Self-washing station
Dreame made an auto-maintenance station with the following features:
- Auto-empty. Sucks the dustbin's content into the disposable bag.
- Auto-fill water & detergent.
- Auto-wash the mopping pads and washboard. The L10s Pro Ultra, L30, and L40 use hot water to wash the pads, while others do not.
- Drying the mopping pads. The mopping pads are getting dried with hot air after mopping.
Dirt Detection senses how dirty the pads are after the mopping is done, washes them, and gets the robot back to mop the same area twice. The latest models are more precise at it.
The latest Dreame L40 cleans the washboard with hot water so it doesn't stink afterwards.
How good is mopping
The L series has advanced mopping compared to the previous generations. All robots use two rotating pads that get washed and dried via the station.
Mop Extend & RoboSwing
The Dreame robots either extend the mop along the walls and corners or swing the body for better performance.
The L10s Ultra Gen 2 and L40 twist and delve as deep as 1.57in (4cm), reaching further hidden debris under furniture. Other models extend the mop.
Rewash & Remop
With the advanced station, the robot identifies the level of the pad's dirtiness to go back and mop the same area for a second time. These models use more water.
Mop Removal
When the robot needs to vacuum a carpet, it automatically removes the mopping pads and leaves them on the station.
Mop lift
All models lift the mops when they detect a carpet; only the cheaper robots lift the pad for up to 7 mm, which is not suitable for mid-pile carpets, while the others can do so for up to 10.5 mm.
Some models also lift the roller when detecting spills.
App features
The robots have all the features you want in a modern smart robot, like no-go zones, zoned cleaning, and room cleaning, which are common for all models. There is also scheduling, cleaning sequence, maintenance information, and other options.
- Zoned cleaning and room cleaning are area cleaning. You can send the robot to clean a particular room or a zone.
- No-go zones keep the robot off certain areas like pet bowls or cluttered areas.
- Water level and suction power can be switched in the app, too.
- The later models support saving multiple maps and allow setting no-mop zones. No-mop zones are active only with a mopping attachment on and are made for avoiding carpets when the robot mops the floors, while no-go zones keep the robot off particular areas altogether.
- Also, scheduling might have additional features in the latest models.
Dreame L10s Series
The L10s Pro Gen 2 is the cheapest with no self-emptying station. It has all the same features as the L10s Pro but comes with a standard charging base in the box.
The cheapest L10s Plus comes with a base that doesn't wash the pads. It only empties the dustbin. Mopping is basic.
The affordable L10s Ultra has a different base that washes and dries the pads, but it is not as powerful as the L10s Plus. The robot is better for mopping.
The advanced L10s Ultra Gen 2 and L10s Pro Ultra have more functions, an upgraded station, etc.
Dreame L10s Pro Ultra
Dreame L10s Pro Ultra
Mopping robot vacuum
The Dreame L10s Pro Ultra is the most-featured robot in the L10 series.
It is ideal if you are looking for a robot with premium features that don't cost that much compared to what the market offers.
Dreame L10S Ultra Gen 2
Compared to the previous version, the Gen2 has more power and RoboSwing for better mopping performance, yet lacks Dirt Detection and hot mop wash.
Better for homes with carpets and some hard floor areas since mopping is not as advanced.
Dreame L10s Pro Ultra vs Dreame L10S Ultra Gen 2
- Mop Extend vs. RoboSwing
- Suction power
- Hot water for mop washing vs cool water
- Dirt Detection vs. lack of it
The Dreame L10s Pro Ultra is a better mopping robot with extra features; the Gen 2 has more power but is not as advanced at mopping as the Pro Ultra.
Dreame L20 Ultra
Dreame L20 and L30 Ultra stations have a different design. The Dreame L30 rarely comes with a discounted price tag, has more power, and uses hot water for mop wash.
The L20, L30, and L40 Ultra rise the roller, leave the mops when the robot is in a vacuum mode, and have a smart plan that adapts to the environment and adjusts settings to each room.
Dreame L20 Ultra
Mopping robot vacuum
For a hundred dollars more, you get a smarter robot that lifts the roller on spills, has a different base, automatically removes the pads, and has Dirt Detection.
Compared to the L10s Pro Ultra, the L20 Ultra doesn't wash the pads with hot water, but other than that, it has more extra features.
Dreame L40 Ultra
The Dreame L40 Ultra is the best robot in the L series with advanced smart features, bells, and whistles.
It is the only model in the series that extends and lifts a side sweeper and washes the dashboard with hot water.
The robot is the most powerful in the lineup
What to buy
Editor's Choice: Dreame L40 Ultra
The robot has a big discount, which makes it the best value for the price.
The Dreame L10S Ultra Gen 2 and Dreame L10s Pro Ultra have about the same price tag, the Gen 2 is a good buy as a vacuum while the Pro Ultra is a better mopping robot.
Since there is no price difference between these three and the other models, I would recommend getting one of these, only stick to the L40 Ultra when it on a good discount.
