The Dreame L10s Ultra is a premium robot vacuum. It boasts an RGB-color camera and a structured light sensor for real-time hazard avoidance. It also includes a lifting mopping system that allows it to vacuum carpets and clean bare floors without getting the former wet, as well as a multi-function dock that not only empties the vacuum's dustbin but also refills its water tank and washes and dries its mopping pads.
The Dreame L10s Ultra is okay for bare floors. Its debris pickup performance on hard floors is great overall, but its mop feature is nowhere near class-leading, especially if you don't add any cleaning solution to its clean water tank. On the upside, its advanced multifunction dock negates a lot of the standard day-to-day maintenance you might expect with a robot vacuum, and its wide variety of in-app automation features means that you can basically tailor every facet of the vacuum's performance to match your needs. Its LIDAR sensor maps quickly, and its front-facing RGB camera is quick to spot and identify obstacles, but this won't necessarily stop it from getting stuck in some places.
The Dreame L10s Ultra is an alright choice for homes with low-pile carpet. Debris pickup performance on this surface type is mediocre overall, even with its automatic surface detection system that can boost suction on carpets. That said, if you don't plan on using it for any larger messes, it provides a pretty painless user experience. Its mop lift system raises its mopping pads when passing onto carpets or rugs, so there's no need to fiddle with the device if you want it to run both vacuuming and mopping jobs within the same cleaning cycle. Its multifunction dock does cut down on 'normal' maintenance routines since you'll no longer have to empty its internal dustbin, refill its water tank, or clean its mopping pads manually. However, there are still quite a few components that you need to wash periodically.
The Dreame L10s Ultra delivers unremarkable overall performance on high-pile carpet. While it does have surface sensors that enable it to automatically boost suction on carpets, overall debris pickup performance isn't spectacular, so it'll need to make one or two extra passes to get everything. Its real-time hazard avoidance system is good at identifying thick carpets on which the vacuum can get stuck, but this won't necessarily prevent the vacuum from trying to clean them anyway. Thankfully, it does have a wide variety of carpet-specific cleaning functions. Its mop lift system raises its mopping pads on carpets, so you don't have to worry about stopping the vacuum to remove them if you want it to scrub stains on hard floors and clean your carpets in one go.
The Dreame L10s Ultra is a poor option for pet owners. Its pet hair cleaning performance is pretty poor on carpeted floors, and it does a bad job of sealing in fine allergens as it cleans. It'll also need to make an extra pass to fully clear away any dried-on stains, and that's if you decide to mix detergent into its clean water tank; its stain-clearing performance is quite poor if the system uses only water. That said, this vacuum operates very quietly, so it won't be too much of a disturbance to pets that are easily startled. Thanks to the built-in RGB camera, you can also use it to keep an eye on your pets while you're away from home.

The Dreame L10s Ultra is a high-end robot vacuum. It's quite feature-packed for something in this price bracket, with an RGB-color camera for real-time hazard identification and avoidance, a dynamic mop system that it can raise on carpeted floors, and its multifunction dock, which empties the vacuum's dustbin, refills its internal water tank, and washes and dries its mopping pads. While it isn't the most powerful machine on the market nor the most effective in terms of debris pickup, it does offer a wide array of features that make for a hands-off user experience.

The Roborock Q Revo and Dreame L10s Ultra each have their own strengths and weaknesses. They're very close in general specifications, which isn't overly surprising considering both brands used to share Xiaomi as a parent company. Both vacuums are bundled with multi-function docks and share similar motor and battery specifications. That said, their hazard-avoidance systems have a major difference: the Dreame has an RGB camera and structured light sensor, whereas the Roborock has only the latter. In practice, this makes the Dreame faster and more accurate in identifying obstacles and allows you to use it as a roving security camera. On the other hand, despite also sharing pretty similarly-designed mopping systems, the Roborock is much more effective in dealing with stains.
The Roborock S8 Pro Ultra is a slightly more capable robot vacuum than the Dreame L10s Ultra. The Roborock's twin-roller head is better at dealing with pet hair, and its Reactive 3D hazard detection system is better at spotting obstacles, making it less likely to get stuck on obstacles than the Dreame. Its brushroll lifting system also prevents the rollers from getting dirty as it mops. However, it's worth noting that the Dreame's multi-function dock, which has similar capabilities to the Roborock's RockDock, is taller and narrower, making it a little easier to fit in tight spaces.
The Dreame L10s Ultra and Roborock S7 MaxV are both hybrid vacuum mops with relatively advanced real-time hazard avoidance systems. With that said, you'll need to upgrade to the pricey Roborock S7 MaxV Ultra to get something that's bundled with a multifunction docking station. Meanwhile, the Roborock does deliver superior debris pickup performance on most surface types, and its mopping system does a better job of scrubbing away stains. The Roborock's hazard avoidance system is also better at avoiding obstacles.
The Dreame L10s Ultra is a more feature-packed vacuum than the Roborock S8+/S8, but the latter is simply a stronger overall performer. The Dreame is bundled with a more advanced multifunction dock that not only empties its dustbin but also refills its water tank and cleans and dries its mopping pads; you'll need to upgrade to the more expensive Roborock S8 Pro Ultra to get these features. The Dreame vacuum also has a nominally more advanced hazard avoidance system than the regular S8, with the addition of a color-capable camera. That said, the Roborock clears away more debris on carpeted floors, and its twin roller head is far more effective in cleaning pet hair. Its mopping system is also far more effective; the Roborock vacuum's scrubbing does a better job of dealing with stains with just water compared to the Dreame's system, which performs best with the addition of detergent.
The Dreame L10s Ultra is better than the eufy X10 Pro Omni. They're similar in terms of features. Both are hybrid vacuum/mops bundled with multifunction self-empty docks that refill their respective water tanks and wash and dry their mop pads. That said, the Dreame is more effective in dealing with debris on most floor types, and it's less prone to getting stuck compared to the eufy. The Dreamehome app also has a slightly more comprehensive suite of features than the eufy Clean app.
The Dreame L10s feels very well-built. It's made mostly from high-grade plastic with a mix of glossy and matte finishes and has a dense, solid feel. There are a few obvious weak points, though the dustbin and trim piece covering the front-facing camera are made of thin plastic that feels rather brittle.
The vacuum itself is also quite easy to take apart and put back together; the side brush, dustbin, and brushroll are all quite easy to remove and reinstall back into the vacuum itself.
This vacuum has quite a few parts that you need to clean regularly, though thankfully, everything is pretty easy to access.
The Dreame L10s Ultra's mopping systems also have their own fair share of required upkeep.
Any component washed under water should dry for at least 24 hours before being reinserted in the vacuum.
The Dreame L10s Ultra incurs high recurring costs.
You can also purchase an Accessory Kit bundle, which comes with:
You can also buy a cleaning detergent, which is injected into the clean water refill tank in a precise quantity. You can add it to the clean water supply by pouring it into a slot at the back of the dock. You can buy a three-pack of 10.6oz (300 mL) bottles here.
The Dreame L10s Ultra has a relatively large footprint. That isn't down to the vacuum itself, which is similar in shape and size to most other models on the market, but rather its multifunction dock, which is much larger than more conventional self-empty docks due to the addition of two separate water tanks.
The Dreame L10s Ultra's debris capacity is impressively large. While its base station dirtbag measured capacity of 2.15L is smaller than the advertised claim of 3L, it's still big enough to store a couple of weeks' worth of debris. Its internal dustbin has a capacity of 0.35L, which is actually fairly spacious as far as robot vacuums go, though it'll still need to return to its docking station pretty often.
Since the vacuum's internal water reservoir is built into it and you can't remove it, we can't verify its capacity. The twin water tanks in the multifunction dock each have a max capacity of 2.5L.
The Dreame L10s Ultra's range is limited only by the remaining battery life, but like any robot vacuum, it can't climb or descend stairs.
The Dreame L10s Ultra is heavier than a lot of simpler robot vacuums, like the Shark Matrix Robot, but is pretty lightweight for something this feature-dense, weighing a little over half a pound less than the Roborock Q Revo, which shares a similar feature-set.
The Dreame L10s Ultra has excellent battery performance. It uses a 5200 mAh lithium-ion pack, the same capacity as the pack found in the Roborock Q Revo, but it has a shorter overall runtime. It can run for just under an hour in its 'Turbo' setting. Setting it to the low-power 'Quiet' mode extends its battery life to a little under three hours. This is still plenty of time to deal with lightweight debris but considerably less than the four-hour-plus max runtime from the Roborock.
The Dreame L10s is a feature-packed robot vacuum. Like the Roborock Q Revo, it has an Auto-Mop Lift feature, which lifts the mopping pads when the vacuum is moving on a carpeted surface or when it's returning to its dock, so it doesn't soil the freshly cleaned surface. There are four different suction power modes: the energy-efficient 'Quiet' mode, the default 'Standard' mode, 'Strong,' and 'Turbo,' which is meant for cleaning extremely stubborn debris.
There are various mopping options, too. You can choose between three levels of dampness for its mopping pads: 'Slightly Dry,' 'Moist,' and 'Wet'.
The Dreame features a real-time hazard avoidance system different from the Roborock Q Revo. The Dreame has a structured light sensor and an RGB-color camera, allowing you to use the vacuum as a roving security camera. In contrast, the Roborock has only a structured light sensor.
This vacuum has a three-armed side brush to direct debris into the path of its rubber roller. It also comes with a pair of washable mop cloths that are velcroed onto magnetically mounted rotating base plates.
This vacuum does a good job of cleaning hard floors. Its suction inlet is positioned high enough to easily pass over bulky and medium-sized debris like cereal or rice so that it can suck them up. That said, it does struggle a little bit with fine material sand, especially when it's been piled up against walls or pushed deep into corners.
This vacuum's performance on high-pile carpet is okay. It can clear large and medium-sized debris like cereal or rice pretty efficiently, but it has a hard time with finer debris that's been pressed into carpet fibers and will likely need another run to collect everything.
Note: The vacuum's cliff sensors can trigger on dark-colored surfaces, resulting in navigational issues. We got around this issue in testing by covering the cliff sensors in white gaffer tape, but you likely won't do the same if you plan to use this vacuum at home.
This vacuum delivers inadequate performance on low-pile carpet. It's quite good at dealing with bulky debris, but it may leave behind some smaller solid debris along walls and in corners. Unfortunately, it struggles quite a bit with fine debris that's been pressed into carpet fibers. Check out the Roborock S8 Pro Ultra if you want a robot vacuum that performs better on this surface type.

The Dreame L10s Ultra's suction force isn't very strong, though this isn't unusual for a robot vacuum; its suction inlet is positioned too high above the contact surface to generate a tight seal on bare surfaces, resulting in low suction power measurements. The manufacturer advertises 5300 Pa of suction power, which aligns with similar models like the Roborock Q Revo.
This unit has okay airflow performance for a robot vacuum. It falls a little short of flagship models like the Roborock S8+/S8, but it still isn't bad in this regard.
This vacuum is remarkably quiet in normal operation, and you won't have any trouble hearing nearby conversations even when the vacuum is running in the same room in its 'Standard' setting. However, you can expect it to be a little louder if you have a lot of rugs and carpeted floors or simply need to use a higher power level: noise levels can reach as high as 68.8 dBA when it's set to its 'Turbo' suction mode. In contrast, noise levels drop to as little as 58.1 dBA when the vacuum is in its low-power 'Quiet' setting on bare floors. Its multi-function dock produces a peak volume of 70.2 dBA during the self-empty process, which, while louder than the vacuum, is still far from unbearable.
The Dreame L10s Ultra does a great job of maneuvering itself. Its LIDAR sensor maps out rooms quickly, but while it's quick to clean and pretty thorough, it occasionally moves in a sporadic, unpredictable fashion. It's compact enough to easily clean under most couches, chairs, and tables. Its front-facing camera does a reasonable job of identifying obstacles that the vacuum will avoid and will even take pictures that you can review later. This system isn't fool-proof, however; in testing, the L10s correctly identified a power cord as an object to be avoided and kept away from it, only to return later to the same spot and get stuck. The same issue can occur for thicker shag-pile rugs.
This vacuum does a poor job of sealing in fine particles. Fine allergens bypass its exhaust filter and are blown straight out of its exhaust port and LIDAR sensor.
This vacuum has poor crack-cleaning performance. It struggles with drawing up fine debris wedged deep within crevices, though at the very least, its side brush doesn't fling much debris outwards. Running a second pass in the 'Turbo' suction mode makes little to no difference in terms of performance in this regard, with the final results of said test seen here.
This vacuum's stain-clearing performance is decent with the mop dampness level set to 'Wet,' the mop mode set to 'Highest,' and with detergent poured into the clean water tank. However, a single pass just isn't enough to scrub away a dried-on stain, though a second pass does really help, as seen here.
Running a mopping cycle without detergent results in significantly worse stain-cleaning performance. You can see the vacuum mopping with just water here, and the aftermath of that test here.
After the vacuum has finished mopping, it'll park at the multifunction dock, where the pads press themselves into the textured washboard filled with water to dislodge any stuck-on debris before being dried with a flow of warm air. You can see how the pads looked before the automatic clean cycle here, and after the clean cycle here. This process does dirty the dock's washboard, as seen here.
The Dreame L10s Ultra has a broad array of physical automation features. Most obviously, there's the multifunction dock, which empties its dustbin, refills its water tank, and washes and dries its mopping pads.
Overall functionality is limited without using the app. You can use the buttons on top of the vacuum to have it start a general-purpose cleaning cycle, spot-clean its immediate area, or send it back to its dock.
The Dreamehome companion app is very feature-rich. You can see a quick overview of the interface and features here.
Once the vacuum has generated a map of your home, you can access that through the app to set up no-go zones and virtual barriers, set up different cleaning areas and split rooms, label areas, and set floor materials so that you can set up fully custom cleaning modes for different rooms. Like most models in this price bracket, the Dreame supports multi-floor mapping, with memory for four different floors.
Like the Roborock S7 MaxV, you can use the Dreame as a roving security camera by looking through its front-facing camera. It also has a built-in mic and speakers, so you can talk to others through the vacuum and hear what they're saying.
You can use the app to enable 'Carpet' mode, which allows for automatic power adjustment on carpeted floors, 'Carpet Avoidance,' 'Low-Collision' mode, which prioritizes avoiding contact with walls and furniture at the expense of lower-precision scanning in tight spots, and 'Pet' mode, which boosts object detection performance for avoiding hazards like pet waste, but may degrade overall coverage.
