For most people, the first robot they own at home is often a robotic cleaning machine. These helpful devices require very little effort to use and do a great job keeping floors clean. They have become very popular in households around the world.

Among the top five robotic cleaner brands globally, four are from China. Roborock is the leader with a 20.7% market share. It is followed by Ecovacs, Dreame, and Xiaomi. The only non-Chinese brand in the top five is iRobot from the United States.

iRobot was one of the earliest companies to make robotic cleaners. It started in 1990 and became very successful. By 2012, it had more than 80% of the global market. But in recent years, Chinese companies have gained ground. Their products are now often better in performance and user experience. Facing strong competition, iRobot has run into trouble. Its stock price has dropped greatly, and its market value is now very low. Meanwhile, Chinese brands have grown quickly. Together, they now hold more than half of the global market.

Besides cleaning robots, other kinds of home robots are also becoming popular overseas. For example, in places like the US and Europe, many homes have large yards. Robotic lawn mowers are now taking over the job of cutting grass. They are smart, energy-saving, and easy to use. The global market for these robots is growing fast. Chinese companies are also doing very well in this area. Brands like KumoTech and Ecovacs are selling more and more products abroad.

Another example is the robotic pool cleaner. Many families in Western countries have swimming pools that need regular cleaning. Aiper, a brand made by a company from Shenzhen, has become a leader in this field. It holds over 35% of the market on Amazon and has been the top wireless pool cleaner for three years.

Chinese home robots are winning hearts around the world with their smart design, good quality, and reasonable prices. They are not only changing how people live but also showing the world the power of Chinese innovation.
