More Things To Know...

No, You're Not Dreaming
Cen-Tec's new line of Whisper-Drive III electric brushes are the quietest brushes on the market. That's not an accident. Years of testing and research went into the design of a "belt system" that makes Whisper-Drive III electric brushes significantly quieter.

The Secret To Quieter Brushes
What makes Whisper-Drive III belts less noisy that traditional "geared belt" systems is the superior "V" shape of the belt profile. It's the same "serpentine" shape that allows your car to run more smoothly - with less noise and longer life.

Form Follows Function
"V" belt profiles have another big advantage: the gripping "force" or "pull"  between the motor and the agitator is "inline" with the direction that the brushroller is turning. With a brush that is always in contact with the motor: it's easy to achieve a smooth transfer of power from the motor to the brush. On the other hand, in systems where the belt designs require the constant intermeshing of belts and gears, repetitive engagement create mechanical and vibrational noise that's only magnified as RPM's rise. That's noise!

The Right Kind of Pull
In cleaning, like politics, it helps to have the right kind of pull. The "V" construction of Whisper-Drive III belts have a contact surface area with the motor pully and the agitator that is significantly greater than traditional geared belts. More surface area contact translates into better grip and mechanics for transferring power to the brush; the kind positive drive you'll appreciate when moving the powerhead from commercial grade carpet to heavier plush.

Belt Life
Engineered to exceed the life of traditional "geared" belts, the Whisper-Drive III "V" is impregnated with mylar fibers for a belt that won't stretch or fatigue over time or heavy use.
