When Rotobrush opened for business, we provided air duct cleaning services with our own patented brush-and-vacuum method. As word spread, more and more contractors expressed interest in owning a Rotobrush system of their own—and so we evolved from a service provider to a manufacturer of air duct cleaning equipment, supplies, and video inspection systems. During this time we patented our brush-and-vacuum method—the one homeowners prefer 2 to 1—along with a removable pod design. By 1998, we were listed as one of Inc. magazine’s 500 fastest growing companies.
