although Dreame’s optional TriCut brush substantially improved hair performance in testing. See additional info
Key Features
The L40 Ultra introduces the SideReach technology, which extends a side brush to efficiently clean wall corners and around furniture legs. In addition, the robot incorporates OmniDirt detection and MopExtend RoboSwing technologies to detect stubborn messes and clean tight spaces like under furniture and in corners.
High Suction Power
With 11,000Pa suction and five customizable levels, the L40 Ultra is built to tackle a variety of floor surfaces. This marks an increase over its predecessor, the Dreame L20, which offers 7,000Pa of suction power.
Enhanced Maintenance and App Control
The L40 Ultra offers an auto-maintenance system, including a mop cleaning function that uses 149°F hot water to wash both the mop and the washboard simultaneously, helping to reduce stains and unpleasant odors. Users can customize this feature with four different temperature settings directly through the Dreamehome app.
The app also allows for smart navigation customization, including setting pet zones, adjusting mopping levels, and controlling cleaning modes. The L40 Ultra uses a combination of 3D structured light, a built-in camera, and LED lights to navigate, with the added benefit of voice command control.
Battery Life
Additionally, it operates with a 5,200mAh battery that Dreame says will provide up to 194 minutes of cleaning on a single charge. The device covers up to 181m² (1,948ft²), making it suitable for larger homes. It also offers 30% faster charging and the option to schedule charging during off-peak hours to optimize energy use.
