Is The New Xiaomi Robot Better Than The 1st Gen and Why? Roborock vs Mi Robot Vacuum Cleaner Comparison

Xiaomi released the upgraded version of robot vacuum cleaner the Roborock S50 we talked about in our review. The previous model, Mi Robot, comes with a bunch of features that make it one of the best in its price range, but the new one just blew our minds with all the high-end features. Both have a smart navigation system, perform great on carpets, and in general are worth every penny considering their cleaning performance.

What makes xiaomi robots one of the best budget smart cleaners on the market?

  • The longest-lasting battery.
  • Accurate map
  • Better navigation system. The robots recognize obstacles and don't bump into it when working
  • Efficient cleaning pattern
  • Great carpet performance. Most the expensive robots can handle medium-pile carpets while Xiaomi robots do both: low-pile and medium-pile carpets costing less than most of the competitors
  • Because of the accurate map the robot builds, it is able to resume the cleaning process from the point it left when the battery was 20%, and the machine had to get back to recharge.

Design & appearance

In the Xiaomi Roborock the «head» moved from the top of the lid to the center. The 2nd version has three buttons: spot cleaning mode, home, and recharge. It is still the same minimalist black&white design that looks slightly different from the previous version.

Suction Power / Running Time

  • Both robots last about 2.5 hours which is longer than most of robot cleaners on the market. Thanks to the recharge & resume feature, the robot covers a large area in one charge which makes each of them ideal for biggest houses.
  • The suction power has increased from 1800 Pa to 2000 Pa.
  • The Roborock S50 can now mop the floor. It works for about 45-60 minutes in this mode, making the robot suitable for bare floors, carpeted and mixed surfaces.

The Mi Robot vs. Roborock Features

  • The new MiJia Roborock comes with a LIDAR system. The laser is located inside its "head" helps to map out a cleaning area. Mi Robot comes with 12 sensors while the 2nd gen has 13 sensors. The sensors help the robot to navigate around in the most efficient way without bumping into furniture and falling down from stairs;
  • The new feature - “intelligent carpet identification” (only presented in Roborock) — once the device recognizes a carpet, it turns on the maximum mode and reverts back to the regular mode when the robot is leaving the carpet providing deep cleaning;
  • Obstacle climbing ability has increased from 1.5 cm to 2 cm;
  • The feature "recharge & resume" allows the device to get back to work after recharging in case the battery runs out and the robot doesn't finish its job;
  • While the Mi Robot is equipped with a regular HEPA filter, the new robot has a washable one. It is not a big difference, but it is definitely good for people who suffer from asthma or allergies.
  • Forget about tangling hair because the new MiJia is designed to prevent motor hair from getting stuck. Not a big deal, but anyone would love to think less about things like this, right? Please note, that hair will stuck anyway but not as much as in previous model.
  • The omnidirectional pressure sensor helps the Roborock to avoid an area that it bumps with its «head»;
  • Although the new generation has more suction power than the Mi robot, it comes with a closed silence cotton and porous air sieve that makes it work quieter, making only 54-67dB of noise compared with 61-72 dB in the first gen.
  • The upgraded smartphone app has an ability of creating zones that should be cleaned, send the robot to the point you want just by tapping on the map on your screen etc.

There are three processors inside the newest robot cleaner that track its movement in real-time which you can watch on your smartphone. You can navigate the device using the new app simply by tapping on a specific area you want to clean, and the robot will do the rest. You can create a digital walls as many as you want, so the Roborock will not go through it just by drawing the area you'd like the robot to clean on the map built by the Roborock. The feature is great simply because you have the possibility of managing your home assistant when you are away. To wrap it up: the Mijia app allows you to monitor the cleaning process, schedule the cleaning time whenever you want, even multiple times in a day, create zones to be cleaned, and choose the name of your new friend.

Xiaomi Roborock S50 - second generation of robot vacuum

Why you should or shouldn't buy the new robot vacuum MiJia Roborock from Xiaomi?

There are reasons to buy Roborock instead of the previous cheaper vacuum, Xiaomi Mi Robot, even though both robots are among the best in their price range. The powerful motor provides a deep cleaning of all carpet types without having an issue with hair tangling (thanks to the tangle-free design). This design makes the latest robovac from Xiaomi ideal for pet owners. In fact, the Xiaomi Mi Robot also does its job well on carpets even though it has 1800 Pa of suction power, while its brother has 2000 Pa. Both robots are equipped with a 5200 mAh battery that lasts the whole 2.5 hours on a single charge.

Both devices come with the mapping feature and smart navigation system. Xiaomi 2nd Gen is 2-in-1: sweep and mop, making it perfect for hardwood floors, carpeting and mixed surfaces. Its older brother, Mi Robot, can only sweep. Roborock is probably the smartest robot vacuum cleaner on the market so far. With its SLAM algorithm and a Laser Sensor, it maps a cleaning area and chooses the most efficient way to clean on its own, providing more thoughtful cleaning. Along with its smart navigation, Xiaomi's newest robot vacuum cleaner has carpet identification that helps the device to recognize a carpet and switch the maximum cleaning mode automatically. And last but not least, there is the new amazing MiJia app - in my opinion the best application to manage the whole working process. So, if you have some extra money and you want to buy a robot vacuum, consider the 2nd generation Xiaomi Roborock because even though the device is more expensive than the first Xiaomi Mi Robot, it is worth every penny of its value.

UPDATE: If you want a robot vacuum that is as powerful as Xiaomi Roborock, take a look at the newest 360 S6. It has a nice design, high build quality, very similar features such as intelligent mapping, strong suction power, wet mopping etc., yet costs less.

    How do you setup digital virtual walls?

      Hi Jim,
      As I understand, after Xiaomi Roborock mapped your house you can use the smartphone app and set the area wherever you want to clean. Check the video (start at 0:41):
      Also, there are magnetic virtual walls on the market:

      First gen vacuum also resumes work after charging if it falls under 20% of battery power while cleaning. It goes back to the dock, charge to 80% and then it resumes from the last point

        Thank you for noticing, I've changed it. Not sure why I didn't notice it when writing the article.

        thank you for your review, please note you have switched the Accessories between the two robots.

          Thank you:) I've fixed the comparison table.

          Saying that the new Roborock comes with a feature allowing to create 'virtual walls' is misleading. There is no such feature as far as I know. What you call «virtual walls» seems to be zone cleaning, which is very different in purpose: it's for instructing the robot what should be cleaned, as opposed to where the robot should not go. The fact that zones cannot be saved nor scheduled makes this feature even less useful, but calling it «virtual walls» is truly far-stretched. The only way to create virtual walls is to use a magnetic tape, and the Roborock is no different in this regard from its predecessor.
          1. Michael 22 october 2018, 03:19 #
            you are right, it's not correct to call this feature «virtual walls». I've corrected the text. However, I have heard that the «Blocked areas» feature will be added to the Mi Home app this November. It would be nice to have this feature, especially if it will work with scheduling. The 360 S6 robot vacuum that we reviewed recently, that is cheaper than the Roborock, already has zoned cleaning and blocked areas and it works with scheduled cleaning.

              I agree that having true «virtual walls» (or «blocked areas») on the Mi would be awesome. I did read your excellent review about the 360 S6 and then I thought that perhaps I should have bought the S6 instead :) But Roborock is slightly lower (-0.4 cm) which makes a difference in my case. I think part of the problem is that Roborock has troubles with mapping, ie. it doesn't recognize past maps, and has even troubles recognizing the last one sometimes (it occurs sometimes that it re-maps my floor area rotated by 180 degree, like it would be a totally new place). But perhaps these are things that Xiaomi can fix in software. Would be really really great.

                Great news! The new firmware (version 3.3.9_001632) with the «blocked areas» and «Map saving mode» is already here. You can use those features after updating the firmware. However, you can update the firmware only if you switching the server location to «Mainland China» in the Mi Home app. I think it will be available for all server locations a little bit later.

                  That's excellent news indeed! I did switch to Mainland China, and was able to update the firmware to v3.3.9_001632 then, but unfortunately the app detects that I am not actually in China, and refuses to let me access the Roborock unless I change the server to something else :) I had to switch back to Europe servers and there the feature isn't present — yet. Hopefully the new firmware should spread to all server soon. Yay!
                  1. Michael 23 october 2018, 09:50 #
                    Looks like you have an «International Edition», mine robot is «Chinese edition» and it works with Chinese server. I guess this issue somehow related to GDPR law. I tried a few different server locations but those features work only on «Mainland China» server at this moment. Check this thread, maybe there is some solution how to make it work with Chinese server:
                  2. PHAN QUOC TRUNG 06 november 2018, 03:34 #
                    The new firmware (version 3.3.9_001632) still have not «blocked areas» and «Map saving mode»
                    1. Michael 06 november 2018, 09:42 #
                      As I mentioned in the comment above, at this moment it works only when you are connected to the Chinese server. Go to the Mi Home settings and change the server location to «Mainland China». After that, the blocked area icon should appear in the top-right corner, like on this screenshot:

                        Is this new feature available both for 1st and 2nd generation?
