Within the Public Toilet Robot ecosystem, value creation begins with upstream suppliers that provide structural components, power sources, and consumable cleaning agents. These inputs feed midstream actors—technology firms that embed perception, navigation, and disinfection algorithms, and OEMs that integrate hardware into a compliant robot platform. System integrators then combine hardware, software, and connectivity layers to enable remote monitoring, while distributors channel the finished systems to municipal and venue procurement processes. The downstream tier consists of end‑users such as city governments, airport authorities, and stadium operators, which purchase robots to meet public‑health standards and operational efficiency goals. Revenue is captured at each handoff through component sales, licensing fees, integration contracts, distribution margins, and service agreements.
