1,699 yuan: Xiaomi's robot vacuum, designed by Roborock, maps the home with a laser

Roborock, a company in the Xiaomi ecosystem, developed the device. According to Xiaomi's page, it has 12 sensors to move around and clean. Its 5,200 mAh battery gives it 2.5 hours of battery life. Cleaning can be scheduled and monitored from the Mi Home app.

On each run, the robot draws a map of the home in real time. According to the manufacturer, this lets it follow an efficient route, and avoid going over the same spot twice or missing areas.

A Nidec brushless motor provides 1,800 Pa of suction. Xiaomi says this places it among the most powerful models on the market.

The page announces a sale in China from 6 September, at a price of 1,699 yuan, on Xiaomi's website and in Mi Home stores.
