Dreame L40s Ultra CE

What testers say about the Dreame L40s Ultra CE

Vacuum Wars and Just A Dad Approved disagree about the Dreame L40s Ultra CE on nearly everything except its eyesight. Vacuum Wars placed its vacuuming above the lab's median, noted that it pulled embedded sand out of carpet better than most, and scored the mopping 3.02 out of 5, ahead of the 2.58 midpoint. Just A Dad Approved, living with it day to day, gave both jobs 6 out of 10, under its usual 7 for vacuuming and 7.5 for mopping. Part of the gap is the station: it rinses the pads cold, and that tester found they did not come out as clean.

On obstacles the two agree. Vacuum Wars counted roughly a third of its 24 test objects avoided and gave 1.22 out of 5, about half its median of 2.375, and Just A Dad Approved called the avoidance a bare pass. In a home that means cables, socks and pet bowls have to be cleared away first.

The 13,000 Pa on its spec sheet falls well short of the 20,000 Pa normal for robots with a full wash-and-empty station, though the carpet result shows the figure undersells it. Runtime is 260 minutes, an hour longer than the class median, enough for a large floor in one go. The body rises 4.1 inches, 0.3 inches above most, so measure a low sofa first.

Each point sums up, in our words, the review of the test it names, and its link leads to that review. We do not summarize RTINGS or Wirecutter: their lists are linked above.
