In 2016, the first vacuum cleaner robot produced by Xiaomi was launched, soon becoming one of the most successful vacuum cleaner robots. Meanwhile, Xiaomi have launched several new models, with mop function (Roborock S50 / S55, Roborock S6, etc.), and at the beginning of this year there was also the long awaited upgrade for the first generation, the one without mop. Like the first model, it is also produced in collaboration with Mijia, and now bears the name of STYJ02YM.
Even though it has been 3 years since the first Xiaomi robot vacuum cleaner was launched, the differences between the 2 models are not very big, but there are. Xiaomi Mijia STYJ02YM has higher suction power, is quieter, knows how to recognize and differentiate every room in the home, thanks to artificial intelligence (AI), and has lower power consumption. In short, these are the most important news that Mijia STYJ02YM brings. Whether or not it is worth the money difference, you decide.
In terms of appearance, Mijia STYJ02YM retains the design that enshrined it. Unlike the previous model, an optical sensor appears on the front panel near the LDS. As you probably know, the vacuum cleaner relies on the built-in distance sensing laser (LSD) sensor to scan 360 degrees inside the home. This time, the LDS sensor is also a help, namely the optical sensor, which better captures the objects, doors and more “complicated” areas of the home, to better orient themselves.
Also, the LDS sensor receives improvements, but also a more efficient algorithm. This makes the vacuum cleaner more efficient, saving the fastest routes to get to certain places in the house. This means that it will save energy and will not pass 2 times through the same place.
According to the manufacturer, it has improved cleaning efficiency by up to 13% compared to the previous model. Obviously, the rest of the sensors we find in previous models, such as: gyroscope, accelerometer, speed sensor, collision sensor, dust ladder sensor, drop sensor, etc. are also missing.
The suction power increased to 2000Pa compared to 1800Pa – valid for the first generation Mi Robot, now having the same power as the Roborock S50. It can recognize the carpet or carpet, and depending on the surface, the suction level increases or decreases to ensure the best cleaning.
As I mentioned at the beginning of this article, the Mijia STYJ02YM is even quieter, so depending on the mode of use, the maximum noise it can make is 65 decibels (Quiet – 50 dB 1200 pa, Balance 55 dB 1400 pa , Turbo 60 dB 1800 pa and Max 65 dB 2000 pa. The battery is also 5200mAh, being able to provide up to 2.5 hours of use.
Like the rest of the models in the Xiaomi portfolio, for the configuration and use it uses the Mi Home application. Who do I think Mijia STYJ02YM is for? Personally, I find this model useful for those who want the performance of Roborock S50, but do not need the function for the mop and do not want to pay extra for nothing.
