Viomi V2 vs Roborock S6: the Differences Explained

By Natalie Red·May 13, 2019· 6 min read

The Roborock S6 and Viomi V2 are two newest robot vacuums released recently that look very promising considering the price and . Both beasts have great features such as strong suction, wet mopping, lidar-based smart navigation, app control which allows you to set restricted areas and perform zoned cleaning. Recently, we have an opportunity to test and review the Roborock S6 and I want to tell you that it a very powerful and smart device. Despite the low price of $389 for the Viomi V2, is it a better choice than the more expensive Roborock S6 with a $599 price tag? In this article, I will try to compare the main features of both robot vacuum cleaners, show you the pros and cons of each model.

The Roborock S6 has everything we loved in the previous S5 model and some improved and new features. It has a better ARM processor than the previous model and much faster and accurate navigation, it knows your home and where exactly it should clean with an improved water tank and advanced mapping. 

The Viomi V2 is the first device in Viomi model line that uses an LDS sensor (or lidar) to scan your house and to build a precise map. And if Roborock knows how to produce a decent robot cleaner since they already made a few successful robot vacuums, Viomi is a bit new in this area.

Both models can mop and sweep, support zoned cleaning and restricted areas, build an accurate map, etc. So are there any other things to consider buying the Viomi V2 over the Roborock S6? What makes the Roborock S6 one of the smartest in this price segment?

Roborock S6 vs.Viomi V2 which one is better

The Roborock S6 took all the great features users loved about the Roborock S5 and added new options.

It delivers the same 2,000 Pa of suction, has the same 20 mm clearance and dustbin size but got quieter than the older model.

The Roborock S6 automatically divides the created map into the rooms after finishing cleaning

The robot vacuum cleaner identifies carpet surface and boosts suction power providing deeper cleaning.

The app supports restricted areas, zoned cleaning and the newest feature - scheduling the robot to work within a certain room at a specific room.

The robot is also perfect for bigger houses thanks to the multiple mapping storage.

Get the Roborock S6 if you...:

  • Live in a big house. Thanks to the longest-lasting battery and resumption the Roborock is perfect for big homes.
  • Your home is mostly covered with carpets. Because of the strong suction, good clearance and carpet identification, the S6 provides deeper cleaning on thicker carpets.
  • Want to have an ability to schedule the robot to work in a particular room.
  • Have a pet. Even though the S6 does not have a big dustbox, it's cleaning brush has detachable parts that make cleaning it from pet hair easier. And strong suction picks up pet hair even on thicker carpets.
  • Live in a multiple level house.
  • Want a powerful robot vacuum cleaner that does not make lots of noises.
  • Want to have an ability to set restricted areas and zoned cleaning. Do not forget about the new feature with which you can also make the robot work in a particular room.
  • Someone in your family or you suffer from an allergy.
  • Want mopping. Yes, the Roborock S6 has a smaller water tank but if you don't have lots of space with no carpets - the newest water level control and a few types of the mopping pads would be very useful.

Viomi V2 glance

The Viomi V2 has the strongest suction power of 2,150 Pa which is insane. The robot is equipped with ten sensors that help it to navigate including the LDS laser that scans the surroundings to build the map of the floor which makes navigation more efficient.

The Viomi is equipped with a big water tank and dustbin.

Still not the biggest and we would recommend getting it empty after every cleaning, but at least you don't have to clean the dust and dirt in the middle of the cleaning cycle.

The big dust container is better for pet owners.

The Viomi V2 is great for homes with mostly bare flooring thanks to the 560 ml water tank. Most of the robot vacuums have 150-300 ml containers. Two types of mop cloths are suitable for different mopping needs.

The app supports zoned cleaning and restricted areas which is presented in a few models that are based on the LDS sensor.

Get the Viomi V2 if you...:

  • Don't have carpets and want the mopping feature the Viomi V2 would be better since it covers more when mopping before the container gets dry.
  • Have more than one pet. The container is big enough to hold more pet hair.
  • Your home is covered with thin and thicker carpets. Thanks to the strong suction and good climbing ability, the Viomi performs great on carpets.
  • Don't want to spend more on the Roborock S6.
  • Or anyone in your family suffers from an allergy.
  • Want to have an ability to block the robot from going to certain places.

Price & where to buy

Wrap It Up

Both models are great at cleaning carpets and bare flooring. The Viomi has a bigger container, if mopping is important for you and you have a big area with no carpets — the Viomi V2 would be the best in your case. 

If you want some additional options like selected room cleaning, carpet identification, if you live in a multiple-store house and are ready to spend some extra — go with the Roborock S6

    I own the viomi v2. It cleans great, but there literally is no app support. At least in the US. It isn't supported by the Viomi robot or Mi home app. Very disapointing. I would stay away from this model until they have software support

      Hi Jeff,

      Yes, the Viomi V2 looks so good and has to perform well, however, the software support seems raw and needs improvements.

      We hope, the company will fix it as soon as possible because, with no app, this robot lacks many high-end features many consumers paid for.

      All sounds good! Just one question, in the text it says 2 times that the Viomi v2 has multi level support, yet in the table on top it says it doesn't support multi-level maps…

      which is true?

        Hi Willem,

        There is not much information about this model. From what I understand by reading other reviews, the Viomi V2 only saves one map, the way Roborock S5 does. We will have a chance to test it soon and know for sure.

        So if you own a multiple-level house, the Viomi V2 will have to rebuild a map every time when cleaning the second floor. Thanks for noticing, the article has been fixed.

        What is the difference between Roborock S6 and Roborock T6? Are their side brushes similar? And do both of these robots have microfiber (not disposable) mops in the box?

          Нет никакой разницы!
          это одно название: Roborock S6 (T6) Vacuum Cleaner.
          T6 это для Китая, S6 для других стран.
          в комплекте идут две тряпаки многоразового использования,
          и 10 шт одноразового.
