2nd Generation Xiaomi MiJia Roborock is The Most Powerful Smart Robot on The Market

This year Xiaomi introduced their second robot vacuum cleaner: the Xiaomi MiJia Roborock. What makes the 2-nd generation of Xiaomi Roborock one of the best devices on the market? This robot vacuum has very similar specifications compared to other flagship robot vacuums like the Roomba 980 or the Neato Botvac D7. Hovewer, the main difference is its costs that significantly less than competitors with similar functionality.

The Xiaomi Roborock comes with strong suction of 2,000 Pa which makes it one of the most powerful robots on the market. Unlike the cheap robots with a random moving pattern, the Roborock builds a map of your house and plans the most effective path to clean all rooms in the shortest possible time. The second generation of Xiaomi robot vacuum can not only sweep but also mop your floors. The upgraded app where you can monitor it movement in real-time, control and schedule the robot and many other great things that customers love in this robot vacuum. Sounds great? So is the new generation Xiaomi Roborock better than other robot claners on the market? Let's find out.

Smart Navigation Technology

A special Laser Distance Sensor (LDS) scans surrounding area 360 degrees. The LDS maps out the interior helping the robot better navigate while the Simultaneous Localization and Mapping System with three processors located inside the robot tracks its movements in real-time calculating the most efficient way of cleaning without getting lost.

Sensors that help navigate the Xiaomi Roborock

The Xiaomi Roborock is equipped with 13 sensors including LDS that help the robot navigate:

  • 4 cliff sensors help the robot avoid a fall.
  • A wall sensor keeps the robot from bumping into furniture and stops it at a distance of 0.4 inches (10 mm) from the obstacle.
  • The Roborock is equipped with an extra soft crash bumper to protect your furniture.
  • A technology called the "omnidirectional pressure sensor" can now avoid areas where the robot bumps with its "head".
  • A drop sensor activates when the robot is lifted so it stops working immediately.
  • Double Electronic Sensor identifies virtual walls.
  • Thanks to infrared sensor, the robot can find the charging dock without any issues.

The Roborock cleaning performance

The barrier height is increased from 0.4 in (1.5 cm) to 0.78 in (2 cm), the suction power is 2,000 Pa, which is awe-inspiring because even the Roomba 980, the high-end robot from iRobot designed for carpets delivers only 1670 Pa. The 2nd Generation Xiaomi comes with a 2 mm soft bumper that provides a low-noise operation.

The Xiaomi Roborock performs great on any type of bare floor, thin and medium-pile carpets. Because of its 3-stage anti-tangle design, the robot doesn't have issues with hair wrapping which makes the robot ideal for pet hair.

Intelligent carpet identification (Carpet Boost)

Once the Roborock identifies the carpet, it automatically increases the suction power to maximum providing deeper cleaning. After leaving the carpeted surface, the robot returns to the normal suction mode.

Three-stage tangle-free design

Tangling hair can be annoying while cleaning the main brush of other robovacs, Roborock's main and side brushes are tangle-free along with its wheels. The design helps to protect the device from overheating with the bearing stuck to the motor.

Wet mopping function

This robot is great for houses with bare floors. It is equipped with a detachable cloth and water tank. The water tank is installed into the bottom of the device. It holds around 100 ml of water, enough to mop for 45-60 minutes. The intelligent system works by the main principle of the plant bionic system and controls the water by itself. The sliding mechanism is designed in such a way that water drips wisely, only when the robot is moving.

Washable HEPA filter

The E11 washable grade filter designed with a Teflon cover provides 95% effective cleaning. Wash it with water and let it dry. Do it only once in a week though. You have to change it once a year.

A long-lasting battery

The new Xiaomi Roborock comes with a 5,200 mAh Li-Ion battery which provides 2.5 hours of working time which equals cleaning about 2700 sq. ft (250 sq. meters) of house area. A LED battery indicator displays the charge level via different colors while the battery is juicing up. The white light means the battery charge level is more than 50%, yellow - less than 50%, red - the charge level drops below 20%.

The improved charging base has a protection from an over-current, overvoltage and short circuits. When the robot's battery runs out, it will find the docking station using 2 laser sensors.

Recharge & Resume Feature

The recharge and resume feature will be very helpful for those who have a big house. It can automatically recharge and continue cleaning from the same stop it left off in case it didn't finish cleaning before its battery had died. 150 minutes of cleaning sounds impressive. Xiaomi Roborock is the only robot cleaner on the market that can last this long.

Operate the Roborok with the upgraded iOS/Android MiJia App

With the MiJia app, you can create virtual walls, navigate the robot to clean a specific area, schedule the cleaning time multiple times per day, etc.

The new Mijia application syncs with the Roborock so you are able to see the map of the house and easily navigate the vacuum by drawing the special area of the map on your phone (as shown on the picture below). This feature is incredible because the robot can clean a specific area of your home without actually using a virtual wall or just blocking it. You can navigate the robot by tapping on your screen and it will go towards the target.

You need to drag the scan box on the phone map to set the cleaning area using the MiJia app

The Mijia app allows 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. You can track the whole process and manage your robot even when away from home.

Who the Xiaomi Roborock 2-nd generation was designed for?

The Xiaomi Roborock has a lot of features that will make your life much easier, especially when it comes to cleaning your floor.

  • This robot is the perfect alternative to an upright cleaner for people who have pets because the tangle-free design makes it easier to collect long human hair along with pet hair without getting tangled around the main brush.
  • It is perfect for all bare floor types including tile, laminate and hardwood because of the mopping feature. Now you don't need to worry about wet cleaning. Just install the water container and click “Start” using your smartphone or manually press the "Home" button.
  • Roborock's powerful motor is designed to deep clean houses with mostly carpeted surfaces.
  • For those with a bigger house than average, this device is ideal because of its long working time and recharge & resume feature. While other robots randomly navigate for about 100-120 minutes and get recharged when the battery runs low, Roborock cleans the whole place for 150 minutes and resumes after recharging from the place it has left.
  • Because it is an app-based robovac, you can manage it from your phone. For example, if you need to clean the floor because visitors are coming in the evening, but you are not home, just press "Start" on your screen and by the time you are home, Roborock will have already finished its job.
  • HEPA filtration inside is good for people who suffer asthma and allergies.

Is the Xiaomi Roborock worth buying?

The second generation of the Xiaomi MiJia Roborock is definitely better than the Xiaomi Mi Robot, but the price of the device is higher. The suction power of 2000 Pa is enough to pick up long human or most pet hair; and if you have any carpeted surfaces, this vacuum cleaner is perfect for deep cleaning. Plus, the tangle-free technology is an amazing feature for those who don't like to rid all the brushes of everything stuck in them. Constantly untangling stuck hair can be really annoying. Do not forget about the new mopping function because it is a rare feature that makes the Roborock good enough for any surface including hardwood floors, tile, laminate, and carpeting. The upgraded navigation technology allows the robot slide through rooms without bumping into things, mapping the area and choosing the most efficient path to work. The MiJia app is phenomenal; it has a lot of things that even Roomba robots don't do. In any case, it still can be an expensive robot vacuum cleaner with a $550 price tag. But will you find anything similar to the Xiaomi Roborock for the price of $550, having all the features and great cleaning performance? So the main question is the second generation of Xiaomi Roborock vacuum cleaner worth buying? Definitely yes!

    I bought this because it was very affordable at a good price and general opinions stated there were few problems other than the wheels getting stuck, the step is too high, failing to clean carpet, etc. I also still had some faith in Xiaomi despite a string of failures.

    What happened instead was: after only 2 months, it seemed the motor fan had stopped working so the motor started to overheat(or so our electrician told us). The exterior of the casing cracked and melted. We would've taken photos or videos but we were too busy trying to prevent a fire from happening. Some of the floor wood panels were starting to burn from the melting plastic!

    The apartment was built less than 7 months ago, we regularly unplug devices we don't use and so on. The robot's exterior btw, was dry wiped frequently to prevent dust from clogging the interiors. So, I doubt it was an issue on our end.

    This isn't the first Xiaomi product to fail on us and some failed within barely 3 to 6 months. All were obtained directly from the MiStore in either China or Singapore. Rice cooker heating coil failed, Redmi Note 3 screen started to leak internally, air purifier stopped working, etc. It seems their products are really affordable but they must be skimping on some of the QC or quality of internal parts, to set such a low price. We do have other Xiaomi products which are still working like their power banks, their router, kettle, etc. but our confidence has been dented. We did manage to get many of the problematic devices repaired or replaced but I won't be buying another Xiaomi product again.

    I guess this is my lesson: you get what you pay for. I'm not too sure if I'll get a robot cleaner ever again! If I do, I'll make sure it has more safety checks!
