3i

3i is a smart-home brand dedicated to robotic cleaning, especially robot vacuums and vacuum-mop combinations. Their parent is PICEA, a robotics company that handles manufacturing for cleaning devices. In 2025, 3i made its first appearance at IFA, unveiling new models and emphasizing its push toward compact but powerful cleaning robots.

Though the brand is relatively new in the consumer spotlight, 3i leans on a deep background in robotics manufacturing. Some industry observers note that their pedigree includes work as an OEM or ODM for other robot vacuum brands before launching 3i's own line.
