The robot vacuum cleaner used to be considered an American success story. It was developed by scientists at the Massachusetts Institute of Technology (MIT), who set up a company called iRobot in 1990. Even today, many consumers still use the name of the firm’s breakout product – the Roomba – to refer to all robot vacuum cleaners. But fast forward three decades, and the United States has totally lost its grip on a market that it created. As in many industries, Chinese firms now dominate production of robot vacuum cleaners – and the way they caught up with and then supplanted their American rivals says a lot about the state of the global economy.
The world’s top five cleaning robot makers are now all Chinese: Roborock, Ecovacs, Dreametech, Xiaomi and Narwal Robotics together accounted for nearly 70% of the global market in terms of products shipped in the second quarter of 2025, according to a report by market research firm IDC. The U.S.’ iRobot ranked sixth. For U.S. firms, the lost business is significant. Robot vacuums are a fast-growing market, with global shipments growing 33% year-on-year to reach 15.35 million in the first half of the year, IDC data showed. How did this happen? It is not simply about price. On Amazon’s U.S. store, there is little difference in cost between the major Chinese and American brands. The Roomba Vacuum 2 was on sale for just USD165 in mid-September, making it one of the cheapest products on the market. For Claire Zhao, Senior Analyst at IDC China, the success of Chinese brands comes down to heavy investment in both promotion and research and development (R&D).
“Chinese companies have achieved notable results overseas, quickly boosting sales and brand awareness through e-commerce. Rapid technological iteration directly enhances product competitiveness and user loyalty,” she wrote in a report. Chinese brands are now piling into the U.S. and European markets, where the market penetration of robot vacuums is much higher than in China. The intense competition between a growing number of players is forcing all of them to develop and roll out new products faster than ever before. R&D investment has become critical. Ecovacs has upped its spending from CNY549 million in 2021 to CNY1.34 billion in just the first three quarters of 2024, according to the company’s financial report. Roborock invested CNY971 million last year, equivalent to 8.1% of its total revenue.
With the leading firms prioritizing international expansion, brands are focusing on developing hi-tech, premium products. New vacuums feature everything from advanced artificial intelligence to robotic arms, said Janet Su, Sales Manager at a home appliance manufacturer based in Guangdong province. “Chinese players are racing each other to launch new products every six months, or even every quarter,” said Su at the Guangdong Quality Product Exhibition in Guangzhou.
New players continue to jump into the market, seeing vast potential for future growth. Only about 5% of Chinese households currently own a robot vacuum cleaner, compared with around 15% in the United States, according to Tianfeng Securities. Drone maker DJI, home appliance giant Midea and robot start-up Pudu Robotics have all recently launched their own robot vacuum devices. Meanwhile, the leading manufacturers are broadening their portfolios to cover a wider range of robotic cleaning solutions and traditional home appliances, said IDC’s Zhao. “This market still has blue-ocean potential, but every company faces great pressure,” Su said, as reported by the South China Morning Post.
According to Future Market Insights, the robotic vacuum cleaner market is growing rapidly as consumers seek smart home solutions that are convenient, efficient, and hygienic. Robotic vacuum cleaners have evolved from luxury appliances to everyday essentials with the advancements in artificial intelligence, automation, and app-based controls. Busy lifestyles and increasing hygiene awareness are fueling demand for these products, coupled with the growing adoption of smart home ecosystems. The three global leaders, iRobot, Ecovacs, and Roborock take home a formidable 50% market share due to innovations in technology, ease of usability, and wide retail presence. Independent players and regional brands make up 30% offering cost-effective options and specialized cleaners. The remaining 20% is for the start-ups that are presently working on AI-based navigation with self-emptying technology and multi-surface adaptability. The robotic vacuum cleaner market in 2025 is highly concentrated, with the top players accounting for 50% to 65% of the total market share. Leading brands such as iRobot, Ecovacs, and Roborock dominate the segment, while AI-driven navigation and self-emptying features add competitive diversity. This market structure reflects strong brand influence while allowing space for affordable smart home integrations and multi-surface cleaning advancements.
