The Amazing Stealth Belt

In an unprecedented move today, M.D. Manufacturing Inc. announced their first ever retail broken belt on the famous Stealth Power Brush. Originally introduced in 1993, this brush has offered an outrageous $100 of merchandise to the first end-user who ever broke a belt. Now, with almost 50,000 brushes in service, the inevitable has finally happened!

Shirley Friedman of Valley Village, California sent in her belt and it is clearly evident that it actually broke! An interview with her revealed that the brush was about four and a half years old and her cleaning girl, Jeannette, was using the system when she heard the “snap” that signaled the belt had, in fact, broke.

MD Manufacturing engineers inspected the brush this week and stated “We’ve never seen anything like it!” The preliminary diagnosis shows that it somehow frayed on the ridge of one of the cogs and later had a blunt force trauma compound the energy through that precise location initiating a chain reaction of disintegration within the fiberglass reinforcements. “Then basically it ripped,” stated Mike Kretsinger of M.D. Manufacturing.

No other powerbrush in the world can boast of the belt life proven by M.D. Manufacturing. An onboard computer within the powerbrush immediately disengages the roller brush in the unlikely event of any over-current. This eliminates the potential of prolonged tension on the brush when it might jam on a throw rug or electrical cord. Furthermore, the computer notifies the user of inappropriate carpet height settings that might cause undue strain on the motor and belt or on the carpeting surface itself. The computer even limits the free-spinning ability of the brush on hard surfaces.

Aided by a computer balanced motor and a computer balanced roller brush, the brush runs extremely smooth adding to the brush life. Lastly, the brush employs rubber cushioned sealed ball bearings in the end of the roller brush which further extends the life of the belt.

MD Manufacturing’s dealers absolutely love the brush because it eliminates senseless service calls. “I’ll install a system and not hear back from the client in seven years because of the reliability of the product,” states Glenn Troness of Placerville, California. “And when they do call it is because they are moving and want me install another system in their new home.”

Richard Spink, salesman for Mrs. Friedman’s brush was also quite shocked by the call claiming the belt had broken. “Initially I didn’t believe her because I knew of the virtual impossibility of the situation,” stated Richard, but he quickly repaired the brush with a free new belt. As for Mrs. Friedman, she received her $100 worth of free goods and purchased an additional $200 worth. She stated how much she truly loves her MD Central Vacuum and even purchased one for her son’s home.

In recognition of this momentous occasion, M.D. Manufacturing Inc. has chosen to increase it’s belt warranty from 5 years all the way to a lifetime guarantee! Yes, MD will provide a free belt to all retail residential applications that have a belt failure due to breakage. Abuse or intentional breakages will not be covered.
So after 12 years of offering $100 to the first client, the prize has finally been awarded. Special thanks goes to all vacuum dealers who have been faithfully representing this brush.
