Review of Dreame L10s Ultra and Dreame L20 Ultra - robotic vacuum cleaners with mops, auto-cleaning and “Alice”
Miscellaneous / / November 20, 2023
Models with top-end capabilities, reminding us that our laziness is still an engine.
Robot vacuum cleaners are developing even faster than modern smartphones. Just recently we were amazed at how these “pancakes” deftly avoid obstacles and roll cats, but now they polish floors, change the water themselves, and even recognize animals. The Dreame L10s Ultra and L20 Ultra Complete, which came to us for testing, can do all this and much more. These are real flagships - big, powerful and very smart, although not without flaws. Let's talk about the devices and compare their performance.

The Dreame L10s Ultra vacuum cleaner comes in a double box. At first impressions it seemed very large and heavy, but then the Dreame L20 Ultra arrived, and we realized: this is where the big heavy box is.
The weight will also surprise you:
- Dreame L10s Ultra — 18.6 kg;
- Dreame L20 UltraComplete - 27.5 kg.
Why so much? Because inside each box, under a layer of foam plastic and seals, is not only the vacuum cleaner itself and its docking station, but also a number of consumables. All of them are neatly laid out in different cardboard packages - this is convenient both for transportation and for subsequent storage.
Dreame L10s Ultra Kit:
- vacuum cleaner;
- docking station with installed bag;
- side brush;
- spare disposable dust bag;
- two round mops with holders;
- container with detergent;
- cleaning brush with a knife in the handle.
All this is complemented by a station power cord with a Euro plug and a fairly detailed user manual, including in Russian.
The Dreame L20 Ultra, which is positioned as a higher-level solution, has approximately the same basic kit, except that the manual brush is different.
But in addition to the standard set of consumables, the kit includes a box of additional accessories - this is what is reflected in the model name with the Complete prefix. And it's just a song.
Set of additional accessories for Dreame L20 Ultra:
- garbage bag - 3 pieces;
- filter for vacuum cleaner - 3 pieces;
- main roller brush - 1 piece;
- side brush - 2 pieces;
- container with detergent - 3 pieces;
- mops for wet cleaning - 12 pieces.
Each docking station is already equipped with two large containers for water - clean and dirty. The clean one is used for wet cleaning, and both vacuum cleaners themselves are refueled at the station as needed, and the dirty one is formed when washing the mops.
After cleaning, these furry rollers are dried with hot air. For this procedure, each model has a special removable plastic platform (pictured above, on the right), onto which the robots climb when refueling - everything happens automatically without your participation.
The larger Dreame L20 Ultra base has a removable base for the vacuum cleaner to move in - it’s literally a simple plastic bridge. But on the L10s Ultra, a similar part is part of the base itself. These differences are dictated only by ease of transportation and practicality.
Appearance of vacuum cleaners
The vacuum cleaners themselves are approximately the same size, 35 cm in diameter and almost 10 cm in height. The Dreame L20 Ultra has a slightly higher lidar tower.
In front, both models have a movable bumper, which has not only traditional infrared sensors, but also a video camera. In the case of the Dreame L20 Ultra, lighting is also provided - real LED headlights for orientation in the dark, but more on that later.
On the side of the small side brush on the bumper there is another sensor with which vacuum cleaners determine the distance to vertical surfaces. This is a kind of parking sensor to carefully move along walls and furniture.
Also at the end, closer to the back of the robot, there are holes for the speaker, a channel for sucking dust from the vacuum cleaner, covered with a plug, and another number of holes for air outlet. These elements have different designs, but the purpose is identical.
On the back there are connectors, a pair of charging contacts, a proximity sensor and a small hole for automatic refilling with water.
On the Dreame L10s Ultra, most of the top panel can be folded back, while on the Dreame L20 Ultra, the entire top cover can simply be removed: it is magnetic. Under these panels is a garbage container with a removable HEPA filter, which can be easily removed, like in any other robot vacuum cleaner.
There, under the cover, there are QR codes with which devices connect to mobile applications, a Wi-Fi connection indicator and a recessed reset button to factory settings.
The chassis in both cases is standard: two drive wheels with pronounced tread and a support roller closer to the nose. Along the edges there are four surface sensors that help the robots not fall off the steps.
In front of the support roller there is another round sensor, which is responsible for recognizing carpets. By the way, it works great.
The main brush is a soft rubber brush with a V-shaped texture and without the usual bristles. You won’t have to scratch the hair out of it, unless it gets wrapped around the metal edges, but that’s the lesser of two evils.
For wet cleaning Two round mops are attached to the bottom of the vacuum cleaner. It's literally microfiber with a plastic holder. Such round pieces are fixed with magnets - no latches or twists, everything is very simple.
Mops are wetted from a small built-in container that is not accessible. It refills automatically when returning to base through the previously mentioned hole in the rear of the case. The tank capacity inside is small, only 80 ml for each model.
Don’t think that 80 ml is literally a couple of meters of area. In the case of moving mops, water is consumed more economically, because there is no need to soak a large rag, as in classic washing vacuum cleaners.
Construction of self-cleaning stations
Parking docking stations for vacuum cleaners work the same way: they suck out debris into a built-in bag, charge the robot, fill it with water and rinse the mops, literally turning clean liquid into dirty. Dirty water is pumped into a dark tank, which must be emptied periodically. In the light one, you just need to add water as needed - straight from the tap will do.
As for the water supply to the vacuum cleaner itself, everything is also quite simple. Both Dreame L10s Ultra and Dreame L20 Ultra neatly and accurately “stick” into the water supply channel, which is located next to the charging connectors. No leaks or drops form during refueling - everything is reliable.
A container with a cleaning agent is also inserted into the station between the water tanks - they are different in shape and capacity. Dreame L10s Ultra has 300 ml, and Dreame L20 Ultra has 450 ml.
You can add branded cleaning agent as needed through the top valve, you can simply change the container itself, or you can not use it at all. Both vacuum cleaners work great without it.
It is not recommended to use regular floor cleaning products that are not intended for Dreame vacuum cleaners. Heavily foaming compounds may shorten the life of the device.
The Dreame L20 Ultra also has a niche for a brush next to the detergent compartment, the handle of which contains a knife for cutting hair and threads wound around the moving elements of the vacuum cleaner. The L10s Ultra has a similar tool in the form of a brush, but you will have to store it separately (and always lose it).
In front, behind the chrome cover of each base, there is a compartment for removing the bag. On the Dreame L10s Ultra, this cover simply presses down, so if you pull one edge, it will literally fall off. An additional miniature brush-knife is attached to it on the reverse side.
On the Dreame L20 Ultra, the cover is removed only after switching the special toggle switch under it. And inside there is not only the main bag, already installed, but also an additional one in a special compartment on the side - a nice little thing.
At the back of each docking station there is a power switch and a cable socket that faces down. In the case of the L20 Ultra, special “ears” are also provided for winding wiresso that its excess part does not lie on the floor.
On paper, the dimensions of the docking stations differ noticeably, but the difference does not seem to be that big:
- Dreame L10s Ultra — 340 × 423 × 568 mm;
- Dreame L20 Ultra - 426 × 499 × 606 mm.
In fact, the L20 Ultra station looks almost twice as wide. Guests who came to us compared it either to a coffee machine (apparently from a coffee shop) or to a mini-fridge. In a small room it will look very bulky.
Both bases can be placed close to the wall, but it is important to take into account that there should be at least 1.5 m of free space, and at least 0.5 m on the sides. This is necessary for correct parking of vacuum cleaners.
You also need to leave a reserve above the base, because the top cover in both cases is hinged. Accordingly, push the station, for example, under a TV stand, shelf or windowsill wouldn't be very smart. Each time you change the water, you will have to move the base along with the robot.
However, in the case of the Dreame L20 Ultra, you can completely forget about fiddling with water. To do this, you need to purchase an official kit for connecting the base to the water supply. It includes two other containers (to replace the original ones) and related parts that allow you to connect the supply of clean water and drain dirty water (for this purpose, there are connections at the back). That is, the principle is exactly the same as with a washing machine.
But in such a scenario, you need to wisely choose the location of the base, because in the middle of the room it will be problematic to organize the supply and drainage of water. A kitchen or even a room adjacent to the kitchen may be more suitable here. boner.
Connection and control
Both vacuum cleaners can be used without applications or connecting to Wi-Fi: on the body of the robots there are buttons to start cleaning (local or full) and return to recharging. The docking stations also have buttons for moving the vacuum cleaner off the platform, starting cleaning, and drying mops.
But it is better, of course, to install an application to control all possible functions. Dreame L10s Ultra can be connected to Dreamehome or Mi Home, while Dreame L20 Ultra only connects to dreamhome — we tested both models with it.
Dreame Technology (SuZhou) Co., Ltd
To enter pairing mode, press and hold the “Power” and “Home” buttons (on the vacuum cleaner itself) for 3 seconds until a beep sounds. Next, you will need a quick registration with confirmation of your email address or mobile phone number. You can also log in using your Google account. There were no problems with this.
Dreamehome supports the Russian language, albeit with errors. Using the application is quite comfortable - don’t let the low rating on Google Play and the App Store scare you.
When you first start and add a vacuum cleaner, Dreamehome will give several recommendations and ask if there are any animals at home - so that the robot will carefully avoid possible “mines” on the way. Next, the application will offer to start a quick wet cleaning and draw a map of the room. In this starting mode, the vacuum cleaner travels around the entire perimeter of the available space to outline its boundaries.
Customization and smart features
In Dreamehome you can customize literally everything you might need: cleaning mode, suction power, humidity mop, the sequence of cleaning the premises and even the area after which you need to return to the base for washing mop
The more expensive Dreame L20 Ultra also has two separate CleanGenius cleaning modes - daily (normal) and Ultimate, in which the robot tries to identify the dirtiest areas and repeatedly mops there (usually this is Y slabs or front door).
Self-cleaning also has a number of settings. For example, you can choose the frequency of cleaning the dust collector or the amount of water used. This applies to one model as well as the other.
You can even set up the drying of mops and the suction of dust into the station, so that, for example, the base does not suck dust from the container after each cleaning.
After building a map of the room, you can set up virtual walls, mark restricted areas and adjust carpet areas. This is necessary so that on a fluffy surface the robots can increase the suction power and lift the mops. But in general, both models do this automatically, signing rooms and zones. They recognized the door mat and the bath mat without any problems (dot markings on the map).
In addition to carpets, vacuum cleaners perfectly recognize and label all obstacles that interfere with cleaning, including wires, children's toys, shoes and even scattered socks (they are referred to as “fabric” on the map). According to the manufacturer, the L20 Ultra can detect as many as 55 objects.
Both models easily recognize people's legs without trying to probe them with the bumper. Therefore, while you stand at the stove, the vacuum cleaner will not try to crush you. The same applies to many other obstacles, such as chairs.
The AI Action camera with 3D scanning function is responsible for this “vision”. She's trying to recognize pets and everything they leave behind. The dog was not at home, so we leave the assessment of the accuracy of recognizing dog mines to you.
Dreame L20 Ultra can detect obstacles even in complete darkness because it has LED headlights. They turn on automatically even when driving under the bed.
Also, in both models you can get direct access to the camera - directly from your smartphone. That is, you can literally take a selfie with a vacuum cleaner or monitor the movements of the device, watching the picture in real time. Remote movement control is also available, including by clicking on a destination on the map.
Please note that access to the camera is possible using a digital password, which is created during the first setup. And the vacuum cleaner itself during shooting indicates that the camera is activated. Initially, everything is in English, but in the settings there is a translation of the voice and all sound alerts into Russian.
In the same section, you can select a children's mode with disabling buttons on the base and the robots themselves. Then you can control cleaning only from the application.
And of course, you can set up a convenient schedule for cleaning, including separate scenarios for each room. So, the bedroom can only be vacuumed, but kitchen - wash. Moreover, you can save a script for cleaning a specific area in the apartment and launch it with one click from the application (for example, cleaning the hallway after guests).
To simplify operation as much as possible, Dreame L10s Ultra and Dreame L20 Ultra can be connected to a Yandex smart home to control voice commands using Alice.
There are three actions available for scenarios: start cleaning, end and pause. Everything works great. Checked with "Yandex Station 2». The main thing is not to force the vacuum cleaner to work during cleaning cycles (while drying mops, you can).
Fun fact: a robot vacuum cleaner can easily stop the music on the Alice speaker, but unintentionally, of course.
The thing is that “Alice” has recently understands commands without calling them by name. And as soon as you pause cleaning, the Dreame vacuum cleaner says “Pause,” and “Alice” obediently obeys and stops the track being played. Such is the conflict of technologies.
During the first cleaning, vacuum cleaners inspect the room and divide it into small square zones, which alternately pass like a snake. The entire route is displayed in the application in real time.
The suction power in both cases is top-notch even by the standards of flagship models:
- Dreame L10s Ultra — 5 300 Pa;
- Dreame L20 Ultra - 7,000 Pa.
For comparison, the Xiaomi Robot Vacuum X10+ robot vacuum cleaner, which is similar in class, has a power of 4,000 Pa. In other words, with Dreame you don’t even have to worry about the quality of dry cleaning. Both devices work great on both bare and shaggy floors. rugs (not very high).
When hitting a pile surface, both vacuum cleaners increase suction power to better cope with sand and stubborn dust. And, of course, in this mode the robots begin to “take off,” that is, they make noticeably more noise (the video above has sound).
The autonomy of both models in dry cleaning mode is also impressive:
- Dreame L10s Ultra — 210 minutes (3 hours 30 minutes);
- Dreame L20 Ultra — 260 minutes (4 hours 20 minutes).
This is more than enough even for huge apartment. The first model on one charge can cope with an area of up to 200 square meters, and the second - up to 300. The garbage is quickly sucked into the bag, but this, of course, is also a noisy process.
On average, the Dreame L10s Ultra bag fills in about 60 days, while the Dreame L20 Ultra takes about 75 days. The time depends on the area being cleaned and the frequency of operation of the device.
A life hack for those who don’t want to bother with replacing bags: you can shake out the dust from the vacuum cleaner container yourself by turning off the suction into the bag in the app. But if you had such a thought, then perhaps you shouldn’t spend money on an expensive model?
And the bags themselves are very easy to change. There is no contact with debris, except that the plug on the output channel needs to be wiped periodically.
Most modern vacuum cleaners are called detergent if they simply drag a wet cloth along with them. It would be more logical to call such models “wetting”. Although it doesn't sound very good, of course. Dreame L10s Ultra and Dreame L20 Ultra are much closer to the washing type, because they actually wash.
Their mops rotate at speeds of up to 180 rpm. This, of course, is not polishing, but rub it off a little dried spots on the bare floor they can. For complete happiness, vacuum cleaners do not have enough weight to impart such a pressure washer. But this is probably already a foundation for the future.
In general, even in the mode of abundant wetting, the devices do not leave strong streaks or drops. The surface remains wet, but not so wet that you can slip.
The mops are raised in front of obstacles and mats. So the robot automatically switches to dry cleaning mode (in the video above).
Separately, it is worth highlighting the MopExtend technology of the Dreame L20 Ultra. It allows you to pull out one of the mops to thoroughly clean the floor in the corners of the room. The robot's sensors determine when this is necessary and give a command to “stick out its paws.”
The liquid in the built-in reservoirs is enough for about 20–25 square meters. Then the devices return to refuel, fill the tank full from the base and continue washing from where they left off.
After wet cleaning is completed, the mops are automatically washed at the base and dried with hot air for a couple of hours so that there are no smells. In this mode, they are constantly scrolling and blowing air - this is audible, but the volume is not critical, a slight hum. The process of water renewal is much more noticeable - as if the batteries are turned on before the heating season (watch the video below with sound).
Well, after washing the mops and refueling the robot, all that remains is to pour the dirty water out of the dark container of the base (pictured below) and add clean water into the light one. But you don’t need to do this very often, once a week or two, depending on how you use the vacuum cleaner and on what area.
Maintenance and care
In addition to changing the water and changing the bags much more rarely, the devices will require little but regular maintenance. It is important to wipe the sensors on the body, periodically wash the container in the vacuum cleaner itself and both water tanks. Also, don’t forget to remove hair and debris from the wheels - after all, they are not automatically cleaned.
In the case of the Dreame L20 Ultra, we also recommend wiping the plastic tray on which the mops rotate while drying. There may be stains left from dried drops of dirty water. With the Dreame L10s Ultra, this problem occurs less frequently (the washing and drying processes of vacuum cleaners are slightly different).
As for replacing consumables, you can monitor this in the application. There, the wear of all replaceable elements is estimated based on operating hours - in the settings of the “Remaining time” section (hello, localization).
The remaining cleaning agent is removed there. The manufacturer sells blocks with this solution separately, but in the case of the Dreame L20 Ultra, you won’t remember them very soon (the set includes four flasks, that is, 1.8 liters in total).
For robotic vacuum cleaners to become as autonomous as possible, they just need to learn how to teleport garbage from the dust collector somewhere into a bag under the sink, or even better - directly into an outdoor container. But such technologies are not expected in the near future, so we have to be content with what we have. And there is literally everything else.
Both models demonstrate flagship technologies in the robot vacuum cleaner segment. They have almost everything that the market can offer today.
The main advantages of both models:
- powerful dry cleaning of any coatings;
- practical main brush;
- high-quality floor cleaning;
- possibility of using detergent;
- accurate recognition of obstacles and carpets;
- automatic water refilling and dust suction into the bag;
- fine-tuning operating and cleaning modes;
- thoughtful drying of mops;
- camera with direct access from a smartphone;
- voice control via Alice.
With all this, the Dreame L20 Ultra is one step ahead in terms of skills: it is a truly top-end model, although more expensive. Its cost in the Complete version (with a set of accessories) is 109,990 rubles versus 79,990 for the Dreame L10s Ultra.
The overpayment comes for several key advantages:
- higher suction power;
- more thorough cleaning of floors due to CleanGenius modes and MopExtend technology;
- better recognition of obstacles in the dark;
- higher autonomy;
- ability to connect to water supply;
- large set of consumables.
Of course, both models are quite expensive by modern standards, but their purchase is a long-term investment that will definitely pay off where it is justified. For a small studio or one-room apartments the capabilities of such units are absolutely redundant. It's like taking the most expensive and largest iPhone just to make calls and chat via instant messengers. Stupid.
But if you have a cottage or some kind of three-ruble apartment with a huge living room and soft carpets and “Alice” in each room, then both Dreame L10s Ultra and Dreame L20 Ultra will open up to their fullest. Only in large areas with different surfaces will they be able to show off all their advantages, and then you will really appreciate them.
Well, as for the shortcomings, here we can note that the localization of the Dreamehome application is not the most accurate, the need wiping trays under vacuum cleaners, noisy cleaning, and the too large docking station of the Dreame L20 Ultra (it’s really huge). That's all.
- Dreame L10s Ultra available in "M Video», «El Dorado», DNS, «Technopark», re: Store, «Everythingsmart" And manufacturer's official website. All consumables are there too.
- Dreame L20 UltraComplete can also be purchased atM Video», «El Dorado», DNS, «Technopark», re: Store, «Everythingsmart" And manufacturer's official website.
