Let's start with design and appearance

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

Suction power / Running Time

  • The new generation works for 2.5 h same as the previous robot does but the suction power increased from 1800 Pa to 2000 Pa.
  • Roborock now can mop the floor and works for about 45-60 min in this mode which makes it suitable for any surface.

Technologies Xiaomi Use

  • The new MiJia Roborock have the same laser that helps it to map out a cleaning area. Mi Robot comes with 12 sensors whilst the 2nd gen has 13;
  • The new feature is intelligent carpet identification (only presented in Roborock) — once the device recognizes a carpet it turns the maximum mode on and gets back to the regular mode when the robot is leaving it;
  • Obstacle climbing increased from 1.5 cm to 2 cm;
  • The feature "recharge&resume" which allows it to get back to work after recharging in case the battery runs out and the robot doesn't finish its job;
  • Since the Mi Robot equipped with a regular HEPA filter, the new one has a washable HEPA filter. It is not a big difference but it definitely good for people who suffer from asthma or allergies;
  • Forget about tangling hair because the new MiJia designed to prevent the motor hair that stuck in it. Not the big deal but anyone would love to think less about things like that, right?
  • Omnidirectional pressure sensor helps the Roborock to avoid the area when it bumps with its «head»;
  • Although the new generation has more suction power than Mi robot does it comes with closed silence cotton and porous air sieve that makes it work more quite and delivers only 54-67dB compared with 61-72 dB in the first gen. It is the same noise level almost all the ILIFE robots work with;
  • The upgraded smartphone app perhaps is the main thing to pay attention to Roborock.

Well, the old version is good as well especially considering the price tag Mi Robot comes with. There are three processors inside the new MiJia that track its movement in the real-time that you can see 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. Also, you can create a digital wall so the Roborock will not go through it just by drawing the area you'd like the robot to clean on the map Roborock has built. The feature is great simply because you have a possibility to manage your home assistant when you are away from home. To wrap it up: Mijia app allows you to monitor the cleaning process, schedule the cleaning time whenever you want even multiple times in a day, create virtual walls, 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 some reasons to buy Roborock instead of the previous cheaper vacuum Xiaomi Mi Robot even though both robots are one of the best in their price range. The powerful motor provides deep clean of all carpet types without having an issue with hair-tangling (thanks to the tangle-free design). The tangle-free design makes the latest robovac from Xiaomi ideal for pet owners. In fact, Xiaomi Mi Robot also does its job on carpets well even though it has 1800 Pa of suction power when its brother has 2000 Pa. Both robots are equipped with 5200 mAh battery that lasts the whole 2.5 hours on a single charge.

Both devices have the mapping feature and smart navigation system. Xiaomi 2nd Gen is 2-in-1: sweep and mop making it perfect for hardwood floors and carpeting surface. Its older brother Mi Robot only can sweep. Roborock probably is the smartest robot vacuum cleaner on the market so far. With its SLAM algorithm and 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 the carpet identification which helps the device to recognize a carpet and then it turns on the Maximum cleaning mode on its own. And the last but not least — the new amazing MiJia app that in my opinion is 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 getting the 2nd generation Xiaomi Roborock because even though the device is more expensive than 1st Xiaomi Mi Robot, it worth every penny of its value.

UPDATE: Xiaomi introduced a new home robot — Xiaomi Xiaowa Robot Vacuum that costs less than $300. If you don't need mapping feature or want to save money you should take a look at this model.

      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
