The news Xiaomi is going to launch a robotic vacuum cleaner has been buzzing in the net for almost a month, when some packages had spotted in photos. Later the manufacturer announced the Xiaomi Mi Robot Vacuum showcasing its ambitions concerning this market. Honestly, the Mi Robot Vacuum leaves dual impression – on one hand, it comes with unique and useful features, but on the other hand there are some features we can criticize it as well. Regardless, these facts the Xiaomi vacuum cleaner is going to win many users’ hearts due to its design and smart behavior. We have already reviewed it and learned its key features, so it’s the right time to take the cover off and look what’s inside.
Before starting tear Xiaomi Mi Robot Vacuum down let’s remember what specs list it comes with. The cleaner is packed with a Simultaneous Localization and Mapping (SLAM) algorithm to calculate the map, a brushless DC motor delivering up to 1800Pa air pressure, a 5,200mAh 14.4V lithium-ion battery that is enough to clean up to 250 square meter area in about 2.5 hours and so on. The next astonishing features are its sensors. The Laser Distance SensorLDS provides a 360 degrees scanning (1800 times/second), but there are other 11 sensors. To work with those 12 sensors (LDS, wall, dust bin, collision, ultrasonic radar, cliff, electronic compass, gyroscope/accelerator, drop, speedometer, and fan speed) the cleaner sports 3 dedicated processors: a quad-core processor from Allwinner, a STMicroelectronics ARM processor, and a Texas Instruments LDS image processor. There are also two brushes (the main brush and the side brush). Finally, the cleaner moves on three wheels (two wheels and the caster).
We can say this is the summary of the Xiaomi Mi Robot Vacuum, and may be it’s enough to order your own. You will have to pay 1,699 yuan ($250), which is the way cheaper than the weaker competitor of this device, the Roomba that is priced at 5,699 yuan ($850).
