RainVac, a division of Vertex Worldwide, Inc., has been in business since 1992. The company has risen to its current position in the marketplace based on one very important principle: customer service. Unlike most companies that deal in the Rainbow Cleaning System, we are not a sales-based business. Rather, we feel that the attention and training of our employees needs to be focused on service to our customers. The product can sell itself based on its superior design and engineering. Our customers are what set us apart from the rest. If they are happy with the service they receive, they will continue to return. That is why we have become the largest Rainbow parts and service company in the world.
