Operating System 1 (OS1™) is a comprehensive cleaning system. It employs in-depth training based on standardized tools and procedures. The process is workloaded to teams and each worker is trained and certified on specialized tasks. Workers are equipped with specific tools and chemicals for each job function, which have been benchmarked as the best practice by the (OS1™) Users. This simplification of the cleaning process results in a safer, healthier and easier working environment.
