This article is an overview of all Roborock models – A bird’s eye view of how Roborock clustered its products and which one is the best.
I’ve spent many days testing these products and gathering data, and this article is a culmination of that hard work.
We’ll also look into the similarities, differences, nuances, and suggestions on which model may suit your needs.
[toc]Roborock Comparison Chart
What’s the difference between the Roborock C10, E25. E35, E4, S4, S4 MaxV, S5, S5 Max, S6, S6. Pure, S6 MaxV, and S7?
This section will highlight the different Roborock robot vacuums across various price levels – from entry-level options (below $300) to high-end alternatives ($400++).
Entry-Level
These options are the least expensive in Roborock’s lineup (under $300).
The E25, E35, and E4 use the same navigation type – dual gyroscopes and an optical sensor Roborock call the “Optic Eye.”
This technology is similar to Roomba E5, enabling manufacturers to bring the price down.
It moves in straight lines, but it can’t save maps since it doesn’t have LIDAR (Laser Distance Sensor) or SLAM.
Some variants have been discontinued, notably the C10, E25, and E35.
But the latter two are still available in online stores like Amazon.
The latest E-series available are the E4 and E5. I’ve only tested the Roborock E4 of the models here, but it has the same navigation as the others listed here.

Mid-Priced Options
Next in Roborock’s hierarchy are the mid-priced options ($300 – $500), and currently, there are three options – the S4, S4 Max, and S5.
The S4 and S4 Max are recent additions. These models utilize the same LIDAR and SLAM combo as the S5 Max without the mopping functionality.
Since it doesn’t have a water tank, Roborock could lower the cost.
All these models have LIDAR, VSLAM and can save maps (up to 4 levels).
I’d say these are some of the best value Roborock products available.
Users will have access to features only seen in higher-end robots, such as no-go zones and selective room cleaning.
Unfortunately, first-gen Roborock models like the S5 (discontinued) won’t have access to these features. So you’ll have to go with a newer variant like the S4 Max.

High-End Options
Lastly, we’ll look into Roborock’s premium alternatives or options above $500. These include the S5 Max, S6, S6 Pure, and S6 MaxV.
The S5 Max was the first to have the electronic water tank, making it a better mopping robot than older Roborock models with the gravity tank.
I’ve tested it extensively on dried stains, and it left very minimal streaks. Outside the Viomi V3 or Xiaomi Mop P, the S5 Max is the best robot vacuum/mop combo.
Update: With the release of the Roborock S7, I wouldn’t consider the S5 Max the best in class robot mop hybrid. The S7 has surpassed it thanks to the vibrating mopping module.
The S6 and S6 Pure are the same robots with minor differences. First, the S6 Pure has an infrared wall sensor, while the S6 utilizes a laser wall sensor. Lastly, the S6 Pure has a larger water tank (180 ml vs. 140).
Recently, Roborock unveiled the S7 – their latest product with sonic technology.
This means the robot not only mops, but it also has an agitation element absent previously.
It also has many other enhancements like intelligent mop lifting and a mop-only option where the vacuum motor shuts off to extend the range further.

Similarities between Roborock robots
First, I’ll enumerate the similarities between Roborock options.
1. Shape
All Roborock robot vacuums have a round frame, from the entry-level C10 to the flagship S6 MaxV.
2. Single side brush
Next similarity – all have a single side brush. However, the newer releases like the S5 Max, S6 Pure, and E4 use the rubber version, which I like a lot for durability reasons.
Earlier models like the S5 or the S6 use the older bristle-tip design, something prone to wear.
3. Combo brush
If you look at the graphic above, all Roborock products use a combo brush with bristles and rubber blades. It’s a staple in their design from the beginning when Roborock and Xiaomi were one.
4. App Compatibility
One feature I like with Roborock is the app. All the variants here are compatible with the Xiaomi Home App, but only select models will work with the Roborock app: S6, S4, S4 Max, S5 Max, S6 Pure, and S6 MaxV.
Regardless of which app you choose, both have similar functionality. One advantage the Xiaomi app has is the option to name rooms. It’s a feature you can use in conjunction with Alexa. So you can say, “Roborock, please clean the living room,” something not possible if you’re using the Roborock app.
5. Battery
All options utilize the 5,200 mAh Li-ion battery except the E2 (or E25) and C10. Run time will vary between the E and S series since the latter has the larger motor.
Differences between Rororock options
1. Navigation sensor
The lower-end E-series robots utilize a combination of gyroscopes and an optical sensor for tracking location. This enables it to traverse in straight lines.
However, it won’t save maps since it lacks the Laser Distance Sensor and the SLAM algorithm.
2. Dustbin capacity
While all Roborock products have the same top-mounted dustbin, the volume will vary.
For instance, the E-series robots use an enormous 640-ml container, which is possible because the LIDAR is out of the way.
3. Run Time
The range will vary between the lower-end E-Series and more premium S-Series robots. For example, the E4 will last for up to 200 minutes on a single charge. The S5 Max, with its higher wattage motor, runs 20 minutes less.
Roomba Model | Run Time |
---|---|
Roborock C10 | 100 mins. |
Roborock E25 | 100 mins. |
Roborock E35 | 200 mins. |
Roborock E4 | 200 mins. |
Roborock S4 | 180 mins. |
Roborock S4 Max | 180 mins. |
Roborock S5 | 180 mins. |
Roborock S5 Max | 180 mins. |
Roborock S6 | 180 mins. |
Roborock S6 Pure | 180 mins. |
Roborock S6 MaxV | 180 mins. |
These are Roborock’s claims in the quiet setting.
However, run time shouldn’t be an issue for S-Series robots like the S5 Max or S6 MaxV since it has recharge and resume.
4. App Features
Not much difference, but it will vary depending on the variant you select. Low-end options like the E25, E35, and E4 can’t save any map.
So users won’t have access to advanced features such as a no-go zone or virtual wall. But it retains unlimited daily scheduling, which is absent in more expensive robots like the Roomba 980.
Only premium models (S5 Max, S6 Pure, and S6 MaxV) are these features unlocked. With the S5 Max and S6 MaxV, consumers will enjoy the benefits of the no-go zones, no-mop zones, virtual walls, and selective room cleaning.
The no-go and no-mop zones are identical in functionality, where the robot will avoid a square or rectangular zone.
Auto empty dock
Roborock recently released its first auto empty dock for the Roborock S7 to compete with a growing list of brands that have added this feature to their products.
Its twin-cylinder design is unique as other brands utilize only one cylinder, usually to house the bag.
This design isn’t just for show but has a practical purpose. The first barrel house the two filters, while the bag is inside the second barrel.
Yes, you hear that right; this base station has filters to complement the bag. There’s also a bagless version for this dock, but I’m not sure if it’ll be released to the US market.
It could be a reason why it has two additional filters to accommodate the bagless auto-empty dock.
Roborock E25
Pros
- It has efficient navigation minus the premium cost.
- Excellent cleaning dynamics.
- Great at surface dirt on hard floors or carpet.
- Large dustbin.
Cons
- Not great at mopping.
- It doesn’t come with a virtual wall or barrier.
The E25 was Roborock’s first robot with dual gyroscopes and an optical sensor. There was no other robot vacuum in its price range during its release.
It navigates like a high-end robot (i.e., Roomba 980 and Roborock S5 Max), making it more efficient than standard navigating robots. The only other robot vacuum I know with an optical sensor is the costlier Roomba I3.
However, it won’t be as thorough as the S-Series, which can go over the area up to three times.
Cleaning performance is excellent for a budget robot vacuum. It has the same high-quality brush found in the more premium options like the S5 Max.
Airflow (17 CFM) is also excellent, nearly matching the Roomba 980 (19.74 CFM).
The E25 also comes with a gravity mop, but don’t expect too much. It won’t do much with dried stains, and it lacks the back-and-forth motion of a Braava or Viomi V3.
Overall the E25 is an excellent budget option if you don’t want to spend more than $300 on a robot vacuum.
Roborock E35
Pros
- Slightly better at deep cleaning than the E25 (77% vs. 74%).
- Efficient navigation.
- It has a Large (640 ml.) dustbin.
- Excellent at surface cleaning.
Cons
- The mop can only clean light stains but won’t replace a traditional mop.
- It lacks containment features like a virtual wall.
After the E25 is the beefed-up E35, Roborock claims this model has more suction (2,000 vs. 1,800 Pascals).
But airflow tests reveal that the E25 and E35 are equal (17 CFM) – the same number as the S5 Max.
Regardless, the E35 provides the same clean pick-up in all Roborock products, thanks to its high-quality brush roll.
It has a spring-loaded system, automatically adjusting to the height of the surface it’s cleaning.
You’ll find this feature in premium brands like Roomba and Neato, which shows that Roborock pays attention to the little details.
Deep cleaning is excellent (77%), surprisingly better than the newer E4.
The E35 also comes with a mopping pad, but like the E25, it will only work with light stains.
Overall, the E35 is another excellent budget Roborock option, a little more expensive than the E25 but cleans embedded dirt a tad better based on tests.
Roborock E4
Pros
- Budget robot vacuum (under $300) with smart navigation.
- It has excellent airflow with over 20 CFM.
- The dustbin has a good volume (0.64 liters).
- Excellent at surface debris pick up on hard floors and carpet.
- It’s one of the least expensive options with recharge and resume.
Cons
- It’s only average at deep cleaning (69.83%).
- Not very good at cleaning the edges.
- It can’t save maps.
The E4 is Roborock’s latest offering in its E-Series line and one of its least expensive options. Like their predecessors, the E25 and E rely on two gyroscopes and an optical sensor for navigation.
Roborock has revamped the design of the E4, following the S6 Pure’s lead with sharper lines.
The large 5,200 mAh Li-ion battery enables the E4 to run for up to 200 minutes. People looking for a budget robot vacuum capable of cleaning large areas with efficiency should consider the E4.
Even without the map saving feature, the E4 is cheap. It’s in the range of the Roomba 675 and 690 but with more intelligent navigation.
Unfortunately, it won’t clean embedded dirt as well. So it’s a trade-off you should consider.
Roborock S4 and S4 Max
Pros
- Best value for money, Roborock.
- Decent at cleaning embedded dirt with an 80.2% score.
- It has very efficient navigation with LIDAR and SLAM.
- The S4 Max has a bigger dustbin capacity than the S4 (460 vs. 420 ml.)
- Not as noisy as a Roomba.
- It can save up to 4 map levels.
Cons
- No mopping option.
Next, we’ll examine the Roborock S4 (discontinued) and S4 Max (see photo above). I put these two in a cluster because of the similarities. These two are the only options in Roborock’s S-Series line without a mop attachment.
Both variants use the same combo brush and all-rubber side brush. It’s an S5 Max without a mop.
Differences between the Roborock S4 and S4 Max
- Dust bin: The S4 Max has a slightly larger dustbin at 0.46 liters versus the S4’s 0.42-liter capacity.
- Brush roll placement: The older S4’s primary brush sits closer to the front, whereas the S4 Max’s is close to the middle.
- Airflow: The S4 Max has more airflow with over 22 CFM. In comparison, the S4 is at 19 CFM.
- Design: Another difference is design. The S4 Max has a matte black finish, which I like better than the S4’s glossy design. Also, the S4 Max adapts the button layout of the S5 Max.
It’s a good cheaper alternative if you want the same functionality as the S5 Max but without the mopping feature.
The S4 is also a good alternative since it’s the cheapest Roborock S-Series option. You’ll get all the bells and whistles of the S5 Max without having to pay a premium.
Roborock S5 Max
Pros
- It’s one of the best robot vacuum/mops for mopping floors, next to the Viomi V3.
- The best option I’ve tested at deep cleaning carpet.
- A large water tank covers a lot of ground and is very efficient.
- It has app features not available in other brands like the Roomba 980.
Cons
- Premium price tag.
The S5 Max is one of Amazon’s more popular options at its price range, with good reason.
It’s one of the first (if not the first) robot vacuum to utilize a proper electronic water tank.
I said true because there are companies in the past making this claim but failed to deliver. The ILIFE V7S Pro comes to mind.
You can control how much water flows through the pad using the app.
Not once was the pad drenched, or I found a puddle of water underneath.
Delivery was precise, and there were minimal streaks afterward. It will work best on dried stains where the pad does its best work.
Unfortunately, it doesn’t have the back and forth motion of the Viomi V3 (check comparison here). Still, it’s very efficient at water usage, and the 290 ml capacity will cover a lot of ground.
The S5 Max is Roborock’s best option for people looking for a robot vacuum that can vacuum and mop equally well.
Roborock S6
Pros
- The 32-bit quad-core processor makes it very efficient at traversing.
- Excellent at surface debris pick up.
- Users will have access to high-end app features like no-go zones and invisible walls.
- Decent mopping performance.
Cons
- Premium cost.
- No electronic water tank.
- Small dust bin.
Before the S5 Max, the S6 was Roborock’s flagship. The upgrades aren’t as evident on the surface. Most of it is with the navigation, which comes with a 32-bit quad-core processor.
This enhancement makes the S6 more efficient with its navigation.
The tests reveal the S6 is 25% faster than the S5 Max and the
However, the S6 has less airflow than the S5 or S5 Max with 15 CFM.
It won’t affect it as much with surface cleaning as it picks up debris cleanly on hard floors and carpets.
But deep cleaning will be average as it only picks up 69% of embedded sand on mid-pile carpet.
The Roborock S6 is a compelling option, more efficient than the S5, but too expensive for me.
Roborock S6 Pure
Pros
- Cheaper than the Roborock S6.
- Efficient navigation.
- It has a bigger water tank versus the S6.
- Slightly better airflow than the S6.
- Not very noisy.
Cons
- Not as good as the S5 Max with mopping.
- Smallish dustbin.
The S6 Pure is the newer version of the S6. Strangely, it’s less expensive, with downgrades to the wall sensor and a smaller dustbin.
Aside from those downgrades, the S6 and S6 Pure are virtually the same robots with the same motor and battery.
It has slightly better airflow than the S6 (18 vs. 15 CFM), so it deep cleans better (72% vs. 69%).
Both will have the same efficient navigation and will do well even in tight spaces.
Users have access to all the advanced app features – no-go zones, invisible walls, selective room cleaning, etc.
I would suggest using the Xiaomi Home app because it provides the option to name rooms.
Between the S6 and S6 Pure, I’d go with the latter since it has more airflow and a slightly bigger water tank but a smaller dust container. The downgrades don’t affect its cleaning performance.
Roborock S6 MaxV
Pros
- Better obstacle avoidance.
- The electronic water tank works as well as the S5 Max.
- It has a slightly bigger water tank than the S5 Max.
- Above-average at deep cleaning (77%).
Cons
- Quite expensive.
- It has less airflow than the S5 Max.
The former flagship option of Roborock is the S6 MaxV with the front-mounted camera.
This addition enables the S6 MaxV to “see” and avoid obstacles. I’ve done a lot of experiments to see how well it avoids objects with mixed results.
Roborock will roll out firmware updates to improve how the camera detects objects. It does well at avoiding larger stuff like shoes and bags.
I tried placing a weighing scale, and it was able to avoid it.
However, there were instances where it went over it.
Wires are also a mixed bag. It can avoid coiled-up wires, but the camera no longer “sees” it once you stretch it out, and the robot’s side brush will tangle.
One issue with the current technology is the blindspots. If the obstacle falls into those areas, the robot will not avoid the object.
So the technology isn’t perfect, but Roborock is working hard to fine-tune the rough edges.
The latest update adds a camera view, so users can see what the robot sees.
One significant roadblock is the price. The S6 MaxV is expensive for a robot vacuum without a second vacuum in the dock.
I would only recommend this robot if you need the obstacle avoidance feature because the S5 Max will provide the same features at a lower cost.
Another alternative with a front camera is the Ecovacs T8 – click here to learn more about the similarities and differences.
Roborock S7
Pros
- Vibrating mopping pad adds an agitation element missing previously
- Removes large quantities of dried stains in a single run
- New brush roll picks up surface debris extremely well
- Navigation upgrades like crisscross pattern offer better thoroughness
- Excellent at avoiding obstacles, despite not having any front camera
- Decent at deep cleaning dirt
- It has an optional auto empty dock that empties the robot’s dustbin for you.
Cons
- Noisy at close to 70 decibels at the max setting
- It doesn’t deep clean as well as the S5 Max, but better than the S6 MaxV
The lack of agitation is one issue with current robot vacuum/mop hybrids. When I say hybrid, I’m talking about the likes of the Roborock S5 Max, Ecovacs T8 AIVI, and Dreame D9 – smart robot vacuums with an electronic water tank.
The Roborock S7 aims to solve by adding agitation to the equation.
It’s one of the first robot vacuums I’ve seen with a vibrating mopping pad called VibraRise.
Related: Roborock S7 vs. S6 MaxV vs. S5 Max – Is it time to upgrade?
The first upgrade is the vibrating mopping pad that adds a scrubbing element previously missing. And the next upgrade is the Rise feature, where the pad lifts when the robot detects carpet.
These enhancements aim to improve mopping performance and user experience without removing the pad for hybrid tasks.
I’ve tested these extensively on various stains like red wine, grape juice, and tomato juice, and the results were encouraging.
The vibrating feature helps immensely in tackling stains. It did an excellent job at cleaning large red wine stains without having to do additional runs.
It did leave a stickier residue when I tested it on juice stains since these contain sugar. But after a second “clean up” run, it tackled it well.
Consumers also can purchase the S7’s auto empty dock as an add-on if they need the self-emptying feature.
The US market gets the bagged version, while the EU consumers get the bagless version if the rumblings I hear are accurate.
One unique feature about it is the additional filtration from the two filters housed in the left cylinder that provides an extra layer of protection from microscopic dust (up to 0.3 microns).
The port placement is another unique element, as it uses the robot’s main brush inlet to suck contents out.
I’ve tested it extensively, and it’s a solid design, capable of emptying debris inside the bin and filter.
Roborock S7 MaxV Ultra
Pros
- Self-washing and self-emptying base station
- Better obstacle avoidance than the S6 MaxV
- New 3D map feature gives consumers a different map perspective
- Efficient navigation and cleaning performance
- Easy access to the water tanks and bag
Cons
- Bulky base station
- Astronomical cost
The S7 MaxV Ultra is currently Roborock’s latest option with some critical upgrades, improving usability and autonomy.
The redesigned base station is at the forefront of these enhancements that incorporate the pad washing feature with the auto-empty convenience.
Also, Roborock tweaked its Reactive AI system, adding laser sensors and LED to enhance its obstacle avoidance capabilities.
Other new features include the new 3D and Matrix map options, providing consumers a 3D perspective in viewing the maps.
The Matrix option is only available on iOS devices, but not on Android phones.
This robot retains the same navigational efficiency and cleaning performance as the S7+ since it uses the same motor.
But it offers better mopping autonomy with the pad washing feature.
Cleaning Comparison
Roomba Model | Overall | Hard Floors (Surface Test) | Sand on Hard Floor | Carpet (Surface Test) | Deep Cleaning |
---|---|---|---|---|---|
E4 | 91.05% | 99.8% | 99.4% | 97% | 69.83% |
S4 Max | 94.45% | 99.7% | 99.9% | 98% | 80.2% |
S5 Max | 94.68% | 100% | 99.8% | 99.31% | 84.75% |
S6 Pure | 92.54% | 99.61% | 99.85% | 98.72% | 72% |
S6 MaxV | 93.9% | 99.75% | 99.7% | 98.5% | 77.65% |
Q5+ | 93.26% | 99.95% | 99.9% | 97.5% | 75.7% |

S7 MaxV Ultra | 94.11% | 99.95% | 99.6% | 98.97% | 77.95% |
There isn’t much variance with surface debris pick-up as all these options got in the high 90s on all surface debris experiments.
However, there’s a variance in deep cleaning embedded sand as the S5 Max, and S4 Max are the only options above 80%.
The S7+ and S7 MaxV Ultra are the next best options at 78,85% and 77.95%, respectively.

Which Roborock is the best?
Selecting the right Roborock product will depend on your budget, type of floor at home, floor area, and whether or not you need the mopping feature.
The best Roborock, regardless of price, is the S7+, which is their current flagship.
The auto-empty dock that offers hands-free convenience you won’t see in other Roborock variants pushes it to the top.
There’s no need to touch this robot for weeks after setting the scheduled runs.
It’s also the best performing robot mop alternative, thanks to VibraRise, where a vibrating pad makes it more efficient at cleaning stains.
Unfortunately, the auto-empty station can’t clean the pads, so you’ll have to do that task manually.
The astronomical cost is its biggest flaw, and if it’s a deciding factor, then the S5 Max or S4 Max would be excellent value alternatives.
These models offer the best price to performance ratio. For folks who don’t need the mopping feature, go with the S4 Max since it’s cheaper.
One under-the-radar option is the S6 Pure. It’s cheaper than the S5 Max and offers similar vacuuming results with worse cleaning performance.
If it falls below $400, it is an excellent deal for the navigational and app features.
Lastly, the E-series (E4 and E5) are options for budget-conscious folks looking for a cheap but efficient navigating robot.
Roborock Maintenance
Like with all robot vacuums, Roborock products need proper upkeep to function at their best.
I’ll enumerate the different parts you’ll need to clean regularly.
- Main brush: Roborock says its brush roll has an anti-tangle system but doesn’t mean maintenance-free. You’ll need to regularly check it for any debris buildup (particularly hair).
- Side brush: Remove the screw and remove any hair wrapping around the arms or underneath. Any debris accumulation will cause more friction and could burn out the motor.
- Caster wheel: This is the smaller wheel responsible for steering the robot. Grab a clean microfiber towel to remove dirt sticking to it.
- Side wheels: These are the main rubber wheels on either side of the main brush. Again, use a clean towel to clean the threads and sides.
- Dustbin and filter: Empty the dust receptacle after every cleaning cycle. Use a handheld with a brush attachment to remove any accumulation of dirt on the HEPA filter. Roborock says the filter is washable, but I’d discourage water use since it will degrade the filter sheet.
Parts like the battery aren’t as abundant as a Roomba, but you can try searching for them on online stores like AliExpress or eBay.
