Roborock Comparison

This article will be an overview of all Roborock models – A bird’s eye view of how Roborock clustered its products.

We’ll also look into the similarities, differences, nuances, and some suggestions which model may be suitable for your needs.

Roborock Comparison Chart

What’s the difference between the Roborock C10 vs. E25 vs. E35 vs. E4 vs. S4 vs. S4 MaxV vs. S5 vs. S5 Max vs. S6 vs. S6 Pure vs. S6 MaxV?

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.” It traverses in straight lines, but it can’t save maps since it doesn’t have LIDAR (Laser Distance Sensor) or SLAM.

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 was able to lower the cost.

All these models have LIDAR, SLAM 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.

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.

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).

Similarities between Roborock robots

First, I’ll enumerate the similarities between Roborock options.

1. Shape

Roborock Comparison Shape

All Roborock robot vacuums have a round frame from the entry-level C10 to the flagship S6 MaxV.

2. Single side brush

Roborock side brush comparison

 

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, in my opinion.

3. Combo brush

Roborock main brush roll

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 for 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 does not have 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.

Roborock dustbin

The C10 and E4 dustbin side-by-side. Both have a 0.64-liter capacity.

For instance, the E-series robots use a bigger 640-ml container, which is possible because the LIDAR is out of the way.

Comparison the Roborock S5 and S6 MaxV dustbin

The Roborock S5 (left) and S6 MaxV dustbin (right).

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 ModelRun Time
Roborock C10100 mins.
Roborock E25100 mins.
Roborock E35200 mins.
Roborock E4200 mins.
Roborock S4180 mins.
Roborock S4 Max180 mins.
Roborock S5180 mins.
Roborock S5 Max180 mins.
Roborock S6180 mins.
Roborock S6 Pure180 mins.
Roborock S6 MaxV180 mins.

The run times listed, there 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 the 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 wall, 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.

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. During its release, there was no other robot vacuum at its price range with such.

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 that 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).

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 the E25 and E35 are equal (both have 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

Roborock E4 top view

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.
  • Can’t save maps.

The E4 is Roborock’s latest offering in its E-Series line and one of its least expensive options. Like its predecessors, the E25 and E35, it relies 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 smarter 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

  • 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 look at the Roborock S4 and S4 Max. I put these two in a cluster because of the similarities. Despite the aesthetic differences, there are a lot of similarities.

The only difference based on the spec sheet is the dustbin with the edge going to the S4 Max.

It’s basically an S5 Max without a mop.

If you want the same functionality of the S5 Max but don’t need the mopping feature, it’s a good, cheaper alternative.

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

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 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 fail 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 surface debris pick up.
  • Users will have access to high-end app features like no-go zones and invisible wall.
  • 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, where it 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 Roomba S9 in traversing around small and large rooms.

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

Roborock S6 Pure Top View

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 does have 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 will have access to all the advanced app features – no-go zones, invisible wall, 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

Roborock S6 MaxV top view

Pros

  • Better obstacle avoidance.
  • 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 current 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.

The camera “sees” the shoe and went around it.

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 once you stretch it out, the camera no longer “sees” it, and the robot’s side brush will tangle.

The S6 MaxV avoided the coiled wire.

 

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.

Where can you guy these robots?

You can buy the Roborock robot vacuums on Amazon. Please check the links for more information.

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 for me at the moment is the Roborock S5 Max. It strikes a balance between price, features, and performance. This model is one of the best robot vacuum/mop combos I’ve tested.

The electronic water tank did very well with the mopping tests on dried stains. Having an electronic system helps it dispense water at the proper rate. The results are clean floors with very minimal streaks.

It’s also one of the best options for vacuuming surface and embedded dirt.

For the budget-conscious, it’s the choice between the E35 and E4. I would opt for the cheaper one since both are close in terms of features.

The E4 does have more airflow with the all-rubber side brush, which will hold up better over time.

Roborock Maintenance

Like with all robot vacuums, Roborock products need proper upkeep to function at its best.

I’ll enumerate the different parts you’ll need to clean regularly.

  1. Main brush: Roborock says its brush roll has an anti-tangle system but doesn’t mean maintenance-free. You’ll need to check it for any debris buildup (particularly hair) regularly.
  2. 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.
  3. Caster wheel: This is the smaller wheel responsible for steering the robot. Grab a clean microfiber towel to remove dirt sticking on it.
  4. 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.
  5. 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 it on online stores like AliExpress or eBay.
