Price history
Dreame L40 Ultra A specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
Dreame · on the market since March 2026
Consumables: a 3.2 l dust bag in the station, which lasts up to 100 days.
Dimensionsrobot and dock
From the published dimensions. The robot passes under furniture with 10 cm of clearance or more.
Suction and brushes 4 facts
- Suction power
Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.
- 24,000 Pa
- Anti-tangle brush
A brush that guides hair to the side instead of letting it wind around the shaft. It saves the cutting work in homes with long hair or pets.
- yes
- Carpet detection
- detects carpet and boosts suction
- Suitable for pet hair
- yes
Mopping 3 facts
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.
- spinning pads
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 10 mm a medium pile stays dry.
- 10.5 mm
- Mop extends to the edges
The pad slides out along a wall or a kickboard, so the last few centimetres are mopped as well.
- yes
Dock 9 facts
- Empties the dust bin
The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.
- yes
- Bagless
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.
- no
- Dust bag capacity
How much the dust bag in the dock holds.
- 3.2 l
- Dust bag lasts
How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.
- up to 100 days
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes
- Dries the mop
The dock dries the mop afterwards, so it does not sit there wet and start to smell.
- yes
- Clean water tank
The clean water tank in the dock, which wets the mop.
- 4.5 l
- Dirty water tank
The tank that catches the dirty water from the mop. You empty this one yourself.
- 4 l
- Dock height
The height of the dock. Mind a shelf or a window sill above it.
- 59 cm
Navigation and obstacles 4 facts
- Navigation
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognises more.
- LiDAR turret
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- 3D sensor (structured light)
- Climbs thresholds up to
The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.
- 20 mm
- No-go zones
- zones in the app
Robot 4 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 9.7 cm
- Robot diameter

- 35 cm
- Robot weight
What the robot weighs. It counts most if you carry it up a staircase every day.
- 3.91 kg
- Dust bin in the robot
How much dust the robot holds before you empty it. It matters less with an auto-empty dock, which empties the bin after every run.
- 300 ml
Battery 2 facts
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 5,200 mAh
- Runtime per charge
How long the robot cleans on one charge, at its quietest setting. After that it recharges and carries on where it stopped.
- 230 min
Smart features and warranty 1 fact
- Voice assistants

- Alexa, Google Assistant, Siri
