These robot vacuum slash mop hybrids have done it all base stations with pad washing and self-emptying features. Making them excellent autonomous options for your mopping and vacuuming needs. 

While these robots are similar in this aspect their designs vary greatly and we'll cut these to determine which is the better option for your needs. 

Robot vacuum technology has matured over the past 10 years and these brands are the Pinnacle of this technology. 

Combining features previously available in different products specifically talking the pad washing and self-emptying features adds an element of autonomy absolutely in other brands, not many brands combine these features. 

Because of the complexity and cost requirements not even big brands like iRobot have this feature. Roborock and Dreame are among the few brands with this combination.

Do-it-all base station

While both have the same versatile do-it-all base stations dirty signs are distinct Roborock's design is unique

Since it has the water tanks and bag lineup in a row while Dreame's version isn't since other brands like Ecovacs use the same framework with two water tanks on the top and the bag in the middle. This alignment makes the Roborock base station-wide consuming more horizontal space while the Dreame space station is taller but with a thinner profile.

Both have a pad washing feature but with different mechanisms for the task. 

Dreame uses a rib contraption where the pad spins to agitate and dislodge debris while Roborock's design is more unique. 

Dreame's design is more common and can be seen in other brands like the Ecovacs X1 and Narwhal T10

The Roborock design it uses stiff bristles and the option to control the agitation speed something absent in the Dreame L10S.

The advantage of the Dreame L10S Ultra design is there's no need to replace the ribbed contraption. It's pretty sturdy and should last the robot's lifetime whereas the bristle brush of rope wrap will eventually wear out. 

However, Dreame's pad washing feature isn't as good since it uses a ribbed component to scrub the pads which don't have the same agitation as the Roborock S7 MaxV piece bristles going from side to side. 

Bag capacity

Another advantage of the Dreame L10S Ultra is it has a larger bag capacity of 3 liters 0.5 liters more than a Roborock S7 MaxV Ultra providing consumers with longer bag replacement intervals. 

And potentially saving more long term.

This is the most significant downside of the horizontal positioning of Roborock water tanks and bags.

Water tank

The Roborock S7 MaxV Ultra has a larger cleaning dirty water tank capacity of 3 and 2.5 liters. Respectively compared to the Dreame is 2.5 and 2.4 container volumes. 

But the Dreame L10S has a slot for the cleaning solution container making disbursement automatic and not a manual process. So the advantage to Dreame in this category both options uses the ram-style dock providing a solid base for the robot to sit during the self-emptying cycle. And preventing alignment issues present in vertical ports another variance is the port size and location. 

The Roborock S7 MaxV Ultra uses the robot's brush roll as the port. Allowing them to use a larger slot enables more debris to flow through a larger space Dreame's spot is behind the robot and noticeably smaller. But equally efficient at emptying debris where the robots dustbin. 

Robot dust bin

Both have the models dustbin with the S7 MaxV having more capacity at 400ml compared to Dreame's 350ml volume. The 50ml variants aren't a lot and for self-inting robot vacuums it shouldn't be a factor. Because of the auto-empty feature.

Brush roll

Another similarity is the bristle's nature of the brush roll with the bladed design with varied orientations. 

Roborocks uses slightly angled straight fins wrapping another roller and Dreame's brush has a v-shape pattern. 

It all surface debris tests despite the lower airflow it made cleaner passes. Even with hard-to-clean items like sand, the S7 MaxV got higher scores. Because it had better brush roll dynamics. Enabling it to funnel more dirt toward the vacuum inlet makes it more efficient.

It also picked up more hair in both 5 and 7-inch experiments. Because again it has a better brush roll design and seals enabling it to pick up a higher percentage. These numbers are backed up by the eye test as there's less hair wrapping on the Roborock S7 MaxV brush roll compared this much by the Dreame L10S

However, deep cleaning results are similar with the Roborock S7 MaxV and Dreame L10S Ultra picking up the same percentage. 

These figures confirm the low airflow nature of these robots. So don't rely on either solely for cleaning carpets.

Navigation

They were both very similar in terms of efficiency meaning how many square meters per minute they could cover. 

But speed isn't everything you also have to consider how much area they actually cleaned during that time.

And the Roborock consistently covered two square meters more than the L10S 33-31. In other words, the Roborock was more persistent and getting harder to reach places than the L10S without sacrificing much in terms of efficiency.

The Roborock S7 MaxV Ultra and Dreame L10S Ultra utilize a slider or laser distance sensor. 

Both will navigate similarly starting the run and vacuuming the edges before moving toward the middle portions.

These robots are efficient with navigating around tight quarters and did well in the coverage test completing a two-pass run in around 20 minutes. Both are efficient at debris pickup during this experiment. 

Map creation is also fast-tracked through the mapping run available in the respective apps. This feature takes advantage of the lighter's 360-degree scanning ability to create maps in a fraction of the time compared to a normal run.

Another similarity is a three Pass Run available through the selective room cleaning and Zone cleaning features. 

Dreame is the brand with this feature adding a layer of thoroughness not available with most other brands. 

Battery efficiency

We now also do a battery life efficiency test by making sure that each of the three runs is done using a different power setting low power max power and what I call best settings which in this case is their second to lowest power setting with the carpet boost on.

And here the Dreamtech L10S was the winner and by a pretty good margin getting an average of 2.3 minutes per battery life percentage point compared to 1.6 minutes on the Roborock.

Obstacle avoidance

Was by conducting four different categories of obstacle avoidance tests with the same objects and both robots did quite well. Though the Roborock had a slightly better score than the Dreamtech.

Mostly because Dreamtech missed one of the smaller novelty pet waste in the test. Though it was able to recognize and avoid others.

These robots use similar sensors for obstacle avoidance a front-facing camera and lasers flanking them. 

One variance are that the S7 MaxV Ultra has an LED below the camera to help illuminate its path helping it see obstacles even in dark areas. 

Roborock added it because the camera doubles as a CCTV something absent in the Dreame L10S. Whether this is a helpful feature will depend on your views on home privacy but that's another topic. 

With obstacle avoidance, I'd give the S7 MaxV the edge because its algorithm is smart enough not to let the robot get too close it was better at avoiding coiled wires and pad feces something that the Dreame L10S struggled with because it gets too close increasing. 

Also, the Roborock app shows photos of the obstacles it sees during the run while the Mi Home app does not but only a graphic of the obstacle type.

Mopping and pad washing

These robots have mopping functionality as a supplement to the vacuuming features. 

Both have to agitate elements making them efficient at cleaning stains but their designs vary. 

The Dreame L10S Ultra uses two spinning pads behind the robot for agitation. While the Roborock S7 MaxV uses a single pad with a vibrating element in the middle. 

Since Dreame uses two spinning pads it doesn't have a water tank inside the robot. It relies on a pre-soaked cycle where the base station disperses water and cleaning solution to the pad to saturate depending on your desired setting. 

Please note that this pre-soak cycle is only available through the mapping-only function while the S7 MaxV doesn't have this limitation since it has an in-robot water tank. 

The Roborock S7 MaxV has the same pre-soak cycle to saturate the pads. But one difference is the orientation its camera faces the base station when docking. And during the pre-soak cycle, the robot comes out of the dock makes a U-turn then backs up toward the base station for the pre-soak cycle. 

Roborock orientation allows access to the dustbin even when a robot is docked which isn't the case with Dreame since you'll need to pull the robot out to open the top door. 

As with the mopping performance, both are efficient at removing stains and getting everything out after the first pass. 

Both have a map-lift feature where their pads are left when it detects carpet it's only a slight lift. So I don't recommend either on plush carpets despite your mopping proficiency one issue with these robot mops. 

It cannot pick up Liquid so I don't recommend using either for mopping large quantities of sticky stains because of the residue accumulation on the surface afterward. It's not specific to these products but to every robot map that cannot pick up liquid.

Mics and value

Let's combine miscellaneous issues and value.

One thing is that the Dreamtech L10S did not seem to lift up its mopping pads when it encountered carpets. So it was getting the carpets wet. But it still wasn't nearly as good as the Roborock at lifting up its mopping pad. 

The Roborock also take a negative score because it got stuck under the couch in the navigation test a couple of times presumably because of its slightly higher profile though that could be fixed in the app using no-go lines. 

App comparison

These robots have smartphone apps helping consumers automate their vacuuming and mopping functionalities making these products autonomous for long stretches. 

Dreame L10S owners will have two options the Dreame Home App or the MiHome App

But I don't recommend the former because it's still in its beta stage and it lacks functionality. So download the MiHome App since it has all the features. 

Both apps have a live map showing the robot's location in real-time. 

The grid lines on the map provide consumers with information on the areas it has cleaned. A 3D map is also available for the Roborock S7 MaxV and Dreame L10S to give consumers a different perspective in viewing the map. 

Based on what I've seen Roborock version is more functional because it's integrated into the main interface. So consumers can easily access this feature.

Another advantage of this integration is another map features like containment integration seamlessly. Dreame is 3D map integration is clunkier with no added benefit rather than just being there. As I've said earlier these apps have a mapping run to Fast Track the map creation process. Since the robot doesn't have to go through every nook and cranny. 

Both apps have a map-saving feature with the option to save up to four levels.

And this feature unlocks other benefits like containment selective room cleaning zone cleaning and more. The containment features of these robots are similar both have access to invisible walls and no-go zones. Invisible wall enables consumers to set up virtual walls through the app. 

One aspect I like about a virtual wall is the option to draw diagonal lines. Helping users block off more areas increasing customization options. 

No goal zones allow consumers to draw boxes or rectangles to prevent a robot from entering these areas. 

Both have a criss-cross pattern. Available only in the selected room cleaning and zone-cleaning features. 

A battery pass run is also available if the extra pass is needed for more thorough cleaning. Consumers can also adjust the power and mop settings through the app. However, there will be variances because of the design differences. 

The Roborock App doesn't have a pad saturation setting like Dreame to simplify the interface since it has an in-robot water tank. 

Folks can adjust the scrub intensity and navigation settings accordingly.

Both have four power settings but there isn't much variance in the airflow numbers in the low and max settings as these robots rely mostly on agitation to pick up debris. So I'd keep it in the higher settings. Again for the best results. 

Features and specs

These two robot vacuums have just above every feature that a robot vacuum can have. 

They both have:

  • electric mop systems 
  • recognize carpets 
  • can lift up their mopping pads
  • LiDAR
  • front-mounted obstacle avoidance sensors
  • auto-empty docks

So that you can vacuum and mop in the same run which is incredibly useful. 

They both use LiDAR for mapping and navigation. 

But they also both have front-mounted obstacle avoidance sensors. That helps them to avoid objects that other robot vacuums miss. 

They both have auto-empty docks that not only evacuate their dust bends automatically but also wash their mop pads and refill their mop tanks. 

Performance

This is where we test things like their power and pick-up ability in the studio and again we found them to be fairly evenly matched. 

They had nearly identical suction scores as well as similar airflow scores though the Dreamtech was a bit more there on the crevice pickup test

The Roborock did much better than the Dreamtech probably because of its new floating brush design that helps the brush conform to floors better. 

And while they were both significantly above average with the carpet deep clean test where we see how good they are at picking up deeply embedded debris in carpets the Dreamtech L10S did do better than the Roborock there. 

While I don't give them scores for their pickup ability I found them both to be great at picking up debris of all shapes and sizes on both hard floors and carpets. Though I did feel like the Roborock was better at picking up fine debris on hard floors than the L10 though it was a minor difference though they use different methods to mop floors. 

For example, the Dreametech L10S uses a spinning brush system whereas the Roborock uses a vibrating mop pad system. 

Other aspects to consider

The Dreame L10S is the quieter option across the board despite having more airflow. 

Only maxing at less than 64 dB compared to the S7 Max series output of over 70 decibels. 

The Dreame L10S will run longer at 210 minutes at the lowest setting. 30 minutes more than the Roborock S7 MaxV despite using the same 5200 mAh lithium-ion battery. But a 30-minute disparity is negligible since this robot is highly efficient plus it has the recharge and resume feature that negates any discrepancy. 

Also, map creation will be done quickly thanks to the mapping run that completes a task in a fraction of the time compared to a traditional run. 

Overall despite some feature shortcomings, the Dreame L10S Ultra held up well against the Roborock S7 MaxV Ultra.

Yes, Roborock got a higher percentage in the cleaning experiments but the difference isn't that significant to be a red flag. 

Both were efficient with navigation and completed the two-pass run time in around 20 minutes picking up nearly everything. So these are excellent options even in large homes where proficient navigation is critical even with the design variations. 

Both are equally good at mopping stains and getting everything out after one pass.

So either of these robots would be a great buy but the Roborock S7 MaxV Ultra still remains the king in my opinion at least for now.

But the Roborock S7 MaxV is much better at optical avoidance with its more advanced algorithm not allowing the robot to get too close it's much better at avoiding pet phases and wires based on tests. Besides obstacle avoidance pad washing and service debris cleaning. 

These robots are closed in other facets so the question is can these advantages negate the price differences of these robots answering that question will determine which option you select.
