3i
3i is a premium robot vacuum and mop brand from Shenzhen Picea Robotics, a Chinese manufacturer founded in 2016 and formerly called Shenzhen 3irobotix. Picea launched the 3i brand in 2022 to sell its own robots rather than only building them for other companies. The range includes the S10 Ultra with WaterRecycle technology, the P10 Ultra and the G10+, which 3i says is the first robot vacuum with onboard debris compression, storing up to 60 days of dirt in a 1,000 ml bin, and an extendable UltraReach mop for corners and edges. At CES 2024 3i showed the H1 Pro, a water-free cleaning station that recycles wastewater and pulls moisture from the air. 3i reports more than 4 million units shipped in 2024, more than 1,600 patents and R&D centres in Shenzhen, Tokyo and Silicon Valley, and sells in the United States, Germany, Italy, Spain and France. Its parent Picea, which builds vacuums for brands such as SharkNinja and Eufy, took control of iRobot in late 2025.
💡Notable Achievement: 3i launched the G10+, which it calls the first robot vacuum with onboard debris compression, on 3 June 2025; its parent Picea took control of iRobot in late 2025.
