Dreame L40 Ultra CE review

Our verdict
The L40 Ultra CE is the cheapest full-dock Dreame in this catalogue, and the dock is the reason to buy it: it empties the bin into a bag for 100 days, washes the two spinning mops, dries them with room air and refills the robot from a 4.5 l tank, the same maintenance list as Dreame's dearer stations. The robot is the modest part. 13,000 Pa sits at the bottom of the current range, the TriCut brush cuts hair rather than letting it wrap, the mops lift for carpet, where the app offers carpet strategies including a suction boost, and it navigates by laser distance sensors with 3DAdapt structured light for obstacles, which copes with furniture but recognises no objects. The 5,200 mAh battery is rated for 260 minutes of quiet vacuuming. Dreame's Polish page prints no dimensions, weight, dust bag size, mop lift height or warranty term, and the mop drying is unheated. For a flat with hard floors and a few rugs it does the daily job.

In detail
Suction and brushes
The manufacturer rates the suction at 13,000 Pa. That is less than most of the 114 robot vacuums we list. The main brush is the tangle-resistant type, with one side brush. On carpet the suction rises automatically.
Mopping
Mop system: twin spinning pads. It lifts the mop over carpet.
Navigation and obstacles
It navigates by LiDAR and avoids obstacles with structured light. No-go zones can be drawn in the app.
The dock
The dock empties the bin, washes and dries the mop and refills the water tank. The dust bag lasts about 100 days.
Battery, charging and noise
One charge runs up to 4 h 20 min. The manufacturer publishes no noise figure.
