Xiaomi Mi Robot Vacuum
Update (24: September 2017)
The successor model of the Xiaomi vacuum robot is now available. The so-called Roborock S50 Although not marketed directly by Xiaomi, it comes from Roborock, the maker of the first Xiaomi robotic squeegee. You can find more information in our Contribution to the Roborock S50.
Vacuum robots from China are inexpensive and are also enjoying growing popularity in this country. The Chuwi ILIFE models have shown the way. The Xiaomi vacuum robot plays in a significantly higher price range, but also offers a comprehensive range of functions and is more comparable to an iRobot from Roomba.
LAD and other sensors
With the presentation of the Xiaomi vacuum robot, Xiaomi has also shown that the company not only clumsily copies technologies, but can also present technologies developed in-house. A "Laser Distance Sensor" scans the entire environment 360°, a total of 1800/second. With the data obtained, the Xiaomi vacuum robot can move extremely precisely in space. In addition, the so-called SLAM algorithm (Simultaneous Localization and Mapping) calculates the best possible cleaning route and creates a virtual room map. The map can be accessed via the “Mi Home” app.
3 processors (Allwinner R16, STM31F103 and TMS320F28026DAS) with 4 processor cores ensure sufficient computing power. A total of 12 sensors are installed. These include the LDS, but also several ultrasonic sensors for collision and crash prevention, a gyroscope, an e-compass and even an acceleration sensor. This means that the Xiaomi Vacuum Cleaner is not a conventional vacuum robot, but rather stands out among the China vacuum robots thanks to the large number of sensors.
Power, brushes and battery
The suction power is 1800Pa. Inexpensive models from other manufacturers usually only reach 1000Pa! With the brushless DC motor from the manufacturer "Nidec", the robot vacuum cleaner moves particularly quietly through the rooms. The brushes consist of a main brush and a side brush. The main brush can adapt to uneven surfaces, which means the Xiaomi vacuum robot can also climb carpet edges or other obstacles. The power is supplied via a base station, which the device can find its way back to on its own. The battery has a capacity of 5200mAh and allows an operating time of 2 1/2 hours.
Mi Home App
The Xiaomi Vacuum Cleaner is operated using a smartphone or tablet using the “Mi Home” app. This app is responsible for numerous Xiami products and can therefore be used in a variety of ways. The connection is established via WLAN, which means that the device can be controlled remotely even when you are on the go. You can use the app to schedule fixed cleaning times, activate different cleaning modes (quiet, normal and performance) and you can even view the room plan created by the SLAM algorithm, including the current position of the robot.
Spare Parts
Relevant online shops have now also listed various spare parts and an interesting additional part for the vacuum robot. On Gearbest there is, among other things, a two-piece replacement brush set that costs around €7, a fraction of the spare parts for a Roomba or Vorwerk vacuum robot. There is also a virtual wall, which allows the suction surface to be precisely limited. However, the “wall” is a rolled-up magnetic strip two meters long. The price of the “Mi Virtual Wall” is around €12.
Conclusion
With the “MIJIA” vacuum robot, Xiaomi is once again presenting a phenomenal product that (at least) does not need to hide from the usual brand competition on the data sheet. Well-known companies such as Bosch, Sharp and Nidec were also brought on board to develop the device, which makes it clear that Xiaomi doesn't just want to stay on the Chinese market in the future.
Here is a summary of individual reviews of the Xiaomi vacuum robot. The excellent suction power is widely praised. Compared to a Chuwi ILIFE V7S, the Mi robot vacuum cleaner cleans far more effectively thanks to the better environment tracking and the stronger suction power. However, the predominantly Chinese app and the Chinese voice output have been criticized many times. So far, no translated version of the app has been released, All in all, the Xiaomi MIJIA Vacuum Cleaner is probably the best vacuum robot from China!
Update
Hard-working users of www.roboter-forum.com have meanwhile also translated the Xiaomi Mi robot vacuum app into German! The installation is very easy and can also be understood by laypeople. Anyone who has rooted their smartphone only needs to exchange the translated APK in the data system directory. But even users without a rooted smartphone can install the translated app with the help of a tool. You can find more information under this Link.
