M.D. Manufacturing, Inc.

M.D. Manufacturing, Inc.'s number one passion is and has always been the central vacuum industry. In 1961, before household brand names threw their hat into this product line, M.D. Manufacturing was already miles ahead.

It all started with Charles Emdy who, as a 56-year old metal worker with only an 8th grade education, wanted to make something that would better society, provide for his family, and allow him to give back to the community. Little did he know when he began selling central vacuum systems out of his North Hollywood garage in the early sixties that his dream would become a reality.

For the next five decades, M.D. Central Vacuum would not only invent and design helpful products and patent better vacuums but it would grow into a company with worldwide distribution and a robust dealer network. Our dealers are a cherished alliance as they best meet the individual needs of our customers. Indeed, selling M.D. Manufacturing power units SilentMaster, ModernDay, Flo-Master and industry acclaimed power brush Stealth, are sold through dealers ensuring top-level, personalized local service. At the same time, our ever-growing website is an industry standard for everything related to central vacuums and is a wealth of information for both professionals and homeowners.

Fifty years after Charles Emdy designed his central vacuum prototype and began selling units out of his garage, M.D. Manufacturing is now one of the largest central vacuum manufacturers in North America. Our passion is to manufacture high quality products and provide accurate, personalized, first-rate customer service at competitive prices. Best of all, the founder's original goals are coming true: customers experience the practical and healthful benefits of an outstanding product; employees provide for their families; and M.D. gives back to the community and our affiliates through gifts and scholarships.
