Primech AI’s HYTRON Robot Achieves >99%Disinfection Efficacy, Targeting $76.7B U.S. Commercial Health Market

SINGAPORE, Oct. 09, 2025 (GLOBE NEWSWIRE) -- Primech Holdings Ltd. (“Primech” or the “Company”), a leader in AI-powered hygienic robotics, today announced that its flagship HYTRON autonomous cleaning robot achieved bacterial reduction exceeding 99% in independent testing conducted by a top-tier laboratory. The comprehensive analysis demonstrated exceptional disinfection performance, which is consistent withthe performance thresholds required for hospital-grade disinfectants in the United States.

HYTRON’s independently tested performance positions Primech to capitalize on the $76.7 billion U.S. commercial cleaning market, a sector increasingly shaped by wellness-aligned operations and measurable hygiene outcomes. As the global commercial cleaning robotics market expands at a projected 15.1%CAGR, Primech is strategically positioned to capture post-COVID momentum, meeting rising corporate and institutional priorities for verified hygiene, reduced labor dependency, and AI-driven operational efficiency.

“These testing results mark an important milestone in Primech’s evolution from a robotics provider to an AI-driven robotics innovator redefining hygiene standards. This is grounded in our experience deploying HYTRON in a leading hospital in Singapore under live conditions,” said Ken Ho, Chairman and CEO of Primech. “HYTRON’s electrolyzed water technology reduces chemical dependency while delivering hospital-grade disinfection—proving that sustainability and efficacy can coexist. We’re not only automating hygiene—we’re quantifying wellness so that facilities can confidently position their spaces as premium, health-conscious environments.”

This testing reinforces HYTRON’s growing commercial traction, following over 250 qualified inquiries generated from live demonstrations at CMS Berlin 2025 and continued expansion initiatives across Europe, North America, the Middle East, Oceania and Asia. With independently verified disinfection performance and surging global demand for AI-powered wellness and hygiene solutions, Primech is advancing toward industry leadership in the digital transformation of global facility management.
