Chinese home appliance maker Dreame Technology said Tuesday it will launch its next-generation premium robot vacuum cleaner, the Aqua20 Ultra Roller, in South Korea, featuring a combination of high-temperature steam and a hot-water roller mop. Founded in 2017, Dreame Technology is a global premium technology brand offering smart home appliances, home care products and smart mobility solutions. The Aqua20 Ultra Roller features what the company calls Korea's first "Dual High-Temp Steam Mopping" system, combining steam heated to 180 degrees Celsius with a hot-water roller mop. The system applies steam directly to the floor to loosen tough, dried-on dirt before the roller mop removes it. Fresh hot water is continuously supplied to the rotating roller, while a built-in metal blade scrapes away dirt during cleaning.
