Our verdict
The L40 Ultra AE is the mid-range Dreame that the Polish shop still sells, and its page is the most complete in this batch. It vacuums at 19,000 Pa with a rubber main brush that lifts for mopping and a TriCut brush for hair, empties into a 395 ml bin, and runs 180 minutes or 168 m² on a 5,200 mAh battery in standard mode. An AI camera with 3D structured light and an LED recognises more than 120 obstacle types, and a fixed LiDAR keeps the height at 97 mm. The dock washes the pads at 75 °C, dries them with hot air, refills from a 4.5 litre tank, doses detergent, empties for 100 days, and reads the colour of the wash water to choose one of 32 wash volumes and send the robot back over a dirty patch. The pads extend at the edges and lift 10.5 mm. The page gives no threshold height or noise figure, carpet detection is ultrasonic without a stated boost, and Germany sells it refurbished only.

In detail
Suction and brushes
The manufacturer rates the suction at 19,000 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. The onboard bin holds 395 ml.
Mopping
Mop system: twin spinning pads. It lifts the mop 10 mm over carpet. The mop swings out to reach along walls.
Navigation and obstacles
It navigates by LiDAR and avoids obstacles with camera + depth sensor. 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 3 h. The manufacturer publishes no noise figure.
