Dreame L40 Ultra AE

A robot that vacuums and mops with two pads, paired with a dock that takes care of most of the upkeep: it empties the dust into a 3.2-litre bag that lasts up to 100 days, washes the pads with water at up to 75 °C, dries them with warm air and adds detergent on its own, from a compartment meant for the official solution only. It also refills the robot's tank. The dock's two tanks, 4.5 litres of clean water and 4 of dirty water, are filled and emptied by hand: the kit that connects the dock to the plumbing is sold separately and available only in some regions.

The box holds two main brushes to swap between: a rubber one that lifts to let bulky debris such as kibble and oat flakes through, and the TriCut, whose built-in blade cuts long hair before it wraps. A laser sensor builds the map; at the front, structured light and a colour camera recognise obstacles, with an LED light for dark rooms. The body is 9.7 cm tall. The pads extend beyond the robot's outline once the feature is enabled in the app. On carpets, detected by an ultrasonic sensor, the pads lift by 10.5 mm: enough for short pile, while for pile above 3 mm the guidance is to have the app avoid them.

On board there is an HD camera, an infrared camera and a microphone: the Dreamehome app lets you watch and talk at home remotely, and a mode finds the pet and takes a photo. European users' data is stored on servers in Germany. Wi-Fi is 2.4 GHz only; the robot also works with Alexa, Siri and Google Home. The main brush is replaced every 6–12 months, the filter and side brush every 3–6, the pads every 1–3; the filter rinses with water. The French repairability index is 8.2 out of 10, with zero points for how long spare parts stay available.
