We have many companies already making these cleaners, iRobot was one of the first Robo-vac makers with the Roomba, they even have a wet washer called the Scooba. We even have some household brands like LG and Samsung manufacturing them and an brand easily available in India by the name of Milagrow also makes and sells these autonomous vacuum cleaners. However, the one thing in common for these lean and autonomous cleaning machines is the price. They usually cost upwards of $400 for a decent vacuum cleaner. Xiaomi wants to change this and they have launched the new Mi Robot Vacuum.
Just like Xiaomi phones, Mi Robot Vacuum cleaners are loaded with specs, for starters you have 12 sensors including Laser Distance Sensor (LDS), ultrasonic radar sensor, cliff sensor, gyroscope and accelerometer. The Mi Robot Vacuum has a 1800Pa air pressure capable bristles DC motor. The best part, it sells for RMB 1699 or Rs. 17,000 (US $ 250 approx).
It will clean for a 2.5 hours straight with a 5200mAh battery, and it syncs up with the Mi Home app, so that you get the ability to control robot remotely. We always wanted remote control toys that would have a bigger purpose in life. The Mi Robot Vacuum has pneumatic brushes that automatically adjust height to create tight seal with floor.
