## About

Headquartered in Shanghai, China and founded in 2022, Particle Evolution (Shanghai) Robotics Co., Ltd., doing business as xLean, provides intelligent home cleaning solutions through its Family Agent OS platform. The company was established by CEO Kehan Xue, a researcher previously at the Chinese University of Hong Kong with experience in high-revenue robotics projects. In April 2026, the company closed a round of venture funding.

The company provides users with the xLean TR1, a floor-washing robot capable of transforming into a handheld unit for manual cleaning. The device features 17,000 Pa suction, a dual-motor system, and an OMNI station that automatically handles waste separation and hot water washing. Its software utilizes reinforcement learning from human feedback (RLHF) to adapt cleaning strategies and improve obstacle avoidance based on how the user handles the device in manual mode.

The company generates revenue from the sale of cleaning robots, consumables and replacement parts via its direct-to-consumer platform and third party marketplaces.
