L40 Ultra AE
A 2024-generation full-dock Dreame that Poland still sells: 19,000 Pa, a lifting rubber brush with TriCut, an AI camera with structured light, a 75 °C wash with drying, refill and detergent, a 395 ml bin and 180 minutes a charge, for 2,099 zł.

Our verdict
The L40 Ultra AE is last year's mid-range Dreame, 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 the tank from 4.5 litres, doses detergent, empties for 100 days, and reads the colour of the wash water to decide how hard to wash and whether to send the robot back over a dirty patch. The pads extend at the edges and lift 10.5 mm, though the page gives no threshold height and no noise figure, and carpet is detected by ultrasound without a stated suction boost. At 2,099 zł it is the only shop price among those we read; Germany has a refurbished unit only.
