Xiaomi unveiled its Mi Robot Vacuum, the latest addition to its smart home product line, as the company continues to drift further away from its core smartphone business toward a diversified internet hardware ecosystem. The Mi Robot Vacuum will cost RMB 1,700 (about $254 USD) several hundred dollars cheaper than its overseas equivalents. The first items to go out of stock were rice cookers, blow dryers, heated toilet seats, and yes, robot sweepers. According to research firm IDC , Xiaomi’s smartphone sales plunged nearly 40% compared to last years’ second quarter – not exactly something to brag about. The company has even begun to distribute product catalogues, further emphasizing its image as an appliance – not smartphone – company.
