Xiaomi Mijia 1T vacuum robot launched in China 🤖 Navigation wonder?
Xiaomi’s own brand, Mijia, also launches products under the “Mijia” flag in the main market of China. Internationally, the company is advertising with the Xiaomi logo because of the many fans. Even before Singles Day, Xiaomi has now launched the Mijia 1T in China. It has so many sensory qualities that it could become a real “navigation miracle”.

Xiaomi Mijia 1T: Packed with sensors
The new 1T looks a bit like a mixer from the Xiaomi models Mijia G1, Mijia 1C and LDS version. The first ones should already have jumped from this article, because they will inevitably have recognized a built-in camera in the picture above and cameras are “too unsafe” for household use.
In fact, this is a 3D VSLAM graphic sensor which allows the creation of a virtual map and optimized obstacle detection (VSLAM = Visual Simultaneous Localization And Mapping). All without a laser distance sensor. We know this from the Deebot Ozmo T8+, which provided better obstacle detection results than the powerful models with LDS.
As always, app control is also possible via Xiaomi Home (Android, iOS), where the virtual map of the premises is also displayed (live mapping). Due to the 3D obstacle detection the flat design of 8.1 cm height is possible. However, this makes it 0.2 cm higher than its ecosystem competitor Dreame F9, which is currently by far the best vacuum robot around $200 and without LDS.
But the 3D sensor is not all. On the top side there is an optical TOF sensor (Time-of-flight), which we know from the Mi Robot 1S. With this optical sensor, doors and passages are detected more precisely. From a technical point of view, the vacuum robot measures distances with the TOF using a time-of-flight method (speed + distance). Optical sensors are devices that detect objects by means of light and should not be confused with cameras.
Working time is indicated as 3 h, which in all probability refers to the lowest of four suction stages. At the highest suction level, a value of 3000 pa is given, which means that the round household helper would even outperform the Roborock S5 Max in this discipline.
Outlook and assessment
The vacuum robot costs $350 in China, but experience shows that it will be a little more expensive for us here. But why is Xiaomi launching the robot before Singles Day? Possibly to be able to offer a strong price on 11.11.? Possibly, because the official sale will start on the big shopping day. We see a good chance to get the robot at AliExpress for a good price on that day. It is unclear what the price will look like afterwards.
It is also unclear how well the navigation with the many sensors works in practice. With the Dreame F9 we noticed that a vacuum robot does not necessarily have to have a laser tower to navigate well. Since the 1T has even more built-in technology, we can be very excited about this. Also because the price for the Xiaomi vacuum cleaner without LDS has always been manageable.
We find the Mijia 1T absolutely exciting and hope that it will already be available for us on Singles Day. What do you think of the new robot from Xiaomi’s ecosystem?
