What you can expect from the Dreame L40 Ultra Gen 2
What testers say about the Dreame L40 Ultra Gen 2
Two labs watched the Dreame L40 Ultra Gen 2 meet clutter and came away with different marks. Vacuum Wars saw it dodge just 2 of 24 objects and marked obstacle avoidance at 0.31 on a five-point scale, where 2.375 is that lab's ordinary result. Just A Dad Approved, three months into home use, settled on 7.3 out of 10, a shade below its regular 7.5, yet reported the robot stuck around chair legs repeatedly. That tester points to the cause: this second generation dropped the camera the first L40 Ultra carried. Socks, cables and toys want lifting before it starts.
On a clear floor it does better. Of the sand Vacuum Wars ground into carpet, 90% came back out, more than its average robot recovers, and the side brush swung out far enough to clear corners in the Just A Dad Approved home. Dreame's motor rating is 25,000 Pa beside a midpoint of 19,750 Pa for robots docked at a station that also launders the mop, and one charge lasts 231 minutes, about half an hour past the ordinary 200 minutes.
Mopping split the labs a second time. Vacuum Wars, with dried stains lifting well, went to 3.14 out of 5, past its 2.58 norm. The other tester stopped at 7.2 out of 10 and found the pads wiping more than scrubbing. The station is a tall one at 23.2 inches, with 19.7 inches as the common height, so the gap under a shelf is worth measuring first.
