Roborock S5 vs S6 Side-By-Side Detailed Comparison

By Natalie Red·Updated: May 21, 2020· 12 min read

Recently, Roborock has launched a new robot vacuum cleaner called Roborock S6. It has a very similar appearance to the previous S5 model, however, there are a few important improvements that makes the S6 smarter, quieter, more efficient and faster. It also got some advanced app features such as smart room recognition, separate rooms cleaning and scheduling, ability to store up to 3 maps.

Update March 15, 2020: The Roborock S5 received a firmware and software update and now it has the same smart features as the S6. I updated the comparison.

Is it worth to buy more expensive Roborock S6 or better to go with more affordable but still powerful Roborock S5? Let's figure out.

The design of the Roborock S5 and Roborock S6

We had a chance to review the Roborock S55 and test the Roborock S6 and have something to say about each model.

With all the improvements, let's look at the differences between the Roborock S5 and Roborock S6. Is there any reason to buy the latest model?

What the Roborock S5 and S6 have in common?

The newest Roborock S6 and S5 share a lot. If you are already familiar with the S5 model, I would recommend going to the section with differences. They both are efficient, provide excellent cleaning performance, smart and are more or less affordable, at least they have a lower price tag than other flagship models with similar features.  Let's get into details, what features they share.

LDS-based intelligent navigation system

Both models have a «head» where the LDS (laser distance sensor or lidar) is hidden. It scans the surroundings and with the help of a powerful processor and SLAM algorithms creates a detailed house map (layout). Thanks to this technology, the robot always knows its location, where it has already cleaned and where needs to clean. Also, it reduces cleaning time by building the most efficient z-shaped path and preventing the robot to go over the same spots twice.

Unlike robots that don't have mapping and randomly move around until the battery is out of charge, the Roborock navigates efficiently. It moves back-and-forth in straight lines methodically covering the cleaning area based on the map it created. The robot is equipped with a bunch of sensors that prevent bumping into things, falling and keep it at a distance of 10 mm from walls and furniture.

Because of mapping, the robot knows where your furniture is and slows down when recognizes one. The Roborock S4, S5, and S6 are the most gentle robot vacuums we have tested, they never bump harshly and overall are safe for furniture. They are even able to identify some chromium chair legs.

Roborock S4, S5, and S6 robot vacuums are the most efficient cleaners in the industry.

App Features

The Mi Home app allows you to watch how the robot builds a map and works in real-time, switching between cleaning modes, start/stop the machine, schedule it to work at a specific time, etc. Keep in mind, the Roborock S6 also supports the Roborock app.

Digital blockers. If there is a room that might not be ready for cleaning or a zone where you have cords, etc., you can set an unlimited amount of digital blocked areas and no-go lines. Once you have done it, the robot would not cross it. You can create a zone by drawing a rectangle or set the tape (no-go line) on a place you don't want the robot to cross.

Zoned cleaning. Let's pretend you need the robot to clean a high-traffic area, some specific room or a part of your house. For these needs, there is a zone cleanup feature. Draw a rectangle on the map to make the vacuum clean within it.

Real-time tracking. You can track how the robot builds a map and cleans your house in real-time.

Manually control it like a radio car. If you need the device to go to a specific spot, you can use the app remote control and manage its movements by sending it where you want to. Also, with the «Target Point» option you can tap on the map, and the robot will go to that place. Much easier than using the remote control.

Impressive performance

Both Roborock models have a powerful motor that delivers 2,000 Pa of suction power. It is one of the strongest suctions in the industry; only a few other robot vacuums have comparable suction power.

Also, the Roborock can climb an obstacle up to 20 mm tall. Carpets that are no thicker than 20 mm is not an issue for the S6 and S5.

The Roborock has sensors that can recognize carpet flooring. Once the vacuum is on carpet, its suction boosted to max level automatically providing deeper cleaning.

The Roborock identifies carpetted surface ensuring deeper cleaning on your carpets

Strong suction power, excellent climbing ability, and carpet boost work together ensuring outstanding cleaning performance on a carpeted surface. The vacuum is able to pick up pet hair, so if you have a dog or cat, the Roborock is ideal for you.

Wet Mopping

The Roborock S5 and S6 come with a water container and a microfiber mop. The newest model has disposable wipes as well.

Mopping helps with keeping bare floor clean without doing it manually. For sure, it does not handle stubborn stains, but it is a useful feature to have. If you run the cleaner a few times per week, it will decrease the need of mopping manually.

The Roborock S6 has a new water tank that has a switch to adjust the level of water dripping.

To start - fill the water tank with water, attach the mop cloth, slide the container underneath until it clicks and let the robot run. In the mopping mode, the Roborock cleans for about 40-50 minutes until the container gets dry.

Same dimensions

Both robots have the same dimensions of 35 cm (13.78 in) in diameter and 9.6 cm (3.78 in) in height. The weight is 3.5 kg (7.94 lbs).

Long-lasting battery, recharge & resume

The Roborock has a Li-ion battery with a capacity of 5,200 mAh. It lasts up to 150 minutes which is the longest runtime in the industry. It is enough to cover a cleaning area that is equivalent to 250 square meters (2691 ft2).

The Roborock is ideal for big homes

When the battery is on a 20% level, the vacuum automatically docks itself to recharge up to 80% so it can finish cleaning. When it's done charging, the Roborock resumes the job from the spot it left off.

The Roborock runs up to 150 minutes which is the longest in the business

In case it covered the whole cleaning area, it gets to the charging dock to juice up to 100% with no resumption.

Smart Home support

Both of them are integrated with Alexa-enabled devices and Google Home. If you own any of these, you can control the robot with your voice.

What makes the newest Roborock S6 different from the Roborock S5

Notwithstanding both of them have many things in common, there are some improvements you need to know about. We are here to help you to understand what is different between the two Roborock models.

The newest model has the same glossy finish. The Roborock S5 has three physical buttons on the lid: power, charging and spot cleaning. The newest Roborock S6 houses touch buttons.

Other than that, both cleaners look-alike. Under the lid, you will find a 480 ml dustbin and a cleaning tool under the lid.

The improvements were made with the charging dock as well.

With the new charging dock, you can hide a charging cable inside; it looks sleeker and more minimalist.

The Roborock S6 and S5 can automatically recognize your rooms. When the robot is done cleaning, it divides the map into separate rooms. Then you can choose a particular room to be cleaned at a specific time up to 7 times per week. Also, you can manually merge or divide some areas on the map anytime you want.

Silicone side brush

The S6 has a rubber (or silicone?) side brush that is stiffer and meant to last longer.



The Roborock S6 has a rubber side brush

Water level control and better mopping performance

The Roborock S5 has a microfiber cloth for mopping; the S6 has 10 disposable wipes and the same microfiber cloth in the box. The Roborock S6 water container has a switch that you can toggle up and down which provides more or less water supply depending on your mopping needs. The disposable wipes are good for those who don’t like to wash the mopping cloth by hands. Once the mopping is done, you can tear it off and throw away. As an alternative, you can use the reusable mopping cloth and clean it under water after using.

The Roborock S6 comes with an advanced water tank, microfiber cloths, and 10 disposable wipes

The water tank of the Roborock S5 looks the same but lacks the switch that controls water supply.

Upgraded cleaning brush with detachable parts

The Roborock S6 has a new cleaning roller made of an international first-line brand DuPontTM Zytel material. It is a mix of bristles and rubber which makes the brush ideal for multisurface. Its parts are detachable that allows you to remove hair with ease. The new cleaning brush has 250% more bristles than the old one.


The Roborock S5 brush (on top) is solid, the Roborock S6 cleaning brush has detachable parts

Strong suction, carpet boost, climbing ability, and the newest brush make the Robrorock S6 perfect for pet owners.

The Roborock S6 cleaning brush is easier to clean from hair

When we tested both of them on a medium-pile carpet with sand we noticed that the Roborock S5 picked more sand when the cleaning brush was switched with the new, efficient one. More bristles do provide a better pickup than the old roller in the Roborock S5.

The new cleaning roller is essential for everyone who has long hair and pets and does make a difference in terms of maintaining compared to the Roborock S5.

Reduced noise & new filtration system

Roborock did an excellent job of reducing the operating noise level. They optimized the motor vibration and modified the airflow of the fan. It makes the Roborock S6 works almost 50% quieter than its older brother Roborock S5.

The noise the Roborock S6 makes when working is at about 50 dB level which makes it one of the most quieter on the market with strong suction of 2,000 Pa. We did notice the difference between the two models.

Comparing the noise level of the Roborock S6 and S5

The Roborock S5 is definitely noticeable on high power settings, it is one of the main reasons why I prefer the Roborock S6. If you mostly schedule the robot to work when you are not home, it will not bother you but if you staying home when the Roborock is working, you will eventually hear the S5.

If the Roborock S5 can be a little bit distractive especially when max mode is on, the Roborock S6 allows you to sit in the same room where you are and do whatever you were planning to.

Extended warranty

The Roborock S6 has a two-year warranty which is the longest in the industry; the Roborock S5 provides a 1-year warranty.

7 reasons to get the latest Roborock S6

  1. Improved water tank and mopping attachments make the mopping more efficiently.
  2. If any noise distracts you, have a look at the Roborock S6. It might not be the quietest, but let's not forget that it is a powerful machine, it should make noises, right? At least it is not as loud as the Roborock S5.
  3. The new charging dock is minimalist. The charging cord will not be laying on your floor as it used to be with the S5.
  4. With the cleaning roller that has detachable parts, the Roborock S6 is a great choice for pet owners and those who have long hair.
  5. The Roborock S6 supports the Roborock app and Mi Home app when the S5 model — only the Mi Home app.

As much as we love the Roborock S5, it is a great machine, we couldn't resist the new features of the Roborock S6. However, if you already own the S5 model, there is no reason to buy the S6. The S5 is still a very decent device for the price.

Side note: The Roborock S6 supports the Roborock app that is, in my opinion, more minimalist and user-friendly. However, if your smart home ecosystem is synced with other Xiaomi devices, the Roborock S6 can be connected to the Mi Home as well. The Roborock S5 only supports the Mi Home. The noise. When the Roborock S5 is working is is very noticeable. You always can tell where it is since it is almost as loud on Max mode as it is on Eco mode. The Roborock S6 is much quieter and I would personally get the S6 only because of the reduced noise. The cleaning brush in my case does make a difference too. As a long hair owner, I struggle to maintain the Roborock S5 brush. The hair stuck at the edges and is not easy to get while the S6 roller can be disassembled for easier maintenance. And also, the new brush has more bristles which help to pick up more on carpets, based on our tests. As to navigation, it might not be a big deal but if you have a big house, the Roborock S6 will finish the job faster. And the mopping, if you are going to use it from time to time, you might want one that has a water flow control and different types of mopping pads. The wipes are ideal if you don’t want to wash the microfiber mop but are not suitable for big jobs.

If you don’t need the mopping feature, check out the latest Roborock S4, it is cheaper than the Roborock S6 but has almost the same features. If you would like to have the mopping function, take a look at the Roborock S5 Max, it has improved and much better mopping function.

In short: if you want a robot that is quieter, you have long hair or a pet, need more smart features and live in a bigger house, get the Roborock S6.

    Hey there,
    Its a very nice website that you are running about RoboVacs, please keep up the good work. The website is really very helpful in sharing detailed information about all the robovacs available in the market, specifications etc. Added to it the comparison feature is most useful. It would be better if you can add more functionality to compare more than 2 products at any given time.
    I have a few questions to ask:
    1. How is Roborock S5/50 different from Xiaomi Roborock Mijia and why are they calling it with different names instead of a single name or common nomenclature «Roborock or Xiaomi». This is causing confusion in the psyche of potential buyers. Today I read another review on this website which spoke about «Xiaomi Mijia 1S Robot». Elsewhere also, I read that Xiaomi owns Roborock, then why are they coming with different brand names as Roborock S5/T6 and Xiaomi Mijia 1S Robot instead of Xiaomi S5/T6?
    2. I live in a duplex villa which has two levels. Given your experience with Robovacs and using your good offices & contacts, do you think the Roborock S5 will upgrade/update their existing S5 mobile software app with Multifloor map functionality since this feature is available by default in T6.
    Hope I havent asked too much. Thanks in advance. Have a great day. Cheers!!!

      thanks for the kind words and your feedback! The ability to compare more than two robot vacuums will be added soon. It's almost done but works not as expected, so we need to improve it.
      Regarding your questions:
      1. There is a lack of info about the Xiaomi Mijia 1S Robot at this moment. Probably it was developed by the same company Roborock as the first Xiaomi Mi Robot and will be presented as a product from Xiaomi (without mention of Roborock). However, I have no idea why they use different names instead of a single name. At the same time, Roborock presented the newest Roborock T6 under their own brand. So far we know that the Xiaomi Mijia 1S has a very similar appearance to the first generation Xiaomi Mi Robot with a few improvements.
      2. Unfortunately, I don't know if they are going to add multifloor map functionality to the Roborock S5.

          A question about main brush. Would s6 main brush fit s5 model? and the same question about side brush…
          1. Natalie Red
            #      0
            Yes, both brushes fit very well, so you can use the S5 brushes with the S6 model, and vice versa.

            Thanks for the really great review!
            Just a few weeks ago I bought the Roborock S50, I just can't believe that just now they have released the next gen!
            I don't think I will buy the S6 since I've just bought the S50, and it seems like the differences between them and the improvements in the S6 are not that worth the hassle. But since I have two cats and a girlfriend with long hair it does take a bit of time to remove the hair from the brushes. So if you can advise me on where I can buy the S6 brushes for my S50 that would be great!

              Hi Daniel,

              You are right, the Roborock S6 has a cleaning brush that would be better in your case, it does take less time to clean the new roller.

              Unfortunately, so far we don't know where you can buy accessories for the Roborock S6 and when it will be available since the robot has been announced not so far ago. Hope, you can buy a brush next week or so.

                Is this Really true in the review?
                ”Also, the Roborock S6 stores multiple maps (up to 3) which makes it ideal for houses with one and more levels. The Robrock S5 is only able to save one map.”

                I mailed roborock support and asked them about this I got this answer.

                Hi Thomas,
                Thanks for your interest on Roborock.
                We are so sorry to tell you the model S5 and S6 could only save one map at present. It will recreate a new map once you move it to another floor.
                For multiple map saving suggestion, we will forward your advice to our developing department and hope they will add this feature in the future.”

                  Hi Thomas,

                  It's strange. I'm sure it can store up to three maps, you can check the screenshot below. Since I have only one floor, I put it on a balcony and to our testing zone, and as you can see it saves all the three maps in the app, I can choose any map anytime before starting cleaning.

                  Hi Again,

                  Of course I asked the support once more and got this:

                  Lora (Roborock)
                  May 17, 15:38 CST

                  Hi Thomas,
                  Actually, the model S6/T6 could save 3 maps. One is the map first created. One is last time cleaning' map. One is the map which contains barrier and no-go-zone.
                  However, you could not choose any specific cleaning map log to save. Besides, you could not name saved maps.

                  To sum up, the multiple map saved function of model S6/T6 is not well made at present and could not meet customers' need, which is reason why we don't suggest customer uses it.”

                  A little bit confused. Can it be that you draw up a new Map as long as you dont got 3 of them. And IF you dont reset a map, the robot will never draw a new one. That is use one of the stored ones. Then maybe it is suitable for 2 floors?

                  Help me out!
                  1. Natalie Red
                    #      +1
                    If you already have three maps saved and you want to create a new map, the oldest map will be replaced with the new one. So you always have three latest maps.
                    However, according to the support response, if you have a map with virtual barriers, it will not be replaced even if it is the oldest one. At least this is how I understand it, haven't tested it yet.
                    Also, today I updated the app and seems like there are some improvements: now you can manually delete any map (see the screenshot below).
                    Worth to mention, the S6 saves a map only if it has been started from the charging dock and automatically returned to it after cleaning. If you manually interrupt the cleaning process or the robot does not find the charging dock, the map will not be saved. This is how it works so far. So looks like this is what they mean by this: «However, you could not choose any specific cleaning map log to save.»

                      Sorry, what do you mean? We have tested both models, and as you can see on the photo above, they have different side brushes: the S5 has nylon bristles when the S6 — silicone bristles.

                        Hi, I can't find my S5 so I tried to use the dock from the S5 Max which looks the same as the one used for the S5.

                        The Roborock S6 is compatible with the S5 Max dock, it recognizes it on the map and can park itself and the same with the S5 Max unit, it can be charged with the S6 dock. Can't say for sure how it will work in a day-to-day cleaning but seems to be just fine for now.
