Xiaomi Mi Robot Vacuum Cleaner Review


The Xiaomi Mi Robot Vacuum cleaner is one of the most advanced robots used for house cleaning and this status is given by some of its key features such as the LIDAR based navigation system and laser distance measuring unit, technologies that are not found on most of the other existing models on the market.

Availability and parts


I will cite WIKIPEDIA now: “Lidar (also called LIDAR, LiDAR, and LADAR) is a surveying method that measures distance to a target by illuminating that target with a pulsed laser light, and measuring the reflected pulses with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3D-representations of the target. The name lidar, sometimes considered an acronym of Light Detection And Ranging (sometimes Light Imaging, Detection, And Ranging), was originally a portmanteau of light and radar. Lidar is commonly used to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. The technology is also used for control and navigation for some autonomous cars. Lidar sometimes is called laser scanning and 3D scanning, with terrestrial, airborne, and mobile applications.”

As you can see, this is a highly sophisticated piece of tech that found its way on this vacuum cleaner and Xiaomi is using it for fully mapping your home thus optimizing the robot route, room to room navigation, generating full floor cover and safely returning to the docking station.
The Xiaomi Mi Robot employs other sensors such as a sonar, cliff sensors and touch sensors thus increasing its accuracy so great that the vacuum will even circle table and chair legs to have a perfect coverage and will know its way back so the chances of it getting stuck are minimal.
With all this tech and running a balanced profile that will somewhat reduce the noise and speed the robot will cover a highly intricate map of workable 33 square meters with 4 rooms and a hallway in about 40 minutes while the battery will be drained to just 79%.
The wall distance detect on this model is also impressive and employees a second laser measurement unit and will keep the robot navigating at a fixed 10mm range which is specially calculated so that the side brush will provide the best efficiency to cover the space, gather and direct all the particles on the floor to the main brush so they can be sucked in.
To improve dirt gathering the vacuum employs one side brush to help it gather dust from corners and side walls while the main rotating broom will get more stubborn stuff such as hairs. The Mi Robot motor develops and impressive 1800 mPa suction power enough to lift big particles such as sand, crumbs, fuzz or dust bunnies. The main broom is also a composite type and uses bristles along with silicon blades further increasing the pick-up power while keeping hair tangling at minimum.
All the dirt is gathered in a large dustbin which also holds the HEPA grade filter. To further increase user convenience the dust bin has a position sensor and the robot will warn you of it’s absence so that you will not be able to vacuum without it !

As like all other Xiaomi devices, their Mi Vacuum employs minimalist design and only has two buttons on it, the power on and go to home switches, all the settings are done through the Mi Home APP. The vacuum will connect to your local WiFi network and have access to internet where it connects to Xiaomi cloud and can download new firmware updates and also will provide remote connectivity so you can control it remotely from any corner of the world. The best thing is that recently Xiaomi pushed an English pack update and now the app and the robot voice are no longer in Chinese only.

Further on I will continue with the video review in which I will show you all the apps functionalities and settings, how the vacuum operates and how to set it up the first time.
