The Dreame L40 Ultra Gen 2 is the newest robot vacuum and mop in Dreame’s L40 Ultra series. What distinguishes the Gen 2 from earlier L40 Ultra models is the extendable side brush and mop, which reach into corners and along edges. The brush and mop extend from the side of the robot when it detects walls or corners, so it can clean tight edges in a single pass. Although the L40 Ultra Gen 2 keeps the self-cleaning dock and effective suction the series is known for, the extending features add more reach to your cleaning routine.

A powerful robot vacuum that can help clean just about any home
The L40 Ultra Gen 2 delivers 25,000Pa of Vormax suction, which is enough to pull up pet hair and general debris from hard floors and carpets. The DuoScrub mopping system uses two oscillating mop pads that physically scrub the floor instead of just dragging across the surface. Mop lifting raises the pads about 10mm above the floor when the robot detects carpet, so the mop doesn’t drag wet pads across your rugs. It also includes four carpet modes, with suction boost for deeper cleaning and carpet avoidance to keep the mop off rugs.
The two extending features on the L40 Ultra Gen 2 are SideReach Vacuuming and MopExtend RoboSwing. The side brush extends outward when the robot’s sensors detect a baseboard or corner, and it sweeps along the wall as the robot passes. MopExtend RoboSwing swings the mop pad up to 1.57 inches from the robot’s body to reach the same wall edges and corners. Both extensions work automatically during cleaning, so the robot adjusts its reach whenever its sensors pick up an edge, and you don’t have to change anything in the app.
