X Square Robot, a Chinese embodied AI developer, raised funding that values the company at more than $2.8 billion（約4500億円）, bringing together strategic investors including Xiaomi and HongShan. The company is deploying household robots in real homes through partnerships and a family trial program, using operational data to improve its foundation models. This move from staged testing to real-world deployment may indicate that practical embodied AI systems are beginning to function in complex home environments.

X Square Robot, a Shenzhen-based embodied AI company, closed four consecutive financing rounds culminating in a Series C, bringing its valuation to more than $2.8 billion（約4500億円）. The company plans to invest the funding in foundational research and core technologies to advance toward general-purpose embodied AI.
Why it matters
X Square Robot is moving household robots from demos into real homes—it has partnered with 58.com to deploy AI-powered cleaning robots in Shenzhen and Beijing, and launched a "X Family Member Program" where robots live with families for up to one month. This real-world deployment creates feedback loops that improve the company's models, a potential signal that practical embodied AI systems are beginning to work in everyday environments.
What to watch
The company introduced WALL-B, a foundation model built on its World Unified Model architecture, in April 2026. An open-source version, WALL-OSS-0.5, achieved over 80% autonomous completion on four of 17 real-robot tasks without post-training, suggesting progress toward robots that can generalize across multiple household tasks.
