Dreame L10s Ultra Vacuum Review

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.

• Dirt compartment: Since this vacuum has a self-emptying function, in which debris is sucked from its internal dustbin into a dirtbag inside its dock, you actually won't have to empty its dustbin manually all that often. That said, the manufacturer does recommend rinsing it under water every two weeks. Thankfully, removing it is easy. All you need to do is lift the top cover of the vacuum and pull it free.
• Base station dirtbag: The base station dirtbag is held in place with a plastic collar, so it's pretty easy to slide out after you've opened the dock's dirtbag compartment door. The bag self-seals after you've removed it, preventing dust and debris from spilling out during disposal. It has an advertised capacity of six to eight weeks' worth of debris, though you'll likely find it less than that depending on whether or not you have floors that gather a lot of dirt, dust, and pet hair.
• Vacuum filter: The filter is held into a slot at the top of the vacuum's dirt compartment and can be un-clipped very easily. You should pull out any stuck-on solid debris whenever necessary, and the manufacturer recommends that you rinse it under water every two weeks.
• Brushroll: After popping off the brush guard, you can essentially just pull the brushroll out of its slot. The roller is somewhat tangle-prone, especially compared to alternatives like the Roborock S8, which features twin rubber rollers. Thankfully, this unit does come with a cleaning tool that allows you to cut away hair that's tangled in the roller. You should clean the roller twice a week.
• Side brush: You can just pull the side brush out of its slot. You should clear away any stuck-on debris every two weeks, either by hand or with the provided cleaning tool.
• Omni-directional wheel: You should remove the front wheel and rinse it every month to clear out any dirt and grime.
• Sensors/Charging contacts: You'll have to wipe off the RGB camera cover at the front of the vacuum, the metal charging contacts underneath the vacuum, and at the front of the dock, and the auto-empty inlet with a clean dry cloth once a month.

The Dreame L10s Ultra's mopping systems also have their own fair share of required upkeep.

• Mop pads: The mopping pads are velcroed onto their base plates, which in turn are attached to twin magnetic pegs under the vacuum. You can simply pull these base plates off. No specific maintenance interval is given, but since this unit's multi-function dock washes its pads with warm water and dries the mop pads automatically, you won't have to clean them yourself all that often.
• Multi-function dock clean water tank: You can simply lift the clean water tank upwards from its slot in the dock. You should refill this tank as necessary. The manufacturer recommends rinsing it out every two weeks.
• Multi-function dock dirty water tank: As with the clean water tank, you can just lift the compartment from its slot. You should empty it and clean it every two weeks with the provided cleaning brush.
• Multi-function dock washboard/Base plate: You can slide out the base plate from the base of the station. You should rinse it with cool water whenever necessary.

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.

• Brushroll: You'll need to replace the brushroll after 300 hours of use or every six to 12 months. Replacements can be purchased here.
• Side brush: The side brush has a service life of 200 hours or approximately three to six months of use. You can buy a two-pack of replacements from the company's website here.
• Filter: The filter needs replacing following 150 hours, according to the maintenance tab of the companion app, or every three to six months, according to the manual. You can buy replacements in packs of two here.
• Mop pads: You should replace the mop pads every 80 hours or one to three months. Replacements can be purchased here.
• Multi-function dock dirtbag: The dirtbag has an advertised capacity of 2.7L, enough for seven weeks worth of debris. Replacements can be purchased here.

You can also purchase an Accessory Kit bundle, which comes with:

• 2x Dirtbags
• 2x Side brushes
• 1x Brushroll
• 2x Filters
• 6x Mop pads

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.

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 does a poor job of dealing with pet hair on low-pile carpet. While it clears away lighter strands that are barely resting on carpet fibers, some hair gets stuck on the brushroll and is left to drag along the floor, where it can get stuck again.

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.

This vacuum isn't designed to deal with liquid spills. It can clear away small spills by soaking them away with its mopping pads, but having the vacuum suck up liquid is likely to damage it.

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.
