 SMART
engineers have combined deep-cleaning power with a patented noise reduction
package (a standard feature on the +/quiet models) to create a central
vacuum system that provides virtually silent operation! it's so quiet,
you can enjoy the freedom of vacuuming when others are studying, resting
or sleeping nearby - or even in the same room.

sound-absorbing materials and a unique patented sound-off muffler reduce
noise levels without reducing power. it's a smart solution for many families.
