The American robotic vacuum cleaner manufacturer iRobot is grappling with intense competition from Chinese counterparts, leading to a sustained decline in its performance. Subsequent to Amazon's decision to abandon its acquisition plans, iRobot's share price plummeted by 36%, marking an unprecedented single-day drop in the company's history. In the fourth quarter of last year, the company's sales witnessed a year-on-year decline of 44%, accompanied by losses amounting to $77.1 million. Currently, the global market for smart robotic vacuum cleaners is largely dominated by Chinese companies, which has resulted in a consistent erosion of iRobot's market share. Despite the launch of eight new Roomba models, the market reception and performance of these products remain uncertain.
